Description

Film forming device and part peeling device

The present invention relates to a film forming apparatus that forms a film on an electronic component that has been adhered to a protective sheet, and a part peeling apparatus that peels the electronic component on which the film is formed from the protective sheet.

In a wireless communication device typified by a mobile phone, many electronic components such as semiconductor devices are mounted. The electronic component is transported from the processing apparatus to the processing apparatus in order to undergo various processes. A representative example of the treatment is the formation of an electromagnetic wave shielding film. In order to prevent the influence on the communication characteristics, the electromagnetic wave shielding film suppresses the influence of electromagnetic waves such as leakage of electromagnetic waves to the outside on the inside and the outside. In general, an electronic component is formed into a shape by a sealing resin, and a conductive electromagnetic wave shielding film is provided on the top surface and the side surface of the sealing resin in order to shield electromagnetic waves (see Patent Document 1).

As a method of forming an electromagnetic wave shielding film, an electroplating method is known. However, the electroplating method requires a wet step such as a pretreatment step, a plating treatment step, and a post-treatment step such as water washing, so that an increase in the manufacturing cost of the electronic component cannot be avoided. Therefore, a sputtering method as a dry step is attracting attention. In the sputtering method, an inert gas is introduced into a vacuum vessel in which a target is disposed, and a direct current voltage is applied. Thus, the ions of the plasma-inert inert gas collide with the target of the film-forming material, and the particles that have been ejected from the target are deposited on the electronic component. This buildup layer becomes an electromagnetic wave shielding film.

A film forming apparatus for realizing a sputtering method includes a cylindrical chamber which is a vacuum chamber inside, a rotary table housed in the chamber and having a rotating shaft coaxial with the chamber, and a film forming position divided in the chamber . The electronic component is placed on the turntable, and the turntable is rotated in the circumferential direction, whereby the electronic component is brought to the film position, and the electromagnetic wave shielding film is formed into a film. As such, there is also a rotational transport of electronic components in the processing device.

In the conveyance of the electronic component inside and outside the device, the electronic component is subjected to an inertial force due to acceleration, deceleration, rotation, or the like, and there is a concern that the electronic component is reversed or falls off from the film formation position. Therefore, the electronic component is adhered to the adhesive film, and is subjected to filming of the transfer and electromagnetic wave shielding film (see Patent Document 2). The electronic component can be held in place by the adhesion against inertial forces.

Conventionally, an electronic component that has been adhered to an adhesive film is peeled off from an adhesive film by using an upper device (see Patent Document 3). As shown in Fig. 29, the upper top device includes a pin body 8 that is movable in the axial direction. An adhesive film 9 to which the electronic component 60 is adhered is provided at the front end of the pin body 8. The pin body 8 is adhered to the top surface 9 from the side opposite to the adhesion surface of the electronic component 60. The pin body 8 deforms the adhesive film 9 into a mountain shape in which the electronic component 60 to be peeled off is set as a vertex. Therefore, the adhesion area of the electronic component 60 and the adhesive film 9 is reduced, whereby the electronic component 60 is peeled off from the adhesive film 9.

[Patent Document 1] Patent Document 1: International Publication No. 2013/035819. Patent Document 2: Japanese Patent Laid-Open No. Hei 6-97268.

[Problem to be Solved by the Invention] As shown in FIG. 30, a plurality of electronic components 60 are adhered to the adhesive film 9 with a gap therebetween. From the viewpoint of production efficiency, the interval of the electronic component 60 adhered to the adhesive film 9 is narrow. Therefore, if one electronic component 60 is topped up, the strain of the adhesive film 9 also spreads to the adhesion area of the adjacent electronic component 60. Then, in a period in which the object to be peeled is lifted upward, a part of the adjacent electronic component 60 may be peeled off from the adhesive film 9 to cause the peeling portion 91.

When the peeling of the peeling target is completed, the pin body 8 retreats in the axial direction, and thus the deflection of the adhesive film 9 is eliminated. Then, the adhesive film 9 adheres again to the peeling portion 91, and the reattachment portion 92 of the adhesive film 9 is generated in the electronic component 60. FIG. 31 is a photograph showing the state of the electrode 602 after the adhesive film 9 is again attached to the electronic component 60 and peeled off. As shown in FIG. 31, when the adhesive film 9 adheres again, the residue 93 of the adhesive film 9 may be generated in the electrode 602. The residue 93 of the adhesive film 9 may be burned and carbonized during reflow of the electronic component 60 when it is packaged, and may cause connection failure or the like.

The present invention has been made to solve the problems as described above, and an object of the invention is to provide a film forming apparatus and a component peeling apparatus which can prevent an electronic component from remaining on an electronic component and peel off an electronic component from which a film has been formed. .

[Effects of the Invention] According to the present invention, it is possible to prevent residue from remaining on the electronic component and to peel off the electronic component on which the film formation has been completed from the protective sheet.

(Electronic Component) FIG. 1 is a side view showing an electronic component subjected to a film formation process. As shown in FIG. 1, an electromagnetic wave shielding film 605 is formed on the surface of the electronic component 60. The electronic component 60 is a surface mount component such as a semiconductor chip, a diode, a transistor, a capacitor, or a Surface Acoustic Wave (SAW) filter. The semiconductor chip is an integrated circuit such as an integrated circuit (IC) or a large scale integrated circuit (LSI) in which a plurality of electronic components are integrated. The electronic component has a Ball Grid Array (BGA), a Land Grid Array (LGA), a Small Outline Package (SOP), and a Quad Flat Package (QFP). A substantially rectangular parallelepiped shape such as a wafer level package (WLP) is used as the electrode exposure surface 601. The electrode exposure surface 601 is a surface on which the electrode 602 is exposed and is opposed to the package substrate and connected to the package substrate. The electrode 602 is an electrode called a spherical bump or a solder ball bump, and is formed by mounting a spherical solder (solder ball) having a diameter of several tens of μm to several hundreds μm on a pad electrode.

The electromagnetic wave shielding film 605 shields electromagnetic waves. The electromagnetic wave shielding film 605 is formed of, for example, a material such as Al, Ag, Ti, Nb, Pd, Pt, or Zr. The electromagnetic wave shielding film 605 may be formed of a magnetic material such as Ni, Fe, Cr, or Co. Further, a film of SUS, Ni, Ti, V, Ta or the like may be formed as a base layer of the electromagnetic wave shielding film 605, and a film of SUS or Au may be formed as the outermost protective layer.

The electromagnetic wave shielding film 605 is formed on the top surface 603 and the side surface 604 of the electronic component 60, that is, the outer surface other than the electrode exposure surface 601. The top surface 603 is a surface opposite to the electrode exposed surface 601. The side surface 604 is an outer peripheral surface that connects the top surface 603 and the electrode exposure surface 601 and is extended at an angle different from the top surface 603 and the electrode exposure surface 601. In order to obtain a shielding effect of blocking electromagnetic waves, the electromagnetic wave shielding film 605 may be formed on at least the top surface 603. On the side 604 there is a ground pin outside the figure. The formation of the electromagnetic wave shielding film 605 for the side surface is also for the grounding of the electromagnetic wave shielding film 605. In addition, in the state in which the electromagnetic wave shielding film 605 is formed, the electronic component 60 may include an electromagnetic wave shielding film 605 and is referred to as an electronic component 60. Further, the top surface 603 and the side surface 604 are also referred to as the top surface 603 and the side surface 604 regardless of whether the electromagnetic wave shielding film 605 is formed or the electromagnetic wave shielding film 605 is not formed. That is, the surface of the electromagnetic wave shielding film 605 formed on the top surface 603 of the electronic component 60 is also referred to as a top surface 603, and the surface of the electromagnetic wave shielding film 605 formed on the side surface 604 is also referred to as a side surface 604.

(When Film Forming Process) FIG. 2 is a side view showing a state of the electronic component subjected to the film forming process. In addition, FIG. 3 is an exploded perspective view showing a state of the electronic component when the film forming process is performed. As shown in FIGS. 2 and 3, the electrode 602 of the electronic component 60 is embedded in the protective sheet 61 in advance, and the electrode exposed surface 601 is in close contact with the protective sheet 61. By the embedding of the electrode 602 in the protective sheet 61, the particles of the electromagnetic wave shielding film 605 are prevented from reaching the electrode 602 at the time of film formation. Further, by the adhesion between the electrode exposed surface 601 and the protective sheet 61, the space between the particles of the electromagnetic wave shielding film 605 entering the electrode exposed surface 601 and the protective sheet 61 is also lost, and the particles of the electromagnetic wave shielding film 605 are likely to reach the electrode 602. Sexual decline.

The protective sheet 61 is a heat-resistant synthetic resin such as polyethylene naphthalate (PEN) or polyimide (PI). One surface of the protective sheet 61 is an adhesive surface (adhesive layer) 611 having adhesiveness in which the electrode 602 is immersed and adhesively adhered to the electrode exposed surface 601. As the adhesive surface 611, an anthrone-based or acrylic-based resin, and various materials having adhesive properties such as a urethane resin or an epoxy resin can be used.

The adhesive surface 611 is divided into an outer frame region 613 that reaches a predetermined distance from the end of the protective sheet 61 toward the inner side, a middle frame region 614 that reaches a predetermined distance from the inner circumference of the outer frame region 613, and a middle frame region. 614 is a more inner part arrangement area 615. The electronic component 60 is adhered to the part arrangement area 615. A frame-like frame 62 is adhered to the outer frame region 613. The middle frame region 614 is a range in which the warpage of the protective sheet 61 is generated, and neither the frame 62 nor the electronic component 60 is pasted. Further, the opposite surface of the adhesive surface 611 is a non-adhesive surface 612. The area of the non-adhesive surface 612 corresponding to the outer frame area 613, the middle frame area 614, and the part arrangement area 615 is also simply referred to as an outer frame area 613, a middle frame area 614, and a part arrangement area 615.

The protective sheet 61 is adhered to the cooling plate 63 via the adhesive sheet 64. The cooling plate 63 is made of a metal such as SUS, ceramics, resin, or other material having high thermal conductivity. This cooling plate 63 is a heat dissipation passage that discharges heat of the electronic component and suppresses excessive heat storage. The adhesive sheet 64 has adhesiveness on both sides, improves the adhesion between the protective sheet 61 and the cooling plate 63, and ensures a heat transfer area toward the cooling plate 63.

The height H1 from the surface of the part arrangement area 615 to the upper end surface of the frame 62 is higher than the height H2 from the surface of the part arrangement area 615 to the top surface 603 of the electronic component 60 (see FIG. 4). Further, there is a case where the height H1 is changed to the thickness H1 for convenience, but the meaning is the same. In summary, if the panel is placed on the frame 62, the top surface 603 of the electronic component 60 does not reach the panel.

A guide insertion hole 621 is formed in one end of the frame 62. The guide insertion hole 621 has a long elliptical, rectangular, circular, or the like opening along the end of the frame 62, and penetrates through the surface of the frame 62 adhered to the protective sheet 61 and its opposite exposed surface. In other words, for example, when the rod-shaped member is inserted into the guide portion insertion hole 621 and the end portion of the protective sheet 61 is pressed (see (a) to (f) in FIG. 18), one end portion of the protective sheet 61 is from the frame 62. Stripped on.

A pusher insertion hole 631 is formed in the cooling plate 63 and the adhesive sheet 64. The push rod insertion hole 631 does not coincide with the guide insertion hole 621 and is disposed at a position blocked by the frame 62. The plurality of push rod insertion holes 631 are disposed in such a manner that if, for example, a rod member is inserted into the push rod insertion hole 631, and the frame 62 is pushed up by the front end of the rod member, the frame 62 as a whole is raised in parallel . For example, if the frame 62 is a frame having a rectangular outer shape, the push rod insertion holes 631 are located at the four corners, or further at the center of each side. From the viewpoint of maintaining the parallelism of the frame 62, the rod-shaped member preferably has a rectangular front end surface, that is, a thin plate shape or a cross-sectional L-shaped shape, but is not limited thereto, and may have a circle. The front face of the shape. The push rod insertion hole 631 has a rectangular shape, an L shape, or a circular shape correspondingly.

Further, on the cooling plate 63 and the adhesive sheet 64, a plurality of fine air holes 632 are formed in the range of the component arrangement region 615 of the adhesive protection sheet 61. This air hole 632 is, for example, a micro cylinder shape or a slit shape. In order to uniformly apply a negative pressure or a positive pressure to at least the part arrangement region 615 of the protective sheet 61 adhered to the cooling plate 63 through the air holes 632, the air holes 632 are provided.

(Film forming process flow) In the film forming process, the electromagnetic wave shielding film 605 is formed by the component mounting step, the component embedding step, the board mounting step, the film forming step, the board removing step, and the part peeling step. Separated into a single piece of electronic component 60.

4 is a view showing a flow of a film forming process of an electronic component. As shown in FIG. 4, in the component mounting step, the electronic component 60 is arranged in a state where the electrode exposed surface 601 of the electronic component 60 and the component unattached sheet 65 on which the frame 62 has adhered to the protective sheet 61 are opposed to each other. In the part arrangement area 615. The frame 62 is adhered to the protective sheet 61, and the electronic component 60 is further arranged. However, the state in which the electrode 602 has not been buried is referred to as a component mounted sheet 66.

In the part embedding step, the electrode 602 is buried in the protective sheet 61 for the component-mounted sheet 66, and the electrode exposed surface 601 is adhered to the protective sheet 61. The state in which the electrode 602 has been buried in the protective sheet 61 regardless of the formation and non-formation of the electromagnetic wave shielding film 605 is referred to as a part-embedded sheet 67. In the board mounting step, the parts embedded in the sheet 67 are adhered to the cooling plate 63 via the adhesive sheet 64. The state in which this cooling plate 63 is attached is called a component mounting board 68.

In the film forming step, particles of the electromagnetic wave shielding film 605 are deposited from the top surface 603 side of the electronic component 60, and an electromagnetic wave shielding film 605 is formed on the electronic component 60. At this time, the electrode 602 of the electronic component 60 is buried in the protective sheet 61, and the electrode exposed surface 601 is in close contact with the protective sheet 61, and the particles of the electromagnetic wave shielding film 605 are prevented from adhering to the electrode 602.

In the board releasing step, the cooling plate 63 is removed, and the form in which the parts have been embedded in the sheet 67 is restored. Then, in the part peeling step, the electronic component 60 and the frame 62 are peeled off from the protective sheet 61, and separated into the protective sheet 61 and the respective electronic components 60 and the frame 62. The film formation process is completed by the above method.

(Film Forming Apparatus) The film forming apparatus which is responsible for the parts embedding step, the board mounting step, the film forming step, the sheet releasing step, and the part peeling step in the above-described film forming process flow is shown in FIG. 5. As shown in FIG. 5, the film forming apparatus 7 includes an embedding processing unit 1, a board mounting unit 2, a film forming processing unit 3, a board releasing unit 4, and a peeling processing unit 5. The respective units are connected by the conveying unit 73, and the members required in the respective steps are loaded, and the members that have been processed in the respective steps are discharged. The conveying unit 73 is, for example, a conveyor, and may be a conveying table that is movable along a linear rail by a ball screw or the like.

Further, the film forming apparatus 7 houses a control unit 74 such as a computer or a microcomputer, and has a central processing unit (CPU), a read only memory (ROM), and a random access memory ( a random access memory (RAM) and a signal transmission circuit for controlling the operation timing of each component included in the embedding processing unit 1, the board mounting unit 2, the film forming processing unit 3, the board releasing unit 4, and the peeling processing unit 5 ( Timing). Further, the air pressure circuit 75 is housed, and a positive pressure or a negative pressure is supplied to the embedding treatment unit 1, the plate attachment portion 2, the film formation processing unit 3, the plate release portion 4, and the peeling treatment portion 5. The control unit 74 also controls the solenoid valve in the air pressure circuit 75 to switch between generating a negative pressure, releasing the negative pressure, generating a positive pressure, and releasing the positive pressure.

(Embedded Processing Unit) The embedded processing unit 1 that is responsible for the component embedding step will be described. FIG. 6 is a schematic view showing the configuration of the embedding treatment unit 1. The component mounted sheet 66 is placed in the embedded processing unit 1. The embedding treatment unit 1 sucks the protective sheet 61 onto the electronic component 60 while blocking the electronic component 60, and presses the protective sheet 61 against the electronic component 60. Thereby, the embedding processing unit 1 causes the electrode 602 of the electronic component 60 to be caught in the protective sheet 61, and the electrode exposed surface 601 is in close contact with the protective sheet 61.

As shown in FIG. 6, the embedding treatment unit 1 includes a top portion 11 and a mounting table 12. The top portion 11 and the mounting table 12 are blocks having an internal space 111 and an internal space 121 together. The top portion 11 is disposed to face the mounting table 12, and has a flat surface 112 and a flat surface 122 which are parallel to each other on the opposite side. The two flat faces (112, 122) are the same size or shape as the component has been placed 66 or wider than the component has placed 66. The position of the stage 12 does not move. On the other hand, the top portion 11 can be raised and lowered with respect to the mounting table 12. The top portion 11 is at least close to the distance H1 of the frame 62 of the mounting table 12 to the component mounting piece 66.

A part-mounted sheet 66 is placed on this stage 12. The flat surface 122 of the mounting table 12 serves as a mounting surface on which the component mounting sheet 66 is placed. This flat surface 122 contains an anti-slip member having an adhesive force. Further, a plurality of air holes 123 leading to the internal space 121 are formed on the flat surface 122 of the mounting table 12. The air hole 123 is disposed in the same range and shape as the inner side of the frame 62 of the component-mounted piece 66, or at least the same size and shape as the part arrangement area 615. When the component-mounted sheet 66 has been placed on the mounting table 12, the position of the air hole 123 is a position opposed to the inner side of the frame 62 or a position opposed to the part arrangement area 615.

In the internal space 121 of the mounting table 12, a gas pressure supply hole 124 is further formed in a portion different from the flat surface 122. The air pressure supply hole 124 is connected to a pneumatic circuit 75 including a compressor, a negative pressure supply pipe, a positive pressure supply pipe, and the like outside the drawing. Therefore, a positive pressure or a negative pressure is selectively generated in the air hole 123 through the air pressure supply hole 124 and the internal space 121.

Further, on the flat surface 122 of the mounting table 12, the push rod insertion hole 125 that penetrates the mounting table 12 is opened. The push rod insertion hole 125 is disposed outside the extending range of the air hole 123. In detail, when the component mounting sheet 66 has been placed, the positioning position of the push rod insertion hole 125 is a position blocked by the frame 62 while avoiding the guide insertion hole 621 of the frame 62. The push rod 13 is inserted in this push rod insertion hole 125. The push rod 13 can be seen from the flat surface 122 of the mounting table 12. The push rod 13 is set such that the part mounting piece 66 is separated from the mounting table 12 when it has protruded from the push rod insertion hole 125, and can be set in parallel with the rigidity, the number, and the arrangement interval of the support. . For example, if the outer shape of the frame 62 is rectangular, the rods are arranged corresponding to the respective corners of the frame 62.

In turn, a plurality of air holes 113 leading to the inner space 111 are also formed on the flat surface 112 of the top portion 11. The air hole 113 is disposed in the same range and shape as the inner side of the frame 62 of the component-mounted piece 66, or at least the same size and shape as the part arrangement area 615, and extends over the entire part arrangement area 615. When the component-mounted sheet 66 has been placed on the mounting table 12, the position of the air hole 113 is a position opposed to the inner side of the frame 62 or a position opposed to the part arrangement area 615.

In the internal space 111 of the top portion 11, a gas pressure supply hole 114 is formed in a portion different from the flat surface 112. The air pressure supply hole 114 is connected to a pneumatic circuit 75 including a compressor, a negative pressure supply pipe, and the like outside the drawing. Therefore, a negative pressure is generated in the air hole 113 through the air pressure supply hole 114 and the internal space 111.

Further, on the flat surface 112 of the top portion 11, an O-ring 115 that surrounds the air hole 113 is provided along the frame 62 on which the component 66 placed on the mounting table 12 is placed.

(a) to (g) of FIG. 7 show the flow of the operation of the embedding processing unit 1. (a) to (g) of FIG. 7 are transition diagrams schematically showing the state of the embedding processing unit 1 in each step. First, as shown in FIG. 7(a), the component mounted sheet 66 is placed in the embedded processing unit 1. The top portion 11 is sufficiently separated from the mounting table 12, and the push rod 13 first protrudes from the flat surface 122 of the mounting table 12. When the component has been placed on the sheet 66, the frame 62 of the component-mounted sheet 66 is aligned with the pusher 13, and the component-mounted sheet 66 is supported on the pusher 13.

Then, as shown in FIG. 7(b), the push rod 13 is retracted toward the push rod insertion hole 125. Thereby, the component-mounted sheet 66 is lowered onto the flat surface 122 of the mounting table 12. Further, the top portion 11 is moved toward the mounting table 12. Further, the frame 62 of the component-mounted piece 66 is sandwiched by the flat surface 112 of the top portion 11 and the flat surface 122 of the mounting table 12. The height H1 from the surface of the part arrangement area 615 to the upper end surface of the frame 62 is higher than the height H2 from the surface of the part arrangement area 615 to the top surface 603 of the electronic component 60. Thus, when the frame 62 has been clamped, the top surface 603 of the electronic component 60 does not reach the flat surface 112 of the top portion 11. Therefore, the component arrangement region 615 carrying the electronic component 60 is enclosed in the sealed space 14 surrounded by the flat surface 112 of the top portion 11 and the protective sheet 61 and the frame 62, and sealed by the O-ring 115.

When the component array region 615 is sealed in the sealed space 14, as shown in FIG. 7(c), a negative pressure is generated in the air hole 123 of the mounting table 12, and the protective sheet 61 is adsorbed on the flat surface 122. Then, as shown in (d) of FIG. 7, a negative pressure is also generated in the air hole 113 of the top portion 11, and the sealed space 14 in which the component array region 615 is enclosed is depressurized. That is, the air holes (113, 123) of the top portion 11 and the mounting table 12 function as a pressure reducing portion. The degree of decompression is ideally the same as the pressure reached by the two air holes (113, 123) and close to the vacuum. The reason why the air hole 123 of the mounting table 12 first generates the negative pressure is that the air pressure on the lower side of the protective sheet 61 is suppressed relative to the upper side during the decompression of the sealed space 14 by first adsorbing the protective sheet 61 on the mounting table 12. The air pressure becomes too large, and thus the electronic component 60 swells rapidly toward the flat surface 112 of the top portion 11.

When the pressure reduction is completed, as shown in (e) of FIG. 7, the air hole 123 on the mounting table 12 side is gradually changed from the negative pressure to the positive pressure while maintaining the negative pressure on the top portion 11 side. The air hole 123 of the stage 12 is converted into a positive pressure. The electronic component 60 and the protective sheet 61 are slowly sucked up toward the flat surface 112 of the top portion 11, and are slowly pushed up. The electronic component 60 is pressed by the flat surface 112 of the top 11 to be blocked. On the other hand, since the protective sheet 61 has flexibility, the protective sheet 61 is further attracted toward the flat surface 112 even after the electronic component 60 has been blocked, and is further pushed upward toward the flat surface 112.

Then, the electrode 602 of the electronic component 60 is buried in the protective sheet 61, more specifically, in the adhesive surface 611 of the protective sheet 61, and further, the electrode exposed surface 601 of the electronic component 60 is in close contact with the protective sheet 61. At this time, the flat surface 112 of the top portion 11 includes the part arrangement area 615, and the part arrangement area 615 is followed by flatness. In other words, the part arrangement area 615 does not bend. Therefore, it is prevented that the electrode 602 is insufficiently buried at the end portion of the part arrangement region 615 or the electrode exposure surface 601 is insufficiently adhered.

The process of adhering the electrode exposed surface 601 to the protective sheet 61 is performed under a reduced pressure environment, and there is no air or a very small amount of air in the sealed space. Therefore, the possibility that air bubbles invade between the electrode exposed surface 601 and the protective sheet 61 becomes low.

Furthermore, FIG. 8 is an enlarged view of the electronic component 60 embedded in the processing unit 1. As shown in FIG. 8, the positive pressure generated in the mounting table 12 pushes up at least the part arrangement area 615 of the protective sheet 61 uniformly. Then, in each gap between the adjacent electronic components 60, the flexible protective sheet 61 is pushed further toward the flat surface 112 of the top portion 11 without being blocked by the electronic component 60. Then, the adhesive surface 611 of the protective sheet 61 is raised until reaching the lower portion of the side surface of the electronic component 60, and the protective sheet 61 is also in close contact with the lower portion of the side surface of the electronic component 60. Therefore, it is possible to more reliably prevent the particles of the electromagnetic wave shielding film 605 from entering between the electrode exposure surface 601 and the protective sheet 61.

When the electrode 602 of the electronic component 60 is embedded in the protective sheet 61, and the electrode exposed surface 601 of the electronic component 60 is in close contact with the lower surface of the protective component 61, the pusher is as shown in (f) of FIG. 13 moves in the axial direction along the push rod insertion hole 125 and reappears from the flat surface 122 of the mounting table 12. At the same time, the top portion 11 is separated from the mounting table 12 at a speed equal to the forward speed of the push rod 13. Finally, as shown in (g) of FIG. 7, the pusher 13 is stopped, and the top portion 11 is further separated from the mounting table 12, thereby releasing the sandwiching of the parts embedded in the sheet 67. Thereby, the embedding into the protective sheet 61 by the electronic component 60 embedded in the processing part 1 is completed.

Further, the negative pressure on the top 11 side and the positive pressure on the mounting table 12 side are as long as the adhesion to the protective sheet 61 from the electrode exposed surface 601 of the electronic component 60 in (e) of FIG. 7 is completed to (g) in FIG. It is sufficient to release the period in which the top portion 11 is raised. Regarding the negative pressure on the side of the top portion 11, if it is released immediately before the top portion 11 is raised in (g) in Fig. 7, the electronic component 60 can be stably stabilized when the push rod 13 in (f) of Fig. 7 is raised. It is preferably held on the protective sheet 61.

In this manner, the top portion 11 and the mounting table 12 are fixed portions that sandwich the component mounting piece 66 by sandwiching the frame 62 from both sides. Further, the top portion 11 and the protective sheet 61 and the frame 62 form a sealed space 14 enclosed in the component arrangement region 615. The O-ring 115 is sealed to improve the airtightness of the sealed space 14. Further, the air hole 113 of the top portion 11 serves as a pressure reducing portion that decompresses the sealed space 14.

Further, the flat surface 122 of the mounting table 12 serves as a mounting surface on which the component mounting sheet 66 is placed. The air hole 123 opened in the flat surface 122 of the mounting table 12 is an anti-collision member and a pressing member that firstly generates a negative pressure at the time of decompression of the sealed space 14 and prevents the electronic component 60 from facing the top portion 11 The flat surface 112 protrudes, and the pressing member interacts with the negative pressure of the top portion 11 by positive pressure to press the part arrangement region 615 against the flat surface 112 of the top portion 11 and embed the electrode 602 of the electronic component 60.

In addition, the flat surface 112 of the top portion 11 is a flattening member that improves the adhesion effect of the electrode 602 and the adhesion effect of the electrode exposed surface 601 by flattening the component array region 615. The air hole 113 opened in the flat surface 112 of the top portion 11 is a suction member and a side surface lower covering member which interact with the positive pressure of the mounting table 12 by a negative pressure to arrange the component arrangement region. 615 is pressed against the flat surface 112 of the top portion 11 and embeds the electrode 602 of the electronic component 60. The side lower cladding member interacts with the positive pressure of the mounting table 12 to suck the protective sheet 61 upward into the gap between the electronic components 60. The protective sheet 61 is adhered to the lower portion of the side of the electronic component 60.

In this way, the embedding processing unit 1 embeds the electrode 602 of the electronic component 60 in the adhesive surface 611 of the protective sheet 61, but has a decompression portion that decompresses the space including the electronic component 60 and the component arrangement region 615. Further, after the pressure is reduced, the electronic component 60 and the protective sheet 61 are pressed against each other. Therefore, there is no case where air bubbles enter between the electrode exposure surface 601 of the electronic component 60 and the protective sheet 61, and the adhesion is insufficient, and the gap between the electrode exposed surface 601 of the electronic component 60 and the protective sheet 61 may be lowered. A state in which particles of the electromagnetic wave shielding film 605 adhere to the electrode 602 is avoided.

In addition, the buried treatment portion 1 includes a flat surface 112 of the top portion 11. The flat surface 112 is located on the opposite side of the electronic component 60 from the protective sheet 61 and faces the electronic component 60. Further, the pressure between the mounting table 12 and the protective sheet 61, that is, the space on the opposite side of the protective sheet 61 from the flat surface 112 is relatively larger than the pressure in the space between the protective sheet 61 and the flat surface 112. Thereby, the electronic component 60 and the protective sheet 61 are directed toward the flat surface 112, the flat surface 112 is braked, and the electronic component 60 and the protective sheet 61 are mutually pressed. Therefore, the component arrangement region 615 of the protective sheet 61 is flattened, and the electrode exposed surface 601 of the electronic component 60 and the protective sheet 61 are pressed against each other in a state in which they have become parallel. Therefore, the room for bubble entry is further lost.

Further, the embedding treatment unit 1 has a mounting table 12, that is, a mounting surface (flat surface 122) on the opposite side of the protective sheet 61 from the flat surface 112. Further, an air hole 123 which is opened on the mounting surface and generates a negative pressure during the decompression of the sealed space 14 to separate the protective sheet 61 from the flat surface 112 is formed in the mounting table 12. Thereby, it is possible to suppress the electronic component 60 from being damaged by the electronic component rapidly protruding toward the flat surface 112 during the decompression process of the sealed space 14.

Further, the air hole 113 of the top portion 11 and the air hole 123 of the mounting table 12 for pressing the electronic component 60 and the protective sheet 61 are used as the pressure reducing portion. However, the third air hole may be separately formed in the sealed space 14 so that the third air hole may be formed separately. A negative pressure is generated in the third air hole to reduce the pressure.

Further, the air hole 123 on the side of the mounting table 12 is converted into a positive pressure after the pressure reduction of the sealed space 14, and the protective sheet 61 is further pressed toward the electronic component 60 blocked by the flat surface 112. Thereby, the protective sheet 61 and the adhesive surface 611 are swelled together in the gap between the electronic components 60, and the lower portion of the side surface of the electronic component 60 may be covered by the protective sheet 61. Therefore, it is possible to surely prevent a gap from being formed between the electrode exposed surface 601 and the protective sheet 61. Further, even in an electronic component such as SOP or QFP having a thin plate-shaped electrode on the lower side of the side surface, the electrode 602 is covered by the protective sheet 61, and the particles of the electromagnetic wave shielding film 605 can be prevented from adhering, and the film forming apparatus 7 can be applied.

In addition, the mechanism of action of the top portion 11 and the mechanism of action of the push rod 13 can employ well-known mechanisms, and the present invention is not limited by the mechanism of the mechanism.

For example, a ball screw that extends the shaft in the direction from the top portion 11 toward the mounting table 12 and a rail guide that extends in the direction from the top portion 11 toward the mounting table 12 are connected to the top portion 11. The top portion 11 moves along the guide rail toward the mounting table in accordance with the direction of rotation of the screw shaft. The ball screw and the rail guide are extended so that the top portion 11 approaches the distance H1 of the frame 62 of the component mounting sheet 66 from the mounting table 12.

Further, the rear end portion of the push rod 13 becomes a cam follower. The cam follower is driven on the circumferential surface of the oval cam. The camshaft is supported on the rotary motor and is rotatable in the circumferential direction. When the rotary motor is driven and the cam rotates, the cam follower raises the bulging portion of the cam, the push rod 13 is pushed upward, and the front end of the push rod 13 protrudes from the insertion hole.

Further, as a method of fixing the component mounting sheet 66, the frame 62 is sandwiched by the top portion 11 and the mounting table 12, and the sealed space 14 is formed by the top portion 11 and the protective sheet 61 and the frame 62, and the air of the mounting table 12 is placed. Both the positive pressure and the negative pressure are selectively generated in the hole 123, but are not limited thereto. For example, one or both of the top portion 11 and the mounting table 12 may be cup-shaped, and the component-mounted sheet 66 may be housed in the internal space formed by the top portion 11 and the mounting table 12. It is also possible to include a block that is sandwiched into the frame 62 from both sides, and the part-mounted piece 66 is held by the block. In this case, the height of the frame 62 is not limited. Both the through hole that generates the negative pressure and the through hole that generates the positive pressure may be formed on the flat surface 122 of the mounting table 12.

(Board Mounting Portion) Next, the board mounting portion 2 that is responsible for the board mounting step will be described. FIG. 9 is a schematic view showing the configuration of the board mounting portion 2. The parts 67 which have been formed by the embedding treatment unit 1 and the cooling plate 63 to which the adhesive sheet 64 has been adhered in advance are put into the board mounting portion 2. The board mounting portion 2 presses the component-embedded sheet 67 against the blocked cooling plate 63, and also sucks the part-embedded sheet 67 onto the cooling plate 63, thereby causing the part to be embedded in the sheet 67 via the adhesive sheet. 64 is in close contact with the cooling plate 63.

As shown in FIG. 9, the board mounting portion 2 includes a top portion 21 and a mounting table 22. The top portion 21 is disposed to face the mounting table 22. The position of the mounting table 22 does not move. On the other hand, the top portion 21 can be raised and lowered with respect to the mounting table 22. The top portion 21 is at least close to the distance from the mounting table 22 to the thickness H1 of the frame 62 in which the component has been embedded in the sheet 67.

The top portion 21 is a block having an internal space 211, and has a flat surface 212 on a surface facing the mounting table 22. The mounting table 22 has a bottomed cup shape. The opening 221 of the mounting table 22 faces the top portion 21. The flat surface 212 of the top portion 21 is the same size or shape as the part embedded in the sheet 67 or wider than the part embedded in the sheet 67. On the other hand, the opening 221 of the mounting table 22 has an area including the part arrangement area 615 or more and the middle frame area 614 or less. The edge portion 222 of the mounting opening 22 surrounding the opening 221 has a width greater than the width of the frame 62.

In this mounting table 22, the edge portion 222 supports the cooling plate 63, and the opening 221 is blocked by the cooling plate 63. The surface of the cooling plate 63 opposite to the surface to which the adhesive sheet 64 is adhered abuts on the edge portion 222. Further, the component-embedded sheet 67 is placed on the cooling plate 63 opposite to the adhesive sheet 64. A gas pressure supply hole 223 is formed in the bottom of the mounting table 22. The air pressure supply hole 223 is connected to a pneumatic circuit 75 including a compressor, a negative pressure supply pipe, and the like outside the drawing. Therefore, a negative pressure is generated in the air hole 632 of the cooling plate 63 placed to block the opening 221.

Further, a push rod insertion hole 224 that penetrates the mounting table 22 is formed in the edge portion 222 of the mounting table 22. The positioning position of the push rod insertion hole 224 is the same as the push rod insertion hole 631 of the cooling plate 63. When the part is embedded in the sheet 67 on one side, the guide insertion hole 621 of the frame 62 is avoided. The position blocked by the frame 62. The push rod 23 is inserted in this push rod insertion hole 224. The push rod 23 can pass through the mounting table 22, the cooling plate 63, and the adhesive sheet 64.

The push rod 23 is disposed in such a manner that the parts have been embedded in the cooling plate 63, such that the parts are embedded in the sheet 67 away from the cooling plate 63 and can be supported in parallel, such as the rigidity, the number, and the arrangement interval. For example, if the outer shape of the frame 62 is rectangular, it is arranged as a rod corresponding to each corner of the frame 62. The push rod insertion holes 224 are also provided corresponding to the number and positional relationship of the push rods 23.

In turn, a plurality of air holes 213 leading to the interior space 211 are disposed on the flat surface 212 of the top portion 21. The air hole 213 is disposed in the same range and shape as the inner side of the frame 62 in which the component is embedded in the sheet 67, or at least the same size and shape as the component arrangement region 615. When the component embedded sheet 67 has been placed on the mounting table 22, the position of the air hole 213 is the position covered by the part arrangement area 615 (refer to (a) of FIG. 10).

In the internal space 211 of the top portion 21, a gas pressure supply hole 214 is formed in a portion different from the flat surface 212. The air pressure supply hole 214 is connected to a pneumatic circuit 75 including a compressor, a positive pressure supply pipe, a negative pressure supply pipe, and the like outside the drawing. Therefore, positive pressure and negative pressure are selectively generated in the air holes 213 through the air pressure supply hole 214 and the internal space 211.

Further, on the flat surface 212 of the top portion 21, an O-ring 215 that surrounds the air hole 213 is provided along the frame 62 in which the components placed on the mounting table 22 are embedded in the sheet 67.

(a) to (e) of Fig. 10 show the flow of the operation of the board mounting portion 2. (a) to (e) of Fig. 10 are transition diagrams schematically showing the state of the board mounting portion 2 in each step. First, as shown in (a) of FIG. 10, the top portion 21 is first separated from the mounting table 22. A cooling plate 63 is placed on the mounting table 22 in advance. Further, the pusher 23 is first passed through the cooling plate 63 and the adhesive sheet 64 to protrude toward the top portion 21. In this state, the frame 62 in which the part has been embedded in the sheet 67 is aligned with the push rod 23, and the pusher 23 supports the part to be embedded in the sheet 67. Then, the top portion 21 is lowered toward the push rod 23, and the frame 62 in which the part has been embedded in the sheet 67 is sandwiched by the top portion 21 and the push rod 23.

At this time, the height H1 from the surface of the part arrangement area 615 to the upper surface of the frame 62 is higher than the height H2 from the surface of the part arrangement area 615 to the top surface 603 of the electronic component 60. Thus, when the frame 62 has been clamped, the top surface 603 of the electronic component 60 does not reach the flat surface 212 of the top portion 21. Therefore, at least the component arrangement region 615 is enclosed in the sealed space 24a formed by the top portion 21, the protective sheet 61 and the frame 62 and sealed by the O-ring 215.

When the part arrangement area 615 is sealed in the sealed space 24a, a negative pressure is generated in the flat surface 212 of the top portion 21. The electronic component 60 is attracted to the flat surface 212. The part-embedded sheet 67 is strained in the middle frame region 614, and the entire region of the part arrangement region 615 is attracted to the flat surface 212 in a flat state. Therefore, the part arrangement area 615 does not flex as bent, and the buried electrode 602 does not come off the protective sheet 61. Further, on the flat surface 212 of the top portion 21, in order not to cause the electronic component 60 to rapidly advance toward the flat surface 212, it is preferable to gradually reduce the pressure to generate a negative pressure.

Then, as shown in (b) of FIG. 10, the push rod 23 and the top portion 21 are lowered toward the mounting table 22 at an equal speed. Moreover, the area where the part has been embedded in the frame 62 of the sheet 67 contacts the adhesive sheet 64 on the cooling plate 63. Further, the top portion 21 is moved toward the mounting table 22, whereby the region of the frame 62 is adhered to the adhesive sheet 64. At this stage, the negative pressure of the top portion 21 is maintained, and the part-embedded sheet 67 is attracted to the flat surface 212 of the top portion 21, so that the part arrangement region 615 is not in contact with the adhesive sheet 64.

Here, when a negative pressure is not generated in the top portion 21, the part embedded in the sheet 67 contacts the adhesive sheet 64 in the presence of air. Thus, there is a fear that air bubbles enter the part that has been buried between the sheet 67 and the adhesive sheet 64. When the air bubbles enter, the heat transfer area reaching the cooling plate 63 is reduced, and the heat radiation effect of the electronic component 60 at the time of film formation is lowered. However, in the board mounting portion 2, in the presence of air, the component-embedded sheet 67 is raised in a direction away from the adhesive sheet 64, so that entry of air bubbles is prevented.

When the frame 62 is in close contact with the adhesive sheet 64, the non-adhesive surface 612 of the protective sheet 61 and the adhesive sheet 64 side of the cooling plate 63 are sealed in the sealed space 24b formed by the protective sheet 61, the cooling plate 63, and the frame 62. When the sealed space 24b is formed, as shown in (c) of FIG. 10, a negative pressure is also generated in the mounting table 22 while maintaining the negative pressure of the top portion 21. The airtight space 632 of the cooling plate 63 and the air hole 632 of the adhesive sheet 64 are decompressed to the sealed space 24b between the cooling plate 63 provided with the adhesive sheet 64 and the protective sheet 61. At this time, the negative pressure generated in the mounting table 22 is a negative pressure which is slightly closer to the atmospheric pressure than the negative pressure generated in the top portion 21, and is preferably set to a size capable of maintaining the adsorption of the electronic component 60 to the top portion 21.

When the pressure reduction of the sealed space 24b between the cooling plate 63 provided with the adhesive sheet 64 and the protective sheet 61 is completed, as shown in FIG. 10(d), while maintaining the negative pressure of the mounting table 22, The negative pressure of the top portion 21 gradually changes to a positive pressure. The part-embedded sheet 67 is slowly sucked and lowered toward the adhesive sheet 64. Further, the part-embedded sheet 67 is pressed downward, and the part-embedded sheet 67 is pressed against the adhesive sheet 64 adhered to the cooling plate 63. Further, the component-embedded sheet 67 is attached to the cooling plate 63 via the adhesive sheet 64.

Finally, as shown in (e) of FIG. 10, the top portion 21 is moved so as to be separated from the mounting table 22, thereby releasing the clip in which the component embedded sheet 67 is overlapped with the adhesive sheet 64 and the cooling plate 63. In. Thereby, the production of the component mounting board 68 including the electronic component 60, the protective sheet 61, the adhesive sheet 64, and the cooling plate 63 is completed. Further, the positive pressure generated in the top portion 21 and the negative pressure generated in the mounting table 22 may be released during the period in which the top portion 21 is separated from the mounting table 22.

In other words, the top portion 21, the push rod 23, and the mounting table 22 are driving portions that allow the component-embedded sheet 67 to approach the cooling plate 63. The top portion 21 and the mounting table 22 are fixed portions that sandwich the component embedded sheet 67 and the cooling plate 63, and also serve as a pressing portion that presses the frame 62 and the cooling plate 63 to closely contact the both. Further, the air pressure supply hole 223 of the mounting table 22 serves as a pressure reducing portion that decompresses the sealed space 24b between the component embedded sheet 67 and the cooling plate 63. Further, the air hole 213 of the top portion 21 serves as a pressure reducing portion that decompresses the flat surface 212 of the top portion 21 and the sealed space 24a between the parts embedded in the sheet 67.

The flat surface 212 of the top portion 21 serves as a partition member and a pressing member which cause a negative pressure to be generated before the component is embedded between the sheet 67 and the cooling plate 63, thereby preventing the bubble from entering the part and being buried. Between the entrance sheet 67 and the cooling plate 63, the pressing member interacts with the suction of the negative pressure by the mounting table 22 by the positive pressure, so that the component embedded sheet 67 is in close contact with the cooling plate 63. Further, the mounting table 22 serves as an adsorption member that interacts with the pressing of the positive pressure by the top portion 21 by the negative pressure to cause the component embedded in the sheet 67 to be in close contact with the cooling plate 63.

In this manner, the board mounting portion 2 adheres the protective sheet 61 of the electrode 602 in which the electronic component 60 is embedded to the cooling plate 63. This board mounting portion 2 has a pressure reducing portion that decompresses a space between the component array region 615 and the cooling plate 63. Then, after the pressure reduction by the pressure reducing portion, the protective sheet 61 and the cooling plate 63 are pressed against each other. Thereby, the air bubbles do not enter between the protective sheet 61 and the cooling plate 63, and the heat transfer area toward the cooling plate 63 can be sufficiently ensured.

Further, the board mounting portion 2 has air on the flat surface 212 of the top portion 21, that is, on the side opposite to the cooling plate 63 via the protective sheet 61, and the air that sucks the protective sheet 61 by the negative pressure to separate the cooling plate 63 from the protective sheet 61. Hole 213. This air hole 213 maintains a negative pressure until the decompression between the piece 67 and the cooling plate 63 in which the parts of the pressure reducing portion are buried is completed. Thereby, the situation in which the protective sheet 61 and the cooling plate 63 are adhered in a state where the pressure reduction is not completed can be prevented, and the fear that the air bubbles enter between the protective sheet 61 and the cooling plate 63 can be further reduced, and the cooling plate 63 can be sufficiently ensured. Heat transfer area.

Further, the air hole 213 opened in the flat surface 212 of the top portion 21 is lowered from the push rod 23 and the top portion 21 is placed on the mounting table 22 via the frame 62 in which the component has been embedded in the sheet 67, that is, the piece has been embedded from the part. Before the cooling plate 63 is approached, the negative pressure is generated at the latest before the space between the cooling plate 63 provided with the adhesive sheet 64 and the protective sheet 61 is formed. Thereby, it is possible to prevent the protective sheet 61 from being affixed to the cooling plate 63 before the pusher 23 provided with the protective sheet 61 (the part has been embedded in the sheet 67) starts to fall.

In addition, the board mounting portion 2 has a flat surface 212 of the top portion 21. The flat surface 212 is located on the opposite side of the protective sheet 61 from the cooling plate 63 and faces the electronic component 60. The air hole 213 which separates the cooling plate 63 from the protective sheet 61 before the end of the decompression between the part embedded plate 67 and the cooling plate 63 is opened on this flat surface 212. Thereby, the protective sheet 61 is not bent and flexed due to the pressure difference of the front and back of the protective sheet 61 during the depressurization, so that the protective sheet 61 can be flattened, and the electronic component 60 can be prevented from being protected during the board mounting process. The state of peeling off the sheet 61.

The air hole 213 on the side of the top portion 21 is converted from a negative pressure to a positive pressure after the component has been decompressed between the sheet 67 and the cooling plate 63, and the protective sheet 61 is pressed toward the cooling plate 63. In other words, the air hole 213 also serves as a partitioning portion between the protective sheet 61 and the cooling plate 63, a pressure reducing portion, and a pressing member for the protective sheet 61 and the cooling plate 63. However, isolation, decompression, and the function of the close-contact members can also be achieved by separate air holes.

For example, an air hole 632 is first provided on the cooling plate 63 as in the present embodiment. The board mounting portion 2 has a mounting table 22 on which the cooling plate 63 is placed and a negative pressure is generated. Further, the protective sheet 61 may be attracted to the cooling plate 63 by the mounting table 22 on which the cooling plate 63 is placed and the air holes 632 of the cooling plate 63.

Further, the action mechanism of the top portion 21 and the action mechanism of the push rod 23 may be any well-known mechanism, and the present invention is not limited by the mechanism of the mechanism.

For example, a ball screw that extends the shaft in the direction from the top portion 21 toward the mounting table 22 and a rail guide that extends in the direction from the top portion 21 toward the mounting table 22 are connected to the top portion 21. In this case, the top portion 21 moves toward the mounting table 22 along the guide rail in accordance with the direction of rotation of the screw shaft. The ball screw and the rail guide are extended so that the top portion 21 approaches the distance from the mounting table 22 to the thickness H1 of the frame 62 in which the component has been embedded in the sheet 67.

In addition, the rear end portion of the push rod 23 becomes a cam follower. The cam follower is driven on the circumferential surface of the oval cam. The camshaft is supported on the rotary motor and is rotatable in the circumferential direction. When the rotary motor is driven and the cam rotates, the cam follower raises the bulging portion of the cam, and the push rod 23 is pushed up.

Further, the method of forming the sealed space 24a and the sealed space 24b may be formed by the top portion 21 and the mounting table 22 without the component embedded in the sheet 67 and the cooling plate 63 as a component of the forming member. For example, one or both of the top portion 21 and the mounting table 22 may be cup-shaped, and may be housed in a space formed by the top portion 21 and the mounting table 22 so that the component is embedded in the sheet 67 and the cooling plate 63. Further, the front and back of the part-embedded sheet 67 are divided by the top portion 21 and the mounting table 22. However, in this case, the top portion 21 is desirably a flat surface 212 that surrounds the opening of the air hole 213 and extends toward the side wall of the mounting table 22. This side wall is in close contact with the flat surface of the mounting table 22 to form a closed space. The O-ring 215 is first placed on the end face of the side wall.

(Film Forming Process Unit) Next, the film forming process unit 3 that is responsible for the film forming step will be described. 11A and 11B are schematic views showing the configuration of the film formation processing unit 3. The film forming processing unit 3 forms an electromagnetic wave shielding film 605 on each of the electronic components 60 on the component mounting board 68 by sputtering. As shown in FIGS. 11A and 11B, the film forming processing unit 3 has a chamber 31 and a load-lock chamber 32. The chamber 31 is a cylindrical vacuum chamber that is expanded toward the radial direction in the axial direction. The chamber 31 is partitioned into a plurality of fan-shaped regions by a partition portion 33 extending in the radial direction. The processing position 311 and the film forming position 312 are distributed in a part of the fan-shaped area.

The partition portion 33 extends from the top surface of the chamber 31 toward the bottom surface, but does not reach the bottom surface. A rotary table 34 is provided in a space on the bottom side of the partitionless portion 33. The turntable 34 has a disk shape coaxial with the chamber 31 and rotates in the circumferential direction. The component mounting plate 68 that has been inserted into the chamber 31 from the sampling chamber 32 is placed on the turntable 34, and is rotated around the circumferential path to surround the processing position 311 and the film forming position 312.

Further, in order to maintain the position of the component mounting plate 68 with respect to the turntable 34, the turntable 34 is provided with, for example, a holding member mounting plate 68 such as a groove, a hole, a projection, a jig, a holder, a mechanical chuck, or an adhesive chuck. Holding parts.

A surface treatment unit 35 is provided at the processing position 311. The surface treatment unit 35 introduces a process gas such as argon gas, and plasma-processes the process gas by application of a high-frequency voltage to generate electrons, ions, radicals, and the like. For example, the surface treatment unit 35 is a cylindrical electrode that is opened on the side of the turntable 34, and a high-frequency voltage is applied by a radio frequency (RF) power source.

A target 361 constituting the sputtering source 36 is provided at the film formation position 312, and a sputtering gas as an inert gas such as argon gas is introduced. The sputtering source 36 applies electric power to the target 361, plasma-sputters the sputtering gas, and causes the generated ions or the like to collide with the target to produce particles. The target 361 contains a material of the electromagnetic wave shielding film 605. That is, the particles of the electromagnetic wave shielding film 605 are ejected from the target 361, and the particles of the electromagnetic wave shielding film 605 that have been printed are deposited on the electronic component 60 on the turntable 34.

The film formation position 312 is provided, for example, at two locations. The target material of each film formation position 312 may be the same material, or may be formed of a different material to form a laminated electromagnetic wave shielding film 605. A power source that applies electric power to the sputtering source 36 of each film formation position 312 can be applied, for example, to a well-known power source such as a direct current (DC) power source, a DC pulse power source, or an RF power source. Further, a power source for applying electric power to the sputtering source 36 may be provided for each sputtering source 36, or may be used by switching a common power source by a switch.

In the film formation processing unit 3, the electronic component 60 is etched or the surface of the ashing surface is cleaned and roughened at the processing position 311, and the adhesion of the electromagnetic wave shielding film 605 to the electronic component 60 is improved. The particles of the target 361 are deposited on the electronic component 60 at the film formation position 312, whereby the electromagnetic wave shielding film 605 is formed on the electronic component 60. The electrode 602 is embedded in the protective sheet 61, and the electrode exposed surface 601 is in close contact with the protective sheet 61. Therefore, the particles of the electromagnetic wave shielding film 605 are prevented from adhering to the electrode 602, and the particles of the electromagnetic wave shielding film 605 are prevented from entering the electrode exposed surface 601 and Between the protective sheets 61. Further, the heat of the electronic component 60 is conducted to the cooling plate 63, and excessive heat storage of the electronic component 60 is suppressed.

Further, the film formation processing unit 3 is a film formation method on the electronic component 60 by a sputtering method, but the film formation method is not limited thereto. For example, the film formation processing unit 3 may form the electromagnetic wave shielding film 605 on the electronic component 60 by vapor deposition, spraying, coating, or the like.

(Board Release Portion) Next, the board release unit 4 that performs the board release step will be described. FIG. 12 is a schematic view showing the configuration of the plate releasing portion 4. After the electromagnetic wave shielding film 605 is formed, the component mounting plate 68 is put into the board releasing portion 4. As a first step for obtaining each electronic component 60, the board releasing portion 4 peels off the component embedded sheet 67 from the cooling plate 63.

As shown in FIG. 12, the board releasing portion 4 includes a top portion 41 and a mounting table 42. The top portion 41 is disposed to face the mounting table 42. The position of the mounting table 42 does not move. On the other hand, the top portion 41 can be raised and lowered with respect to the mounting table 42. The top portion 41 is at least close to the distance H1 of the frame 62 of the mounting table 42 to the component mounting plate 68.

The top portion 41 is a block having an internal space 411, and has a flat surface 412 on a surface facing the mounting table 42. The mounting table 42 has a bottomed cup shape with the opening 421 facing the top portion 41. The flat surface 412 of the top portion 41 has the same size and shape as the component mounting plate 68 or is wider than the component mounting plate 68. On the other hand, the opening 421 of the mounting table 42 has an area including the part arrangement area 615 and the middle frame area 614 or less. The edge portion 422 of the mounting opening 42 around the opening 421 has a width greater than or equal to the width of the frame 62.

In this mounting table 42, the edge portion 422 supports the component mounting plate 68, and the opening 421 is closed by the component mounting plate 68. The side of the cooling plate 63 abuts on the edge portion 422. A gas pressure supply hole 423 is formed in the bottom of the mounting table 42. The air pressure supply hole 423 is connected to a pneumatic circuit 75 including a compressor, a negative pressure supply pipe, and the like outside the drawing. Therefore, a positive pressure is generated in the air hole 632 of the component mounting plate 68 placed on the opening 421.

Further, a push rod insertion hole 424 penetrating the mounting table 42 is formed in the edge portion 422 of the mounting table 42. The positioning position of the push rod insertion hole 424 is the same as the push rod insertion hole 631 of the cooling plate 63. When the component mounting plate 68 is placed on one side, the guide insertion hole 621 of the frame 62 is avoided. The position where the frame 62 is blocked. The push rod 43 is inserted in this push rod insertion hole 424. The push rod 43 is moved in the axial direction so that the front end can protrude toward a position higher than the frame 62 of the component mounting plate 68 that has been placed on the mounting table 42.

The pusher 43 peels off the component mounting plate 68 from the cooling plate 63 against the adhesive force of the adhesive sheet 64, and isolates the component mounting plate 68 from the cooling plate 63, and can lift and support the component mounting plate 68 in parallel. Set the stiffness, quantity and position relationship. For example, if the outer shape of the frame 62 is rectangular, it is arranged as a rod corresponding to each corner of the frame 62. The push rod insertion holes 424 are also provided corresponding to the number and positional relationship of the push rods 43.

Further, a pair of holding blocks 44 are disposed on both sides of the mounting table 42. The clamp block 44 only sandwiches the cooling plate 63 in the component mounting plate 68 placed on the mounting table 42. That is, the pair of holding blocks 44 are disposed at the same height as the cooling plate 63 placed on the mounting table 42, and have the same thickness as the cooling plate 63. Further, the holding blocks 44 can be brought into contact with each other and separated from each other around the cooling plate 63. However, the clamping block 44 does not move in the direction in which the top portion 41 and the mounting table 42 are aligned.

In turn, a plurality of air holes 413 leading to the inner space 411 are disposed on the flat surface 412 of the top portion 41. The air hole 413 is disposed in the same range and shape as the inner side of the frame 62 of the protective sheet 61, or at least the same size and shape as the part arrangement area 615. When the component mounting plate 68 has been placed on the mounting table 42, the position of the air hole 413 is the position covered by the component arrangement region 615.

In the internal space 411 of the top portion 41, a gas pressure supply hole 414 is formed in a portion different from the flat surface 412. The air pressure supply hole 414 is connected to a pneumatic circuit 75 including a compressor, a negative pressure supply pipe, and the like outside the drawing. Therefore, a negative pressure is generated in the air hole 413 through the air pressure supply hole 414 and the internal space 411.

Further, on the flat surface 412 of the top portion 41, an O-ring 415 that surrounds the air hole 413 is provided along the frame 62 of the component mounting plate 68 placed on the mounting table 42.

(a) to (e) of FIG. 13 show the flow of the operation of the board releasing portion 4. (a) to (e) of Fig. 13 are diagrams schematically showing transitions of the state of the board releasing portion 4 in each step. First, as shown in FIG. 13(a), the top portion 41 is separated from the mounting table 42, and the pusher 43 is first buried in the push rod insertion hole 424 of the mounting table 42. Then, the component mounting plate 68 is placed on the mounting table 42. When the component mounting plate 68 is placed, the cooling plate 63 is first fixed by the clamping block 44.

Then, as shown in FIG. 13(b), the top portion 41 is lowered toward the mounting table 42, and the flat surface 412 of the top portion 41 is brought into contact with the frame 62 of the component mounting plate 68. At this time, the height H1 from the surface of the part arrangement area 615 to the upper surface of the frame 62 is higher than the height H2 from the surface of the part arrangement area 615 to the top surface 603 of the electronic component 60. Thus, when the frame 62 has been clamped, the top surface 603 of the electronic component 60 does not reach the flat surface 412 of the top portion 41. Therefore, at least the part arrangement region 615 is enclosed in the sealed space 45 formed by the top portion 41, the protective sheet 61 and the frame 62 and sealed by the O-ring 415.

When the part arrangement area 615 is sealed in the sealed space 45, as shown in (c) of FIG. 13, a negative pressure is generated in the top portion 41, and a positive pressure is generated in the mounting table 42. Thereby, the force that is sucked upward toward the flat surface 412 of the top portion 41 and the force that is pushed upward from the mounting table 42 and pushed upward toward the flat surface 412 facing the top portion 41 act on the component array region 615 inside the frame 62. By this upper suction force and upper thrust force, a force sufficient to peel the part arrangement region 615 from the cooling plate 63 acts on the part arrangement area 615, and the part arrangement area 615 is peeled off from the cooling plate 63.

At the point of time when the part arrangement area 615 is peeled off, the protective sheet 61 is flat without strain, so that the momentum of the part arrangement area 615 toward the flat surface 412 of the top portion 41 is small, and the electronic component 60 is prevented from peeling off from the protective sheet 61, or the electronic component 60 The situation of flying out of the protective sheet 61. In the event that the part arrangement area 615 is rapidly peeled off, the flat surface 412 of the top portion 41 is also controlled, and the electronic component 60 is blocked by the flat surface 412, so that the electronic component 60 peels off from the protective sheet 61 or falls off from the protective sheet 61. cut back.

In order to further improve the effect of reducing the fear of peeling or peeling off of the electronic component 60 from the protective sheet 61, it is preferable that the top surface 603 of the electronic component 60 and the flat surface 412 are in a state before the protective sheet 61 is peeled off from the cooling plate 63. The interval is extremely small. Therefore, the interval between the top surface 603 and the flat surface 412 of the electronic component 60 is preferably set to a minimum necessary interval for peeling off the protective sheet 61 from the cooling plate 63. Further, it is also possible to gradually increase the air hole 632 that acts on the positive pressure with respect to the plurality of air holes 632 of the cooling plate 63, for example, the air hole 632 that functions as a positive pressure from the side of the cooling plate 63. In a manner in which the end portion on the other side is increased, the space in the opening 421 of the mounting table 42 is divided into a plurality of spaces or the like, and a plurality of systems for generating positive pressure are provided. With this arrangement, it is possible to prevent the part arrangement region 615 from being peeled off from the cooling plate 63 at once, and it is possible to suppress the electronic component 60 from rapidly protruding toward the flat surface 412 of the top portion 41.

Further, when the component arrangement region 615 is peeled off, the electronic component 60 abuts on the flat surface 412 of the top portion 41, and only the middle frame region 614 of the protective sheet 61 is deflected, and at least the component arrangement region 615 is maintained flat. In other words, if the flat surface 412 of the top portion 41 does not exist, the protective sheet 61 is bent in such a manner as to be curved with air therein. Then, there is a concern that the electronic component 60 is peeled off from the protective sheet 61, but the component arrangement region 615 is maintained in a flat shape, so that the peeling of the electronic component 60 is suppressed.

When the part arrangement area 615 is peeled off from the cooling plate 63, the push rod 43 is passed through the push rod insertion hole 424 of the mounting table 42 and the push rod insertion hole 631 of the cooling plate 63 as shown in (d) of FIG. And the push rod insertion hole 631 of the adhesive sheet 64 contacts the frame 62. Further, the push rod 43 is further advanced while the top portion 41 is separated from the mounting table 42 at a speed equal to that of the push rod 43. Since the cooling plate 63 is held by the holding block 44 and is not moved, the outer frame region 613 to which the frame 62 is adhered is also peeled off from the cooling plate 63, and the entire protective sheet 61 is peeled off from the cooling plate 63. At this time, the positive pressure of the mounting table 42 and the negative pressure of the top portion 41 are maintained. Therefore, the part arrangement area 615 hangs down toward the cooling plate 63 due to its own weight, and the situation of reattachment is suppressed.

Finally, as shown in (e) of FIG. 13, the push rod 43 is stopped, and the top portion 41 is moved further apart from the mounting table 42, whereby the gripping of the part-embedded sheet 67 is released. The peeling of the protective sheet 61 from the cooling plate 63 is completed. Further, the positive pressure of the mounting table 42 and the negative pressure of the top portion 41 may be released during this period.

That is, the top portion 41 serves as a fixing portion that presses the frame 62 that is disengaged from the component arrangement region 615. Further, the air pressure supply hole 423 of the mounting table 42 serves as a positive pressure generating hole, and the component arrangement region 615 is pressurized by the air hole 632 of the cooling plate 63, and the component arrangement region 615 is cooled from the cooling plate 63 earlier than the frame 62. The peeling part is peeled off. The air hole 413 of the top portion 41 serves as a negative pressure generating hole, and serves as an attracting member that attracts the component arranging region 615 and assists in peeling off from the cooling plate 63.

In addition, the flat surface 412 of the top portion 41 serves as a blocking member for suppressing peeling or peeling of the electronic component 60 from the protective sheet 61 when the component arrangement region 615 is peeled off, and further, the protective sheet 61 is flattened to suppress the electronic component 60 from the protective sheet. The flattened part that peeled off on 61. The pusher 43 becomes an upper top member which is peeled off from the cooling plate 63 after the component arrangement region 615 has been peeled off.

As described above, after the film forming step, the plate releasing portion 4 removes the cooling plate 63. The plate releasing portion 4 includes a positive pressure generating hole that takes the air pressure supply hole 423 of the mounting table 42 as an example, and a fixing portion that takes the top portion 41 as an example. The positive pressure generating hole faces the cooling plate 63, is disposed within a range including the part arrangement region 615, and generates a positive pressure. The fixing portion first presses a portion of the protective sheet 61 that is detached from the component arranging region 615, such as the frame 62, during the period in which the positive pressure generating hole pressurizes the component arranging region 615, and the component arranging region 615 has been removed from the cooling plate 63. After leaving, release the pressure.

Thereby, the protective sheet 61 is kept flat when the part arrangement area 615 is peeled off, and thus the situation in which the part arrangement area 615 is jumped due to the return of the protective sheet 61 to a flat reaction is avoided. Therefore, the electronic component 60 is prevented from peeling off from the protective sheet 61 and falling off.

Further, the plate releasing portion 4 has a flat surface 412 of the top portion 41 that is separated from the protective sheet 61 on the side of the top portion 41, that is, on the side opposite to the cooling plate 63 via the protective sheet 61. This flat surface 412 first presses the swollen portion of the part arrangement area 615 during the period in which the part arrangement area 615 is pressurized. Thereby, the part arrangement area 615 is flattened to prevent the electronic component 60 from peeling off. In addition, in the event that the part arrangement area 615 jumps, the flat surface 412 also blocks the electronic component 60, so that the electronic component 60 can be further prevented from peeling off from the protective sheet 61 and falling off.

Further, the plate releasing portion 4 has a negative pressure generating hole that generates a negative pressure so as to face the protective sheet 61. As an example, an air hole 413 for generating a negative pressure is provided on the flat surface 412 of the top portion 41. This air hole 413 attracts the protective sheet 61 with the pressurization of the part arrangement area 615 by the air hole 632. Therefore, it is possible to help the protective sheet 61 to be peeled off from the cooling plate 63 by the pressurization of the part arrangement region 615, and it is difficult to cause a peeling error.

Further, the plate releasing portion 4 includes a push rod 43. After the part arrangement area 615 has been separated from the cooling plate 63, the pusher 43 advances in the cooling plate 63, and pushes up the pressed portion of the frame 62 or the like in a direction away from the cooling plate 63. Thereby, after the part arrangement area 615 has been peeled off, the entire protective sheet 61 can be peeled off. In addition, when the fixing portion having the top portion 41 as an example is released, it is only necessary to separate from the protective sheet 61 as the push rod 43 advances.

Further, the action mechanism of the top portion 41, the action mechanism of the clamp block 44, and the action mechanism of the push rod 43 may be any well-known mechanism, and the present invention is not limited by the mechanism of the mechanism.

For example, a ball screw that extends the shaft in the direction from the top portion 41 toward the mounting table 42 and a rail guide that extends in the direction from the top portion 41 toward the mounting table 42 are connected to the top portion 41. In this case, the top portion 41 moves toward the mounting table 42 along the guide rail in accordance with the direction of rotation of the screw shaft. The ball screw and the rail guide are extended so that the top portion 41 approaches the distance H1 of the frame 62 of the component mounting plate 68 from the mounting table 42.

Further, on the outer side of the holding block 44, the circumferential surface of the oval cam is individually abutted against the pair of holding blocks 44. The camshaft is supported on the rotary motor and is rotatable in the circumferential direction. When the rotary motor is driven, the cam rotates, and the bulging portion of the cam hits the clamp block 44, the clamp block 44 is pushed away in the direction of the cooling plate 63, and the cooling plate 63 is sandwiched.

In addition, the rear end portion of the push rod 43 becomes a cam follower. The cam follower is driven on the circumferential surface of the oval cam. The camshaft is supported on the rotary motor and is rotatable in the circumferential direction. When the rotary motor is driven and the cam rotates, the cam follower raises the bulging portion of the cam, and the push rod 43 is pushed up.

Further, the plate releasing portion 4 peels the protective sheet 61 from the cooling plate 63 by generating a positive pressure in the mounting table 42. The flat surface 412 of the top portion 41 is an additional function of flattening the peeled protective sheet 61, and the air hole 413 opened in the flat surface 412 of the top portion 41 is also an additional function to assist the pressurization by the mounting table 42. Therefore, as shown in FIG. 14, the top portion 41 may have a rectangular tube shape that abuts the opening edge against the frame 62, and the flat surface 412 is omitted. Further, as shown in FIG. 15, the air hole 413 may be omitted from the flat surface 412 of the top portion 41.

(Peeling Processing Unit) Finally, the peeling processing unit 5 that is responsible for the part peeling step will be described. FIG. 16 is a schematic view showing the configuration of the peeling treatment unit 5. The component-embedded sheet 67 from which the cooling plate 63 has been removed via the plate releasing portion 4 is placed in the peeling processing portion 5, and as a final stage, the respective electronic components 60 are peeled off from the protective sheet 61. Further, when the peeling treatment unit 5 has been separated from the film forming apparatus 7, it may be referred to as a peeling processing apparatus.

As shown in FIG. 16, the peeling processing unit 5 includes a mounting table 51 on which a component has been embedded, a gripper 52, and a protective sheet 61 that is continuously moved. The guide portion 53 catches the protective sheet 61. The end portion is used to manufacture the opportunity for the chuck 52 to hold the protective sheet 61; the sheet stopper portion 54 to manufacture the peeling base point of the protective sheet; and the part stopper portion 55 to prevent the electronic component 60 from floating upward.

The mounting table 51 has a flat surface 511 on which the component has been embedded in the sheet 67. The component is embedded in the sheet 67 so that the electronic component 60 faces the flat surface 511, and the top surface 603 of the electronic component 60 contacts the mounting surface, and the protective sheet 61 is placed upward. The flat surface 511 includes an anti-slip member having an adhesive force, and the blocking property of the electronic component 60 is improved. Further, the outer peripheral region of the flat surface 511 is obtained by subtracting the height H2 from the surface of the component array region 615 to the top surface 603 of the electronic component 60 from the height H1 from the surface of the component array region 615 to the end surface of the frame 62. The depth of the height is dug down a section to allow the frame 62 to enter, and the electronic component 60 is placed on the flat surface 511 while the protective sheet 61 is maintained flat.

This mounting table 51 is a block having an internal space 512. On the flat surface 511 of the mounting table 51, a plurality of air holes 513 are formed in a region opposed to the component array region 615. The air hole 513 communicates with the internal space 512 of the mounting table 51. In the internal space 512 of the mounting table 51, a gas pressure supply hole 514 is formed in a portion different from the flat surface 511. The air pressure supply hole 514 is connected to a pneumatic circuit 75 including a compressor, a negative pressure supply pipe, and the like outside the drawing. Therefore, a negative pressure is generated in the air hole 513 through the air pressure supply hole 514 and the internal space 512. When the component-embedded sheet 67 has been placed, a guide insertion hole 515 that coincides with the guide insertion hole 621 of the frame 62 is provided at the edge of the mounting table 51.

The chuck 52 is a pair of blocks that face the grip faces. A pair of blocks can be contacted and separated. The chuck 52 is supported by a moving device movable in the horizontal direction and the vertical direction, and continuously moves at an angle of attack of 45 degrees with respect to the flat surface 511 along the protective sheet 61 placed on the flat surface 511 of the mounting table 51. In other words, the chuck 52 moves away from the mounting table 51 while being vertically moved on the flat surface 511 of the mounting table 51. The so-called continuous movement means that the stop is not included in the middle, and it is desirable to move at a constant speed. The movement of the collet 52 ranges from the end of the protective sheet 61 where the gripping opportunity has been produced to the opposite end of the end portion. The longitudinal moving direction of the collet 52 is the direction from the end of the protective sheet 61 to which the gripping opportunity has been produced to the opposite end of the end portion. For example, as shown in FIG. 17, the direction is the direction of the protective sheet 61 from the end portion of the frame 62 on the side of the guide insertion hole 621 to the opposite end of the end portion.

The sheet stopper portion 54 is a roller having a cylindrical shape that traverses the long axis of one side of the protective sheet 61 and is rotatable. This transverse direction is a direction orthogonal to the moving direction of the collet 52 (refer to FIG. 17). This sheet stopper portion 54 may be formed of a metal such as stainless steel. Further, when the length of the transverse protection sheet 61 is about 200 mm to 300 mm, the diameter of the sheet stopper portion 54 can be set to 5 mm to several ten mm. In the present embodiment, a cylindrical body made of stainless steel having a diameter of 6 mm is used.

The sheet stopper portion 54 is fixed to the height of the flat surface 511 of the mounting table 51, and is held directly below the chuck 52, and is placed on the mounting table 51 in a direction orthogonal to the long axis. Move up and down. The height of the sheet stopper portion 54 is set to match the height obtained by combining the electronic component 60 other than the electrode 602 and the protective sheet 61. That is, the sheet stopper portion 54 moves while pressing the non-adhesive surface 612 of the protective sheet 61. The degree of pressing is set to the extent that the electrode 602 is not damaged, or the electrode 602 is not rubbed, or the electrode 602 is not crushed. The movement range of the sheet stopper portion 54 is such that the edge of the guide portion 53, that is, the edge of the guide portion insertion hole 621 of the frame 62 is set as the base point until the opposite end of the protective sheet 61.

The part stopper portion 55 is a roller having a cylindrical shape that crosses the entire length of at least the entire region 615 of the protective sheet 61 and is rotatable. The part stopper 55 may be formed of a metal such as stainless steel. The diameter of the part stopper portion 55 may be determined in consideration of the diameter of the sheet stopper portion 54 and the size of the electronic component 60. However, if the diameter is smaller than the sheet stopper portion 54, the sheet can be closer to the sheet. The moving portion 54 is configured. In the present embodiment, a cylindrical body made of stainless steel having the same diameter as the sheet stopper portion 54 is used.

The component stopper 55 is disposed in proximity to and separated from the sheet stopper 54. While the chuck 52 and the sheet stopper 54 are vertically moved on the mounting table 51, the component stopper 55 is kept at a constant distance from the sheet stopper 54 to follow. The fixed distance is less than the length of the electronic component 60 adhered to the protective sheet 61 (the length in the moving direction of the component stopper 55). When the chuck 52 and the sheet stopper 54 are located at the end of the mounting table 51, the component stopper 55 is held at a distance from the sheet stopper 54 so as to be located opposite to the other via the guide insertion hole 621.

The guide portion 53 is disposed at the same position as the axis of the guide portion insertion hole 621 of the frame 62. The guide portion 53 is disposed in the guide portion insertion hole 515, and its front end faces the guide portion insertion hole 621 of the frame 62. The guide portion 53 is movable in the axial direction, protrudes toward the end of the protective sheet 61, and faces the end of the protective sheet 61 toward the collet 52, before the end of the protective sheet 61 reaches the collet 52, at the frame 62 The guide portion is advanced in the insertion hole 621. This guide portion 53 peels off one side of the protective sheet 61 by the top. Therefore, the guide insertion hole 621 has a pin shape and is provided at a plurality of locations along one side of the protective sheet 61.

For example, as shown in FIG. 17, the extending position of the guide insertion hole 621 is a position that is equally spaced apart from the center of one side of the frame 62. The guide portion 53 is provided corresponding to the guide insertion hole 621, and the guide portion 53 is formed in a round bar shape. Then, the chuck 52 and the sheet stopper 54 are longitudinally moved in a direction orthogonal to one side of the frame 62, and the electronic component 60 is peeled off from the protective sheet 61.

(a) to (f) of FIG. 18 show the flow of the operation of the peeling processing unit 5. (a) to (f) of FIG. 18 are transition diagrams schematically showing the state of the peeling processing unit 5 in each step. First, as shown in FIG. 18(a), in a state where the top surface 603 of the electronic component 60 is brought into contact with the flat surface 511, the component embedded sheet 67 is placed on the mounting table 51. In other words, between the plate releasing portion 4 and the peeling processing portion 5, a reversing device for vertically inverting the component-embedded sheet 67 separated from the cooling plate 63 in the plate releasing portion 4 is provided, and the component has been replaced. The buried sheet 67 is downloaded and placed on the mounting table 51 in a state where it has been reversed. The negative pressure is generated in the air hole 513 of the mounting table 51, and the electronic component 60 is first attracted to the flat surface 511. The sheet stopper portion 54 is moved to the edge of the guide portion insertion hole 621 of the frame 62, and the chuck 52 is first positioned directly above the guide portion insertion hole 621 of the frame 62. The part stopper portion 55 is first opened at a distance from the sheet stopper portion 54, and the component stopper portion 55 is first positioned outside the guide portion insertion hole 621 of the frame 62.

As shown in (b) of FIG. 18, the guide portion 53 is moved to the upper side in the axial direction. The guide portion 53 moves in the guide insertion hole 621 of the frame 62 and reaches the end of the protective sheet 61 adhered to the frame 62. The guide portion 53 is further advanced to protrude the end portion of the protective sheet 61 in a direction away from the frame 62. Thereby, the end portion of the protective sheet 61 starts to peel off due to the guide portion 53. When the guide portion 53 further advances, the end portion of the protective sheet 61 is sandwiched by the guide portion 53 and the sheet stopper portion 54 and guided toward the chuck 52. Further, when the end portion of the protective sheet 61 is being guided by the guide portion 53, the chuck 52 can also move toward the end portion of the protective sheet 61 to greet the end portion of the protective sheet 61.

As shown in (c) of FIG. 18, when the end of the protective sheet 61 reaches the chuck 52, the pair of blocks are closed, and the end of the protective sheet 61 is gripped by the chuck 52. When the chuck 52 grips the end portion of the protective sheet 61, as shown in FIG. 18(d), the guide portion 53 is buried in the guide portion insertion hole 621 of the frame 62, and the component stopper portion 55 is moved. And the part stopper portion 55 and the sheet stopper portion 54 are brought close to a distance that is less than the length of the electronic component 60.

As shown in (e) of Fig. 18, the chuck 52 and the sheet stopper portion 54 are moved along the protective sheet 61, and the chuck 52 is lifted. The end portion of the protective sheet 61 is held by the chuck 52, and the sheet stopper portion 54 is moved on the protective sheet 61. Therefore, the protective sheet 61 is lifted by the chuck 52 with the sheet stopper portion 54 as a base point, and the electronic component 60 is peeled off from the protective sheet 61 with the sheet stopper 54 as a base point. In the case where the peeled protective sheet 61 is kept in a vertical state and peeled off, for example, the horizontal movement of the chuck 52 and the speed component of the vertical movement may be kept the same. If the horizontal movement is the same as the vertical movement speed component, even if the movement speed is changed, the separation can be continuously performed without stopping, as long as the movement speed does not stop, but the movement speed of the horizontal movement and the vertical movement is preferably maintained at a constant speed.

At this time, as shown in FIG. 19, when the peeling of the electronic component 60 from the protective sheet 61 is performed, only the end portion of the electronic component 60 is sandwiched by the sheet stopper portion 54 and the flat surface 511 of the mounting table 51. In the state, the electronic component 60 is to be floated in such a manner as to lift the peeling start end 60a. However, the part stopper 55 follows the sheet stopper 54. This part stopper portion 55 presses the side of the peeling start end 60a to be lifted up. Therefore, the floating of the electronic component 60 is prevented, the gap 94 between the electrode 602 which has been peeled off from the protective sheet 61 and the protective sheet 61 continues to exist, and the electronic component 60 is not attached again, but is maintained on the flat surface of the mounting table 51. 511. Further, since the sheet stopper portion 54 is a roller that can rotate the shaft, the electronic component 60 is rotated while being pressed, and the friction with the electronic component 60 is suppressed.

Further, the sheet stopper portion 54 moves while pressing the non-adhesive surface 612 of the protective sheet 61. Therefore, before the peeling of the electronic component 60 is started and the only end portion of the electronic component 60 in the peeling process is sandwiched by the sheet stopper portion 54 and the flat surface 511 of the mounting table 51, the sheet stopper is prevented from being stopped. The portion 54 also follows the protective sheet 61 from which the electronic component 60 has been peeled off. However, from the viewpoint of the function of producing the peeling base point by the sheet stopper portion 54, the sheet stopper portion 54 does not have to be moved while pressing the non-adhesive surface 612 of the protective sheet 61. That is, the sheet stopper portion 54 may be moved at a position slightly away from the protective sheet 61.

Further, as shown in (f) of FIG. 18, when the chuck 52 and the sheet stopper portion 54 have completely cut the part arrangement region 615 of the protective sheet 61, all the electronic components 60 are peeled off from the protective sheet 61. And arranged on the flat surface 511 of the mounting table 51. The formation of the electromagnetic wave shielding film 605 in the film forming apparatus 7 is completed by recycling the electronic component 60. Further, the chuck 52 cuts the flat surface 511 of the mounting table 51 and the angle of attack away from the mounting table 51 is not limited to 45 degrees. The position of the chuck 52 may be fixed, and the mounting table 51 may be continuously moved to peel off the protective sheet 61, and both the chuck 52 and the mounting table 51 may be movable. In other words, the chuck 52 and the mounting table 51 only need to move relative to each other.

FIG. 20 is a photograph obtained by photographing the electrode 602 after the electronic component 60 is peeled off from the protective sheet 61 by the peeling processing unit 5. According to the peeling treatment portion 5, the flatness of the protective sheet 61 is always maintained by the sheet stopper portion 54, and once the protective sheet 61 is peeled off, the protective sheet 61 can be prevented from returning to the electronic component 60 and being reattached. Further, the position of the electronic component 60 is fixed by the component stopper 55 and the air hole 513 of the mounting table 51, and it is also possible to prevent the protective sheet 61 from coming up again as if it is caught up again. As a result, as shown in FIG. 20, the residue of the protective sheet 61 is not seen on the electrode 602 of the electronic component 60.

As described above, after the film formation processing unit 3 is formed, the peeling processing unit 5 peels off the electronic component 60 from the protective sheet 61. The peeling treatment unit 5 includes a mounting table 51, a chuck 52, and a fixing portion that fixes the position of the electronic component 60. The mounting table 51 supports the electronic component 60 that has been adhered to the protective sheet 61. The chuck 52 grips the end portion of the protective sheet 61, relatively moves with respect to the mounting table 51, and continuously peels off toward the opposite end of the end portion. When the electronic component 60 is peeled off from the protective sheet 61, the fixing portion fixes the position of the electronic component 60. Thereby, the electronic component 60 and the protective sheet 61 are once again peeled off after being peeled off, and the residue 93 of the protective sheet 61 can be suppressed from occurring in the electronic component 60.

The fixing portion is, for example, a part stopper portion 55 or a flat surface 511 of the mounting table 51 through which the air holes 513 are formed. The part stopper portion 55 follows the sheet stopper portion 54 at a distance that is less than the length of the electronic component 60, and holds the electronic component 60 up and down. The mounting table 51 sucks the electronic component 60 and holds it up and down. However, the mounting table 51 does not have to be suctioned by the air holes 513 as long as it has a function as a fixing portion. For example, the mounting table 51 may be an adhesive chuck, an electrostatic chuck, or a mechanical chuck as long as the electronic component 60 can be fixed.

In addition, a guide portion 53 that protrudes toward the end of the protective sheet 61 is included. The chuck 52 is located at the protruding destination of the guide portion 53 before the end portion of the protective sheet 61 is gripped. Further, the guide portion 53 faces the collet 52, and guides the end portion of the protective sheet 61 toward the collet 52. Thereby, the opportunity for the chuck 52 to be gripped can be manufactured, and the possibility that the electronic component 60 and the protective sheet 61 are detached can be reduced.

Further, a sheet stopper portion 54 that moves along the protective sheet 61 together with the chuck 52 and produces a peeled base point is included. Further, the sheet stopper portion 54 is located in the vicinity of the projecting destination of the guide portion 53, and sandwiches the end portion of the protective sheet 61 from which the guide portion 53 has been peeled off together with the guide portion 53, and guides it toward the chuck 52. Thereby, the chuck 52 can grip the end portion of the protective sheet 61 more surely, and the possibility of detachment of the electronic component 60 and the protective sheet 61 can be reduced.

Further, the sheet stopper portion 54 has been described as an example of a cylindrical body having an axis orthogonal to the moving direction of the sheet stopper portion 54. However, the sheet stopper may be moved while pressing the protective sheet 61. It is a plate or a block. Further, the component stopper portion 55 has been described as an example of a cylindrical body having an axis orthogonal to the moving direction of the component stopper portion 55. However, a plate-shaped body, a block body, or a brush may be used. When the component stopper 55 is a cylindrical body, since it is a roller that can rotate the shaft, when the electronic component 60 is pressed, the rotation is performed, and the friction with the electronic component 60 is suppressed.

The operation mechanism of the chuck 52, the operation mechanism of the sheet stopper portion 54, the action mechanism of the component stopper portion 55, and the operation mechanism of the guide portion 53 may be any well-known mechanisms, and the present invention is not limited by the mechanism of the mechanism.

For example, the following action mechanism can be employed in the collet 52. That is, the two blocks are supported by the base, and the block on one side becomes positional with respect to the base. The block on the other side becomes movable with respect to the block on one side. The oval cam abuts on the outside of the movable block. If the cam is rotated and the block hangs over the long diameter range, the movable block is held by the cam and approaches the stationary block. Further, a compression spring is provided between the pair of blocks to bias the direction in which the distance between the pair of blocks is increased. When the cam is rotated and the block hangs within the short diameter range, the movable block becomes separated from the stationary block by the force applied by the compression spring.

Further, for example, a ball screw and a guide rail which are extended at an angle of 45 degrees with respect to the flat surface 511 of the mounting table 51 are disposed, and the base of the chuck 52 is fixed to the slider of the ball screw, and the guide rail is held. When the screw shaft of the ball screw is rotated by the motor, the chuck 52 moves from one end of the mounting table 51 to the other end along the guide rail.

Further, in the component stopper portion 55, the tension spring is interposed between the support member stopper portion 55 and the base of the sheet stopper portion 54, and the direction in which the component stopper portion 55 and the sheet stopper portion 54 are approached is applied. Forces, and an elliptical cam is disposed between the support member stopper portion 55 and the base of the sheet stopper portion 54 to resist the force applied by the tension spring in a state where the long diameter range of the cam abuts against the base. The force is applied in a direction in which the part stopper portion 55 is separated from the sheet stopper portion 54.

Further, the rear end portion of the guide portion 53 becomes a cam follower. The cam follower is driven on the circumferential surface of the oval cam. The camshaft is supported on the rotary motor and is rotatable in the circumferential direction. When the rotary motor is driven and the cam rotates, the cam follower raises the bulging portion of the cam, and the guide portion 53 is pushed up.

In addition, the position at which the guide insertion hole 621 is formed is a position that is equally spaced apart from the center of one side of the frame 62. Thereby, the entire side of the protective sheet 61 is easily peeled off. The guide portion 53 is provided corresponding to the guide insertion hole 621, and the guide portion 53 is formed in a round bar shape. Further, the chuck 52 and the sheet stopper 54 are longitudinally cut in a direction orthogonal to one side of the frame 62, and the electronic component 60 is peeled off from the protective sheet 61. The peeling treatment portion 5 is not limited thereto, and the guide portion insertion hole and the guide portion of various shapes may be employed, and the peeling direction may be various directions.

For example, as shown in FIG. 21, a guide portion 53 having a long rectangular cross section, an ellipse, a rectangle, or the like at the tip end along one side of the frame 62 may be employed. According to this guide portion 53, the range in which the protective sheet 61 protrudes is increased, so that the protective sheet 61 is easily rolled up, and the end portion of the protective sheet 61 easily reaches the chuck 52. Further, as shown in FIG. 22, a slit 622 including an arrangement region of the guide portion 53 may be formed in the frame 62 instead of the guide portion insertion hole 621. Further, as shown in FIG. 23, the guide portion insertion hole 621 may be disposed at a corner portion of the frame 62, and the corner portion of the frame 62 may be used as a peeling start point to cause the chuck 52 and the sheet stopper portion 54 to face each other. The angular movement is peeled off along the diagonal of the protective sheet 61.

(Release Processing Unit According to Another Embodiment) The peeling processing unit 5 of another embodiment will be described with reference to Figs. 24 to 27 . The same components and the same functions as those of the above-described embodiments are denoted by the same reference numerals, and detailed description thereof will be omitted, and only portions different from the above-described embodiments will be described.

Fig. 24 is a plan view showing the peeling treatment unit 5 of another embodiment. As shown in FIG. 24, the peeling processing unit 5 of the present embodiment includes a susceptor 80, a sheet supply stage 81, a stage 82, a mounting table 51, a chuck 52, a guide portion 53, and a discharge table 83, and the upper and lower sides of the chuck 52 are passed. The movement of the direction and the movement of the mounting table 51 in the horizontal direction peel the protective sheet 61. The susceptor 80 has a horizontal upper surface, and the members (81 to 83) are arranged in parallel in the region R on the susceptor 80.

The sheet supply stage 81 is a rectangular plate-like body having a mounting surface on which the component has been embedded in the sheet 67, and is configured to be vacuum-clampable. The part-embedded sheet 67 is a part in which the slit 622 is provided in the frame 62 as shown in FIG.

This sheet feeding table 81 is configured to be rotatable. Here, the sheet supply stage 81 is connected to a rotation mechanism 81a having a rotation shaft 811a parallel to one side thereof, and is rotated by 180° around the rotation shaft 811a. That is, the front and back of the sheet supply table 81 are reversed symmetrically with respect to this rotation axis 811a.

The stage 82 is a plate-shaped body placed on the mounting table 51, and is provided at a position facing the inverted sheet supply table 81. This stage 82 is configured to slide in a direction parallel to the rotation shaft 811a. Here, the stage 82 is connected to the drive unit 821, and the drive unit 821 is used as a drive source, and linearly moves along a pair of guides 822 provided in parallel with the rotation shaft 811a.

The mounting table 51 is placed on the stage 82 and held by a vacuum chuck. In this state, the platform 82 moves, so the mounting table 51 is fixed in position on the platform 82. The mounting table 51 has the same configuration as the mounting table 51 of the above-described embodiment, but is partially different. Hereinafter, different structures will be mainly described. That is, one end portion of the mounting table 51 is formed into a comb shape, and the comb-like portion is exposed from the stage 82 in a state where it has been placed on the stage 82. Here, in the state shown in FIG. 24, one end portion of the mounting table 51 is an end portion on the side opposite to the side where the chuck 52 is located. Further, the air pressure supply hole 514 is provided on the side surface of the mounting table 51 (see FIG. 27).

Further, the mounting table 51 is configured to be rotatable. Here, the mounting table 51 is rotatably and slidably coupled to a rotating mechanism 83a having a rotating shaft 833a parallel to the rotating shaft 811a. Specifically, a bearing is provided in the mounting table 51, and the rotating shaft 833a is inserted into the bearing. The stage 51 is rotated by 180° around the rotation shaft 833a, and the front and back are reversed symmetrically with respect to the rotation axis 833a. Further, the mounting table 51 moves linearly along with the stage 82 along the rotating shaft 833a. In other words, the rotation mechanism 83a has a drive unit that rotates the mounting table 51. However, the drive unit does not have a drive unit that linearly moves the mount 51, and the linear movement of the mount 51 is guided only by the rotary shaft 833a.

The discharge table 83 is a plate-like body for discharging electronic parts that have been peeled off from the protective sheet 61 in which the parts have been embedded in the sheet 67. A discharge tray 831 for recovering the electronic component 60 that has been peeled off from the protective sheet 61 of the component-embedded sheet 67 is placed on the discharge table 83, and the discharge tray 83 is configured to vacuum-hold the discharge tray 831. The discharge table 83 is formed one turn larger than the discharge tray 831. A cylindrical member 83b is provided in an outer peripheral region of the discharge table 83, that is, a region between the outer edge of the discharge tray 831 and the outer edge of the discharge table 83. Here, the tubular members 83b are erected on the four corners of the discharge table 83. The tubular member 83b has stretchability and sealing properties, and is configured to be decompressed by the inside of the cylinder. That is, the through hole is provided at the four corners of the discharge table 83, and the cylindrical member 83b is provided so that the through hole communicates with the inside of the cylinder. Specifically, the cylindrical member 83b is formed into a serpentine tube shape (see FIG. 27). In addition, the cylindrical member 83b is formed to be longer than the thickness of the discharge tray 831, and in a state where the discharge tray 831 has been placed on the discharge table 83, the front end surface is higher than the upper surface of the discharge tray 831.

The discharge table 83 is rotatably formed and disposed at a position opposed to the mounting table 51 on the stage 82. Here, the discharge stage 83 is connected to the rotation mechanism 83a, and is rotated by 180 degrees around the rotation shaft 833a, and the front and back are reversed symmetrically with respect to this rotation axis 833a. Further, the rotation mechanism 83a rotates the mounting table 51 and the discharge table 83, but is configured to be individually rotated by 180°. Further, the rotation mechanism 83a guides the mounting table 51 so as to be linearly moved, but only the discharge table 83 is rotated. Further, the rotation mechanism 83a that rotates the mounting table 51 and the discharge table 83 is not limited to a single rotation mechanism, and may be provided separately.

The sheet feeding table 81 and the discharge table 83 sandwich the guide 822 of the stage 82 and are arranged in a direction orthogonal to the moving direction of the stage 82. Here, a rectangular region in which the sheet supply table 81 and the discharge table 83 are disposed, that is, a rectangular region indicated by a broken line in FIG. 24 is referred to as a region R. The supply of the component-embedded sheet 67 from the sheet supply table 81 to the mounting table 51 and the discharge of the electronic component 60 from the mounting table 51 to the discharge table 83, which will be described later, are performed in this region R.

An opening 80a is provided in the base 80. This opening 80a is disposed at a position away from the region R in the moving region of the platform 82. Here, it is disposed in a central portion of the base 80.

The chuck 52 is disposed above the opening 80a and is raised and lowered in the up and down direction, that is, vertically raised and lowered with respect to the base 80. That is, the chuck 52 is provided with a lifting mechanism 521.

FIG. 25 is a partially enlarged perspective view of the peeling treatment portion 5 in which the end portion of the protective sheet 61 is gripped by the chuck 52. The chuck 52 includes a pair of plate-like members (52a, 52b), and one end portion of the protective sheet 61 is sandwiched between the pair of plate-like members (52a, 52b). In other words, the opposing faces on the distal end side of the pair of plate-like members (52a, 52b) serve as grip faces for holding the protective sheet 61. Moreover, the front end portion of the plate-like body 52b located on the side of the region R is formed into a comb shape. The pair of plate-like members (52a, 52b) are vertically disposed with respect to the base 80, and the plate-like body 52a on one side is fixedly disposed to maintain the state thereof, and the plate-like body 52b on the other side is rotated around the fulcrum like a pair of scissors. Thereby, it contacts and separates from the plate-shaped body 52a of one side.

The guide portion 53 is provided below the opening 80a, and passes through the opening 80a, and moves forward and backward obliquely with respect to the base 80 so as to be closer to the grip surface of the plate-like body 52a on the one side. The advancement and retreat of the guide portion 53 is performed by a drive mechanism (not shown). The guide portion 53 is a plate-like body in which the distal end portion is formed into a comb shape, and the distal end portion is disposed obliquely upward with respect to the base 80. The guide portion 53 forms the distal end portion so as to be in contact with the grip surface of the plate-like body 52a or slightly in contact with the rising end of the inclined forward and backward directions. The guide portion 53 is advanced obliquely upward through the opening 80a, and the convex portion forming the comb-like portion enters the concave portion of the mounting table 51 provided at the one end portion of the comb-like portion, and enters the formation of the plate-like body 52b. In the recess of the comb-like portion.

As shown in FIG. 24, a rotating mechanism 84 having a rotating shaft perpendicular to the base 80 is connected to the elevating mechanism 521. A rotating arm 85 for discharging the protective sheet 61 by the chuck 52 is provided on the rotating mechanism 84. A suction cup 85a is provided at the front end of the rotating arm 85. The rotating arm 85 is rotated by the rotating mechanism 84 to reciprocate between the recovery position shown in the drawing and the suction position of the protective sheet 61 as a position rotated horizontally by 180 from this position. At this suction position, the chuck 85a is opposed to the protective sheet 61 from which the electronic component 60 has been peeled off. Further, the plate-like bodies 86 are fixedly disposed in a relative manner in the opposing positions of the suction cups 85a at the suction positions.

The operation of the peeling treatment unit 5 having the above configuration will be described. First, the electronic component 60 is placed upward, and the protective sheet 61 is placed downward to mount the component embedded sheet 67 on the sheet supply table 81, and vacuum-clamped by the sheet supply table 81. Further, in the region R, the mounting table 51 is placed on the stage 82 such that one end of the comb is exposed from the platform 82.

In the state where vacuum clamping is performed as described above, the sheet supply stage 81 is rotated by the rotation mechanism 81a. By this rotation, the component-embedded sheet 67 is sandwiched by the sheet supply table 81 and the mounting table 51. At this time, rotation and clamping are performed so as not to give an impact to the electronic component 60. By this rotation and clamping, the one end portion of the protective sheet 61, that is, the slit 622 of the frame 62 in which the component has been embedded in the sheet 67 is located above the comb-shaped one end portion of the mounting table 51.

After the component has been embedded in the sheet 67, the vacuum chucking of the sheet supply table 81 is released, and the sheet supply table 81 is rotated by the rotation mechanism 81a to return to the original state. Further, a negative pressure is generated in the air hole 513 of the mounting table 51, and the electronic component 60 in which the component has been embedded in the sheet 67 is attracted to the flat surface 511. This adsorption is preferable in that the sheet feeding stage 81 is returned to the original state.

Then, the stage 82 on which the mounting table 51 is placed is linearly moved along the guide 822 toward the side where the opening 80a is provided by the driving portion 821, and the comb-shaped one end portion of the mounting table 51 is stopped at the position on the opening 80a. At this time, as shown in FIG. 25, the comb-shaped portion of the mounting table 51 faces the chuck 52 up and down.

In this state, first, the chuck 52 is lowered by the elevating mechanism. Further, similarly to the above-described embodiment, the sheet stopper portion 54 is moved directly below the collet 52, and the non-adhesive surface 612 of the protective sheet 61 is lightly pressed directly under the collet 52 (shown in FIG. 25). status).

Thereafter, the guide portion 53 is raised obliquely. When the guide portion 53 is raised, the component stopper portion 55 is retracted to a position where it does not come into contact with the guide portion 53 as in the above-described embodiment. The guide portion 53 advances obliquely upward through the opening 80a, whereby the comb-like convex portion of the distal end portion of the guide portion 53 enters the concave portion of the comb-forming portion of the mounting table 51 as shown in FIG. Further, the slit 622 of the frame 62 in which the component has been embedded in the sheet 67 is located above the comb-shaped one end portion of the mounting table 51, whereby one end portion of the protective sheet 61 is located above the comb-shaped one end portion of the mounting table 51. Therefore, one end portion of the protective sheet 61 is peeled off from the frame 62 by the front end portion of the guide portion 53 that is inclined upward, and the one end portion of the protective sheet 61 is rolled up with the sheet stopper portion 54 as a base point.

At this time, the front ends of the pair of plate-like members (52a, 52b) of the chuck 52 are opened, and one end portion of the rolled protective sheet 61 is obtained between the grip surface of the plate-like body 52a and the front end of the guide portion 53. Hold. Thereafter, the plate body 52b on the other side is closed. That is, the convex portion of the plate-like body 52b provided at the front end portion forming the comb-like portion corresponds to the concave portion of the guide portion 53 provided at the front end portion forming the comb-like portion, so that the convex portion enters the concave portion, in the plate One end portion of the protective sheet 61 is sandwiched between the front ends of the body 52a and the plate-like body 52b, thereby holding the protective sheet 61.

When the protective sheet 61 is gripped by the chuck 52, the guide portion 53 is inclined downward and retracted toward the lower side of the base 80. Further, the part stopper portion 55 moves from a position where contact with the guide portion 53 is avoided to a position at which the sheet stopper portion 54 becomes a fixed distance from the length of the electronic component 60 that is not full.

Then, the protective sheet 61 is peeled off. In other words, the chuck 52 is lifted by the elevating mechanism 521 while the one end portion of the protective sheet 61 has been gripped, and the stage 82 on which the mounting table 51 is placed moves along the guide 822 toward the region R side. At this time, the rise of the chuck 52 and the movement of the stage 82 are performed at the same speed and at a fixed speed without stopping. The operation at this time is performed in the same manner as the operations shown in (d) to (f) of FIG. 18 and FIG.

When the peeling of the protective sheet 61 is completed, the protective sheet 61 is opposed to the plate-shaped body 86. As shown in Fig. 26, the rotating arm 85 is rotated to the suction position by the rotating mechanism 84, and the protective sheet 61 is sandwiched by the suction cup 85a at the tip end of the rotating arm 85 and the plate-like body 86, and the protective sheet 61 is held by the suction cup 85a. . Concavities and convexities are provided on the surface of the plate-like body 86 opposed to the protective sheet 61, and the adhesive surface 611 of the protective sheet 61 is not adhered to the plate-like body 86. When the protective sheet 61 is held by the suction cup 85a, the grip by the chuck 52 is released.

After the protective sheet 61 is held, the rotating arm 85 is reversely rotated to return to the original position, that is, the recovery position. A recovery box (not shown) is provided below the collection position, and the protective sheet 61 is dropped into the collection box by releasing the holding of the protective sheet 61, and the protective sheet 61 is collected.

After the peeling of the protective sheet 61 is completed, the electronic component 60 that has been peeled off from the protective sheet 61 is suction-held on the mounting table 51, and the frame 62 is supported on the mounting table 51. Further, the mounting table 51 is located in the region R by the movement of the stage 82. In a state where the discharge tray 831 placed thereon is vacuum-held, the discharge table 83 is rotated around the rotation shaft 833a by the rotation mechanism 83a, and faces the mounting table 51.

Here, since the tubular member 83b is provided at the four corners of the discharge table 83, as shown in Fig. 27, the front end of the cylindrical member 83b is in contact with the mounting table 51, the discharge table 83 is opposed to the mounting table 51, and the discharge tray is discharged. The 831 is opposed to the frame 62 and the electronic component 60. At this time, on the mounting table 51, the portion where the frame 62 is placed is dug downward, and as shown, the upper surface of the frame 62 is at the same height as the upper surface (electrode exposed surface 601) of the electronic component 60.

In this state, the inside of the cylindrical member 83b is decompressed. When the inside of the serpentine tubular member 83b is depressurized, the tubular member 83b contracts, and the discharge table 83 approaches the mounting table 51. Thereby, the discharge tray 831 comes into contact with the frame 62 and the electronic component 60 on the mounting table 51. That is, the frame 62 and the electronic component 60 are sandwiched by the discharge tray 831 and the mounting table 51, and the position is fixed.

Thereafter, the discharge table 83 is rotated by 180° around the rotation shaft 833a by the rotation mechanism 83a, and returns to the original position. At this time, the pressure reduction inside the cylindrical member 83b is maintained, whereby the mounting table 51 is vacuum-held by the cylindrical member 83b. Therefore, the rotation mechanism 83a rotates the rotation of the mounting table 51 together with the discharge table 83. At the time of this rotation, since the frame 62 and the electronic component 60 are sandwiched by the discharge tray 831 and the mounting table 51, the positional displacement of the electronic component 60 by the rotation mechanism 83a can be suppressed.

After this rotation, the vacuum clamping of the mounting table 51 is released and becomes a positive pressure. Thereby, it is easy to transfer the electronic component 60 to the discharge tray 831. Further, the surface of the discharge tray 831 has adhesiveness, and the positional deviation of the electronic component 60 at the time of transfer can be suppressed. Then, the pressure reduction of the cylindrical member 83b is stopped. Thereafter, the mounting table 51 is rotated by 180° by the rotating mechanism 83a and returned to the stage 82. At this time, since the frame 62 is supported only by the mounting table 52, it remains on the discharge tray 831 together with the electronic component 60. Then, the vacuum chucking by the discharge tray 831 of the discharge table 83 is released, and the discharge tray 831 on which the electronic component 60 and the frame 62 are placed is conveyed by a conveyance mechanism (not shown). Thereby, one peeling operation is completed. In addition, the empty discharge tray 831 is transported by a transport mechanism (not shown), placed on the discharge table 83, and vacuum-clamped, and the component embedded in the sheet 67 is placed by a transport mechanism (not shown). On the sheet supply table 81, the next peeling operation is started.

As described above, the peeling treatment unit 5 of the present embodiment has the front end portion of the chuck 52 (the plate-shaped body 52b), the distal end portion of the guide portion 53, and the one end portion of the mounting table 51 in a comb shape to guide The portion 53 is raised obliquely, and the front end portion thereof passes through the concave portion of the comb portion at one end portion of the mounting table 51, and the protective sheet 61 is peeled off from the frame 62 and rolled up, and the guide portion 53 and the other side of the chuck 52 are separated. (plate body 52a) is clamped. Moreover, one side of the collet 52 is closed from this state. Thereby, the protective sheet 61 can be held more surely by the chuck 52.

In other words, in the shape of the guide portion 53 of the peeling treatment portion 5 of the embodiment, the upper top position of the guide portion 53 is restricted so that the guide portion 53 does not interfere with the chuck 52. Therefore, due to the flexibility of the protective sheet 61, there is a fear that the end portion of the protective sheet 61 that has been lifted upward is bent like the front end of the covering portion 53. In this state, there is a fear of holding failure of the protective sheet 61 by the chuck 52. On the other hand, in the peeling processing unit 5 of the other embodiment in which the guide portion 53 and the one side of the chuck 52 and the one end portion of the mounting table 52 are formed in a comb shape, the guide portion 53 can be raised to the chuck 52. Closer to the end. Further, the guide portion 53 is inclinedly raised, and the guide portion 53 is inclinedly advanced with respect to the other side of the collet 52. Therefore, the guide portion 53 in a state in which the protective sheet 61 has been wound up can bring the protective sheet 61 closer to the other of the chuck 52. The side grip surface presses and grips the protective sheet 61. Further, since one side of the chuck 52 has a comb shape, even if one side of the chuck 52 is closed, the comb portion of the guide portion 53 can be passed, and the protective sheet 61 can be held without coming into contact with the guide portion 53. .

In addition, by providing the sheet supply stage 81 and the discharge stage 83, it is possible to automate the loading of the component-embedded sheet 67 and the carry-out of the electronic component 60, and the workability is improved. In addition, in a subsequent step, for example, the electronic component 60 is packaged on a substrate of the smartphone. Therefore, in order to easily hold the electronic component 60 for the packaging device of the subsequent step, it is preferable to carry it in the subsequent step in a state where the top surface 603 on which the electromagnetic wave shielding film 605 is formed is upward. The packaging device is required to have a high degree of positioning accuracy, and thus the electronic component 60 on the discharge tray 831 is also required to have positional accuracy. Therefore, it is desirable that no positional deviation occurs from the position where the electronic component 60 is arranged on the component unmounted sheet 65 as much as possible.

Therefore, the discharge table 83 is provided with a tubular member 83b having stretchability and sealing property so as not to cause a positional shift when the electronic component 60 is transferred to the discharge tray 831. In addition, by making the surface of the discharge tray 831 adhesive, the positional shift at the time of the transfer of the electronic component 60 is suppressed, and the positional shift of the electronic component 60 at the time of conveyance in the subsequent step is suppressed.

In addition, as compared with the configuration in which the protective sheet 61 has been peeled off after the chuck 52 has been peeled off, the rotating arm 85 and the rotating mechanism 84 are provided separately from the chuck 52, so that the chuck 52 can be provided. The drive unit has a simple structure.

In the peeling processing unit 5, a detecting unit that detects the tensile force when the protective sheet 61 is peeled off by the chuck 52 is provided. When the tensile force becomes a predetermined value or more, it is determined that the electronic component 60 has not peeled off from the protective sheet 61. The operation of the peeling processing unit 5 is stopped. As a result, the yield can be improved.

(Other Embodiments) The present invention is not limited to the above-described embodiments, and includes the following aspects. That is, as shown in FIG. 28, the film forming apparatus 7 may further include a transfer unit 71 that is responsible for the component mounting step. The transfer unit 71 is responsible for the component placement step, and transfers the electronic component 60 from the tray on which the electronic component 60 before the film formation process is placed toward the component unmounted sheet 65. For example, the tray may be arranged adjacent to the component unmounted sheet 65, and the transfer unit 71 may be a robot that can move vertically and horizontally within a range including the tray and the component unmounted sheet 65. At the front end of the arm of the robot, for example, a vacuum chuck is provided. The transfer unit 71 generates a negative pressure on the tray to hold the electronic component 60, and releases the negative pressure on the component unmounted sheet 65 in a vacuum break or an atmosphere opening or the like, and arranges the electronic component 60 on the component unmounted sheet 65. on.

In addition, although the film forming apparatus 7 is a device including the embedded processing unit 1, the board mounting unit 2, the film forming processing unit 3, the board releasing unit 4, and the peeling processing unit 5, the respective units may be independent. The device is constructed and systemized. In other words, the embedding treatment unit 1 may be an independent embedding treatment device, the plate attachment portion 2 may be an independent plate attachment device, and the film formation treatment unit 3 may be an independent film formation treatment device, and the plate release portion 4 may also be used. It may be an independent plate releasing device, and the peeling processing unit 5 may be an independent component peeling device.

Further, in the above-described embodiment, the height H1 from the surface of the component array region 615 to the upper end surface of the frame 62 is set to be higher than the height H2 from the surface of the component array region 615 to the top surface of the electronic component 60. However, it is not limited to this, and may be lower than the height H2. In this case, the area of the flat surface 112, the flat surface 212, and the flat surface 412 of the top portion 11, the top portion 21, the top portion 41 facing the part arrangement region 615 is formed to be recessed only by the difference between the allowable height H1 and the height H2. The concave portion of the amount may be formed to form the sealed space 14, the sealed space 24a, and the sealed space 45.

In the peeling treatment unit 5, when the electronic component 60 is peeled off from the protective sheet 61 in which the component 67 has been embedded, the frame 62 is also peeled off from the protective sheet 61, but the invention is not limited thereto. Here, the electronic component 60 and the frame 62 may be peeled off from the protective sheet 61 by separate steps. In short, the peeling treatment portion 5 and the component peeling device may have a function of peeling at least the electronic component 60 from the protective sheet 61.

In addition, although the frame 62 in which the component has been embedded in the sheet 67 is supported by the mounting table 51, the present invention is not limited thereto, and the frame 62 may be held on the mounting table 51 by a holding member such as a vacuum chuck. Further, in order to detach the frame 62 from the mounting table 51, a member for supplying a positive pressure or a separating member such as a peeling pin may be provided.
