Rnc. I VVH ih2F IX. Description of the Invention: [Technical Field] The present invention relates to a flux tool for a ball ball machine for manufacturing a semiconductor component and a flux probe thereof, and more particularly to A quantity and amount of flux is placed on a substrate or a flux tool and a flux needle on a dense pattern of wafers. (The term "substrate" as used herein refers to a wafer-related component.) [Prior Art] A Soder ball attaching machine (SAM) is a solder attaching tool that applies fine soldering. A ball placed on a plurality of patterns formed in a wafer or substrate. (Substrate referred to in this specification and the scope of the patent application refers to a semiconductor-related component, including a wafer or a substrate, etc.) _ In general, a ball plant includes a feeding unit and a helping agent. a flux attaching unit, a solder ball attaching unit, and an inspection unit. The feeding unit is configured to transport the substrate 2〇 one by one to enable the solder ball to be placed on the substrate The flux attachment unit is used to place the auxiliary agent on the substrate conveyed by the feeding unit. The solder ball attaching single tube is used to place the solder ball on the pattern of the substrate. Verify that the solder balls are successfully attached to the pattern of the substrate. The feeding unit is from the storage chamber storing 10 or 20 substrates one by one 200840676

Me: i vv^f i^F Draw the substrate and fix the substrate on the machine. The machine is then transferred to the flux attachment unit and the solder ball attachment unit. As shown in Fig. 1, the substrate includes a plurality of patterns, and the pattern forms a plurality of pattern units 22 (e.g., a group of patterns form a pattern group). Therefore, the substrate is divided in accordance with the corresponding pattern group, so that a plurality of individual semiconductors are thus formed. In other embodiments, for example, as shown in Fig. 1, a plurality of pattern groups may also form a plurality of pattern blocks 23 (e.g., a group of patterns _ groups form one pattern group 23). By firmly fixing the flux tool 10, as shown in Figures 2 and 3, and precisely controlling the position of the flux tool 10, and operating the soldering back j attachment unit to separate a small amount of flux separately On the pattern 21 of the substrate 2〇. The conventional flux tool 1 includes an upper case 11, a lower case 12, a plurality of flux pins 13, an elastic layer 14, and a buffer layer ( Buffering • layer) 15 and a number of fastening bolts (not shown). The upper casing 11 has a plurality of through holes. The lower casing 12 has a plurality of stepped holes corresponding to the patterns 21 in the substrate 20. The assisted seven] needle 13 series δ is placed in the stepped hole 12a. The elastic layer μ is for pressing the flux needle 13 so that the flux needle 13 protrudes from the lower casing 12. The buffer layer 15 is located between the upper casing and the elastic layer μ, so that the elastic layer 14 firmly and uniformly presses the auxiliary needle 13 . A fixing bolt (not shown) is used for the upper casing 11 and the lower casing 12 to be joined by the through hole Ua and the screw hole m. Wherein, the head of the flux needle is placed in the stepped hole 6

200840676 r!ie. I vy兮丨呌2F 12a step surface. The flux pins 13 are arranged corresponding to the pattern 21 of the substrate 20. Therefore, the flux is extracted from the end of the flux needle 13 protruding from the lower casing 12, and the flux tool 10 located near the substrate 20 and the light pressure flux needle 13 are accurately moved on the substrate 20. Pattern 21 to complete the flux attachment process to the substrate. In order to operate the above-described flux tool 10, the flux tool 10 has two pin holes 17 which are separately provided on one side of the reference surface with precise tolerances. Therefore, the flux tool 10 can be precisely fixed in the flux attachment unit. In order to make the subsequent solder ball attaching process more reliable, it is necessary to precisely control the dose of the flux placed on the pattern 21 of the substrate 20. However, even if the position of the flux tool 10 is precisely controlled, as shown in Fig. 5, when the elastic layer 13 is slightly lifted or rotated by the flux needle 13, the flux pins 13 are not uniformly aligned vertically. The direction is moved such that the flux needle 13 first touches the substrate 20. Therefore, the flux needle 13 which first touches the substrate 20 will place more flux on the pattern 21. The flux needle 13 which is farther from the flux needle 13 which first touches the substrate 20 will place less flux on the pattern 21 because the distance first touches the flux needle 13 of the substrate 20. The farther flux needle 13 is not subjected to sufficient pressure by the elastic layer 15. In addition, although it is intended that all of the flux pins 13 are moved perpendicularly to the stepped holes 12a by a constant gap c as shown in Fig. 4, in reality, most of the flux pins 13 are vertically moved. Time will bring

Therefore m secret _ surface of the flux The dose may not be pre-existing on the pattern 21 of the soil material 20 to promote the production of X, out of the box ~ /, because the actual diameter of the flux needle, the protruding length X is still short. t Use a smaller diameter flux u _ right loss ^ C, and deformation, deformation after the help head Λ flux needle 13 will interfere with the soil! Set the help agent in the flux adhesion process

Less flux is on the pattern 21 of the substrate 20. "曰Place ▲ The mouth is placed on the pattern U of the substrate 2, and the amount of soldering is placed on the pattern U. The solder ball cannot be firmly attached to the pattern, thus causing the rear (four) solder ball adhesion. In the process, there is a delay in the semiconductor process caused by a bad condition. As shown in Fig. 6, the flux needle 13 includes a - head portion 13a, a body portion 13b, and a flux extracting portion 13c. The head Ua has the largest diameter to be placed on the step surface of the stepped hole 12a. The main body portion 13b extends from the head portion 13a and the diameter of the main body portion 13b is smaller than the diameter of the head portion i3a. The flux scooping portion 13c extends from the end surface of the main body portion 13b and is used to draw the flux. Here, when the head portion 13a is placed on the step surface of the stepped hole 12a, the main body portion 13b is provided in the stepped hole 12a. The conventional flux needle 13 is made of a beryllium bronze (berylHum bronze). Although conventional flux needles are completed by a cutting process that is easy to mold, it is necessary to perform electroplating or coating for corrosion resistance. In particular, the conventional soldering needle 13 is complicated to fabricate. As shown in Figure 7, the first, in step S1, the bronze bronze 8 200840676

Factory llti. I VVH 丨 h2F Base metal must be cut first by lathe and grinding machine. Next, in step S2, chrome plating treatment is performed on the surface of the flux needle 13. Then, in step S3, gold coating treatment is performed on the surface of the flux needle 13. This type of manufacturing creates costly costs. As shown in Figures 8 and 9. During the reflow process, the solder balls 40 placed on the pattern 21 of the substrate 20 are melted and form an arch-formed bump 40' on the corresponding pattern 21, respectively. In particular, as electronic devices become more compact, the integration of electronic components is higher. In order to cope with such a trend, the pattern 21 of the substrate 2 must be arranged more densely than in the first drawing. Therefore, the distance between the respective patterns and the diameter D1 thereof become smaller. Specifically, in the latest process, the diameter of the solder balls placed and attached to the pattern 21 of the substrate 20 is 〇.3 mm. However, it is expected that there will be a smaller solder ball size, such as a 0.1 mm diameter application. When the pattern 21 of the substrate is more densely arranged, the flux should be placed in a fixed range associated with the diameter D1 of the pattern of the substrate (for example, the figure is straight from the iiq% of D1). Assuming that the flux is placed beyond the center of the pattern, the attachment of the Tan ball will exceed this range. It is possible to occur with the adjacent distance between the current bumps. Therefore, in order to accurately place the flux on the pattern 21 of the substrate 2, the flux needle 31 needs to be made finer to draw a more precise flux dose. In order to achieve the above object, in a conventional practice, the flux needle 13 has a flat end surface 13cl, as shown in Fig. 10 or ', has a round end surf ace 12e2, as in the first 11 Figure 9 200840676

卜"e: f VV414ZF or an end face with a chamfer on the circumference of the flat face, as shown in Figure 12. However, the end of the conventional flux needle 13 as shown in Figs. 10 to 12 cannot extract sufficient flux. Further, as the diameter of the flux needle 13 becomes smaller, the flux to be taken becomes smaller. Thus, the flux attached to the pattern 21 does not effectively remove the oxide and does not help the solder ball to firmly adhere to the pattern 21. Further, as shown in Fig. 6, the chrome-plated surface of the conventional flux needle 13 does not have the plating layer 14 of uniform thickness. That is, the edge portion 14a of the plating layer is thicker than the other portions of the plating layer 14. Due to the uneven thickness of the plating layer, the conventional flux. The effect of the flux on the needle 13 is poor. Further, it is difficult to control the tolerance of the tapping portion i3c of the flux needle 13 when it is difficult to control the thickness of the plating layer. Furthermore, when the high visc〇us fat-soluble flux is limited in environmental protection, it is necessary to make 甩 viscous water-soluble flux (l〇w viscous water-soluble flux) However, the 'low viscosity water-based flux thermal method allows the flux needle 13 to draw a sufficient amount. Further, when the patterns 21 of the substrate 20 are arranged more closely with each other, the flux needle 13 must also be made smaller, so that it is more likely to fail if a sufficient amount of flux is taken. The finer rod-forming needle 13 is frequently used to change the flux needle 13 due to the user's negligence due to the user's negligence or due to frequent repeated use. This reduces process efficiency. - Therefore, when the flux needle is required to take enough amount of low viscosity water-based fluxing 200840676

Mie: For the W4 I42F agent, the flux needle needs to maintain a straight shape and high deformation rigidity. This can be used for a long period of time without replacement, even in the case where the diameter of the flux needle 13 becomes small in order to match the dense arrangement of the pattern 21 of the substrate 20. SUMMARY OF THE INVENTION In view of the above, the present invention provides a flux tool and a helper needle thereof. The flux tool is applied to a ball placement machine in a semiconductor component. The pressing elements of the aid needles press the flux pins on the pattern group of the substrate, respectively, so that a sufficient amount of quantitative flux is accurately transferred to the densely packed pattern in the substrate. In addition, another object of the present invention is to prevent the flux tip from being bent early in the process of placing the aid on the pattern of the button by applying a flux. In another aspect, it is an object of the present invention to reliably place a quantity and a sufficient amount of flux on a pattern of densely packed substrates in a substrate. Furthermore, the present invention provides a fluxing needle for filling each pattern on a substrate by drawing a sufficient amount of a fluxing agent, even if it is to match the pattern on the substrate, so that the flux The case where the needle has to be very small is no exception. On the other hand, the object of the present invention is to provide a guide block for use in a flux tool. The guiding environment guides the massaging element to press the flux phase of the pattern of the substrate, even in the case where the patterns on the substrate are densely arranged. , 200840676 Factory lie. ! V ν«+ ΐηζίΡ On the other hand, another object of the present invention is to manufacture a guide block which is low in cost and easy to manufacture. Still further, it is an object of the present invention to provide a flux needle. Flux needles have high bending stiffness and allow a sufficient amount of flux to fill the pattern of the substrate even when the flux needle becomes smaller to fit the pattern size. In another aspect, the object of the present invention is to provide a flux probe that allows a sufficient amount of flux to be obtained even with a low viscosity aqueous flux. In another aspect, it is an object of the present invention to provide a flux tool. The flux tool has a flux needle. Flux needles have a high enough bending stiffness to allow the flux needle to be used for long periods of time without having to change even when the flux needle is smaller than a conventional flux needle. On the other hand, it is an object of the present invention to provide a flux pin which does not cause corrosion even in the absence of surface treatment such as plating or coating. Furthermore, it is an object of the present invention to produce a low cost flux probe quickly and simply. In order to achieve the above object of the present invention and other aspects of the present invention, the present invention provides a flux tool for placing a flux on a pattern of a substrate, the substrate comprising a plurality of pattern groups, a pattern group It is formed by a plurality of patterns. The flux tool includes a plurality of flux pins, a plurality of dust-collecting elements, and a plurality of springs. Flux needles correspond 12 200840676

File: i VV414ZF is arranged in the pattern of the substrate. It is quite irritating &#长压兀 is arranged in accordance with the configuration, each press is a map-group, λ π仟 has a pressing surface (pressing surface), bearing ^ ^ ^ u The pressing surface is in contact with a flux needle corresponding to one or a group of patterns. The cage 4 is such that the 4b flux needle corresponding to one of the pattern groups to one of the 夕 夕 被 is pushed, and the end of the flux needle protrudes from the material

That is, in order to place a predetermined amount of flux on the pattern of the substrate, the 'welding' heads should be protruded and elastically supported by each other. By pressing the flux pins corresponding to the - or some of the groups, all of the flux pins can be supported by a constant elastic force to allow the flux pins to contact the pattern of the substrate. Thus, a quantitative flux can be placed on the pattern of the substrate. Since the pressure receiving surface of the pressing member is formed at the end of the pressing member, the pressing member can be uniformly pressed against the flux needles corresponding to one pattern group. Further, the opposite side of the pressure receiving surface of the pressing member forms a deep receiving groove which accommodates a portion of the spring. A simple and robust combination of the pressing element and the spring is formed. More specifically, the length of the flux needle to the spring is thus made shorter. Further, the fluxing tool further includes at least one outer plate and at least one guiding block. The outer panel has a plurality of through holes corresponding to the pattern. One portion of each flux pin protrudes from the corresponding through hole. The guiding block has a plurality of guiding holes for respectively guiding the pressing element, the piece p, and the guiding block is coupled to the outer plate. From the outside 13 200840676

Hue: i W4 i^2F board to guide block form a module, making it easier to control. It is worth mentioning that the 疋 卜 board and the 丨 丨 block only include a group of patterns formed by a plurality of patterns (4), so the module can form a unit of a single pattern group. Further, the pressing member is formed by a piliar having at least one protruding portion ({〇拎〇拎〇拎11), by the projection between the protruding portion and the guiding hole Interference so that the pressing member cannot pass through the guide hole. Therefore, it is easy to assemble these pressing members to the guide block. 10 Although it is feasible that each of the pressing members is pressed against those flux pins corresponding to some of the pattern groups, it is preferable to construct each of the pressing members to correspond to those of the flux groups in one pattern group. In the illustration, the pattern group is the smallest unit for pressing the flux needle, so that each of the pressing elements is pressed against the flux needles corresponding to one of the pattern groups, so that the flux needles can move uniformly and Accent consistently and accurately. Further, the height h2 of the pressing member is longer than the length of the edge of the bearing surface, so that each pressing member passes through the guiding hole in a precise straight path. That is, if a flux needle is in contact with the pattern of the substrate before the other flux pins, the pressing member first contacts the inner surface of the guide hole before the flux needle contacts the through hole of the outer plate. Thus, the possibility that the flux needle is bent and deformed by contact with the inner edge of the through hole of the outer panel can be substantially eliminated. Furthermore, the flux tool further includes a spring support plate for the spring. The magazine floor is attached to the guide block. Similarly, it can be assembled to operate the flux tool 200840676

Bu ue: The complete module of the IVV4142F. That is, the present invention also provides a flux tool. The flux tool is used to place the flux on the pattern of the substrate, the substrate comprising a plurality of pattern groups, and the pattern group is formed by a plurality of patterns. The flux tool includes a plurality of flux pins, a plurality of pressing elements, a plurality of bombs, at least one outer panel, and at least one guiding block. The flux pins are arranged corresponding to the pattern of the substrate. The pressing members are arranged corresponding to the arrangement of the pattern groups of the substrate, and one end of each of the pressing members has a pressure receiving surface which is in contact with the assisting agent needles corresponding to each of the pattern groups. A spring is used to press each of the pressing members to push the flux pins in each of the pattern groups such that the ends of the flux pins protrude from the outside. The outer plate has a plurality of through holes, the through holes corresponding to the pattern, and a portion of each of the flux pins projecting correspondingly through the through holes. The guiding block has a plurality of guiding holes for guiding the corresponding pressing members. The guiding block and the outer board are combined with each other, and the guiding block further comprises a pattern group, and the pattern group is formed by a plurality of pattern groups. More progressively, the present invention provides a guide block for a flux tool. The guide block of the aid agent tool is used to place the flux on the pattern of the substrate. The substrate includes a plurality of pattern groups, and the pattern group is plural. Formed by a pattern. The guide block of the flux tool includes a plurality of first sheets and a plurality of second sheets. The first sheets are arranged side by side in parallel, and the second sheets are arranged side by side in parallel. The first thin plate and the second thin plate are arranged to cross each other, and the first thin plate and the second thin plate are surrounded by a plurality of guiding holes at the intersection. When the pressing member is outwardly pressed, pressing in at least one of the pattern groups 15 200840676

Rue: i W4142F For those flux probes, the flux needle is guided through the guide hole. That is, when the first thin plate and the second thin plate are arranged to intersect each other, a plurality of spaces are formed between the first thin plate and the second thin plate for guiding the linear movement of the pressing member. The guiding block can easily form a plurality of guiding holes corresponding to the minimum pattern group. Preferably, it has recently been demanded that the pattern group of the substrate be arranged finer and denser on the substrate, and such a guide hole is difficult to manufacture using a cutting process. Therefore, when the guide holes are formed in a crosswise manner by a plurality of thin plates, it is possible to eliminate the use of the cutting process and to quickly produce a low-cost guide block. In order to form a plurality of spaces, for example, by guiding holes formed by intersecting the first thin plate and the second thin plate, an accommodating slot can be along at least one of the first thin plates and at least the second thin plates One of the planar directions is formed, and the receiving slit is for receiving the first thin plate and the second thin plate. If the accommodating slit is formed only in one of the first thin plate and the second thin plate 0, the depth w of the accommodating slit is preferably deep enough. Further, by the bonding process, for example, spot welding at at least one intersection between the first thin plate and the second thin plate, the assembled state of the first thin plate and the second thin plate can have a fixed effect. However, even if the bonding process is not used, the first thin plate and the second thin plate can be assembled by inserting. The assembly state of the lattice structure can be maintained by the restraint of adjacent components. Therefore, the integration process is not necessary. Further, the first thin plates are arranged in parallel and juxtaposed to each other, and the second thin plate systems are also arranged in parallel with each other in parallel. In other words, the pressure bearing surface is better 16 200840676

File: TW4142F is formed corresponding to the pattern group. If the pattern group forms a series of diamond-shaped shapes, the first thin plate and the second thin plate are arranged parallel to each other and juxtaposed, and the angle between the first thin plate and the second thin plate is also formed corresponding to the diamond shape. . ^ < In addition, if the pattern group forms a series of rectangular shapes or a series of square shapes, the first thin plate and the second thin plate are arranged in parallel and juxtaposed, and the first thin plate and the second thin plate cross each other perpendicularly. (For example, the angle between the first thin _ plate and the first thin plate is a right angle). In this way, the flux elements are effectively pressed against those flux pins corresponding to the pattern type. In order to assemble the flux tool into at least one module to facilitate operation, it is preferable to include a block body. The body has a hollow penetrating part, and the penetrating portion is located at a central portion of the body to receive the first sheet and the second sheet. The sidewall of the through portion is formed with a plurality of slots, and the slot is for receiving the end of the first thin plate and the end of the second thin plate. A bonding method, such as _4 bonding or bonding, can be applied to the socket such that the first sheet and the second sheet are firmly bonded to the body. Applying the above-described guide block, the present invention also provides a flux tool for placing the assisting agent on a pattern of one of the substrates. The substrate comprises a plurality of pattern groups, and the pattern group is composed of a plurality of patterns. The flux tool includes a plurality of fluxing pins, a plurality of pressing elements, a plurality of springs, and at least one guiding block. The flux pins are arranged corresponding to the pattern of the substrate. The pressing members are arranged corresponding to the pattern of the pattern of the substrate, each of the pressing members has a pressure receiving surface, and the bearing surface is in contact with the least pattern group.

The spring presses each of the pressing members to push the flux pins corresponding to at least one of the pattern groups such that the ends of the flux pins protrude from the outside. The guiding block comprises a plurality of first sheets, a plurality of second sheets and a body. The first sheet is arranged side by side in parallel with each other. The second sheets are arranged side by side in parallel. The system has a penetrating portion which runs through the central portion of the body, and the penetrating portion is for receiving the first thin plate and the first plate. A plurality of slots are formed in the side walls of the through portion for receiving the ends of the second jaw and the ends of the second sheet. Wherein, the first thin plate and the second thin plate are arranged to cross each other, and the intersection of the first plate and the second thin plate surrounds the guiding hole of the female, and the pressing force is pressed outwardly to the flux needles in the corresponding group, so that The flux needle is guided through the guide hole. b is manufactured at a price by applying a guide hole for a fine guide hole formed by a plurality of first thin plates and a plurality of second thin plates.

Fi!e: TW4142F =, the 'outer plate has a plurality of through holes, and the through holes correspond to the figure f > one part of the flux needle protrudes or is exposed to the outside. In other words, the diameter of the head of the n 'flux needle is larger than the diameter of the through hole of the outer plate. Therefore, the head of the auxiliary needle is located in the flux worker ^ and bribes through the outer plate. Guide hole. Wherein, the outer plate is bonded to the body port. Unless the outer plate is separated from the body, the position of the flux needle is maintained in the through hole of the outer plate. Further, each of the pressing members is pressed against those flux pins corresponding to one pattern group. In other words, in order to place a certain amount of flux on the substrate of the substrate, all the flux needles are subjected to the flux when the flux is taken from the end of the flux needle to the substrate. Consistent elastic force 'so it will stand out consistently. Therefore, by pressing one of the flux pins corresponding to one of the pattern groups on the f-material (for example, the smallest unit group in the substrate), those flux needles will be in substantially the same time. The elastic contact force acts on the pattern. Thus, the flux drawn by the end of the fluxing needle is placed on the pattern of the substrate at a predetermined dose. Each spring exerts an elastic force on the pressing member to cause the pressing member to be pressed outwardly against those flux pins corresponding to a pattern group or groups of patterns. Thus, the conventional problem that the protruding length and the protruding elastic force are different from the position of the flux needle can be solved. In addition, in order to maintain a uniform compression length for each of the springs, the assisting agent needle further includes a bf support plate, and the elastic yellow support plate has a predetermined stroke from the body. The magazine supports the opposite side of the position where the flux needle is located on the body of the panel. So, 19 200840676

rilG. 1 VVH IHr2F is capable of assembling a module that includes a spring. The present invention provides a flux needle. The flux needle has at least one extension having a cross-section that is smaller than the area of the end face Μ# of the flux needle, the extension being used to draw the flux. That is to say, when the cross section of the at least one protruding portion is smaller than the area of the end surface of the flux butt, the flux needle can draw more flux by the space between the protruding portion and the end surface. And because of the relationship between the surface tension, the flux is formed into a spherical or hemispherical shape on the flux needle: specifically due to the presence of the flux lion's extension, the (4) flux is covered in a spherical or hemispherical shape. On the out. Wherein, the protruding portion is fixed or changed by a cross section, for example, a cylinder or a cone. If the loose wearing surface is small, the distance of the protruding portion from the end surface is also relatively long. In addition, the protruding portion may be composed of a columnar body having more than one step surface 232db. That is, the protruding portion can be of any shape as long as the flux can be filled up. The space between the end face 232y of the flux needle and the protrusion is 232x. /, Name - In addition, the flux needle is made of an anti-corrosion material, so the surface of the flux head does not need to be plated. Therefore, the flux needle can be It is simple and inexpensive to manufacture by a mechanical cutting process (eg turning or milling). In addition, 'traditional flux needles will get less flux under the influence of uneven thickness plating. Unlike conventional flux needles, the flux needle of the present invention can draw more flux because there is no plating layer: Specifically, the flux needle is preferably made of stainless steel, stainless steel 20 200840676

"E: The bending rigidity of iW4l42F is better. Thus, in the case where the flux needle has to be made fine to match the fine pattern on the substrate, the auxiliary needle made of non-rotating steel has a high The deformation is rigid, so the flux pin can still be used reliably and repeatedly for a long time without replacement. Compared with the flux needle made of bronze, the flux needle made of non-recorded steel has a rough after the cutting process. Surface roughness. That is to say, the flux needle made of stainless steel provides a relatively large contact area for the flux, so that the flux needle is firmly entangled by the aggregation effect in the principle of surface tension. In addition, the flux needle includes a head part, a body part, and a flux pickup part. The head is located inside the flux tool. The cross section of the body portion is smaller than the cross section of the head portion, and the body portion extends from the head and is selectively and partially exposed through the through hole of the flux tool to the flux worker The flux extraction portion has a cross section smaller than a cross section of the main body portion, and the flux extraction portion extends from the main body portion and has at least one protruding portion, and the protruding portion is located at an end portion in the long axis direction Since the diameter of the head is larger than the diameter of the through hole, the head cannot pass through the through hole, and the head is placed inside the flux tool. The diameter of the main body portion and the diameter of the flux extraction portion are larger than those of the through hole. Straight I is also small, so the main body and the flux extraction portion are exposed to the outside, and the center line of the head, the center of the main body, and the center of the flux extraction portion are located on a common line, thus facilitating The flux is easily placed on the pattern of the substrate.

200840676 hue: IW4142F In addition, if the cross section of the flux needle is round, it is feasible to carry out the process by setting the material of the needle to the head of the lathe. The length of the extension (4) is smaller than the diameter of the auxiliary (4) needle = D3 and larger than 1/6 of the end face diameter D3. In other words, if the length h of the extension is larger than the diameter D3 of the end face, the flux that is drawn on the end face of the flux pin can not be surrounded by a spherical or hemispherical shape. Around the extension, the flux needle cannot pick up enough = flux. In contrast, if the length h of the extension is smaller than the diameter of the end face, it is difficult to form the protrusion by the machining process. The diameter of the bottom of the extension is 4 The diameter of the 卯 /5. When the diameter of the bottom is more than 4/5 s of the diameter D3 of the end face, the space 232x between the extension and the end face 232y may not be large enough. Thus: the effect of filling 232x is not so good. In contrast, when :' causes a weld to fill the gap between the extension and the end surface, the amount of flux that is picked up is lowered.

The flux pin block 130 is housed in the accommodating space ηι and is elastically supported by the flux pins 132 arranged corresponding to the pattern 21 of the substrate 20. Wherein, when those soldering 4 needles 132 corresponding to the smallest unit of one pattern group 22 are supported or pressed by the pressing member 133, if any of the fluxing needles 132 are in contact with the pattern other than the other fluxing needles 132, it is not indicated. All of the astringent needles are in substantial contact with the substrate 21 at the same time. Therefore, a predetermined dose of the flux can be reliably carried from the end of the soldering two needles 132 to the pattern 21. In addition, the flux needle can be prevented from deforming during the transfer of the flux.

^The shell 110 1 has two positioning holes 112, which are precisely divided into strict tolerances to enable the ball planting machine to more precisely control the fluxing tool's additional 'fixing groove (flxing §rGQve) llla system It is formed on the sidewall of the capacitor 'i-ii to fix the position of the flux needle block 131.

The pressing member 133 is for pressing against a corresponding one of the pattern groups 22' of the pressure receiving surface 133b to form a quadrangle corresponding to the pattern group 22. The side wall of the cylinder extends a projection portion 133c, and the projection portion 133c interferes with the guide hole 135a as shown in Fig. 16 so that the range of movement of the pressing member can be restricted. The deep groove 133a is for receiving a portion of the coil spring 134. In the present embodiment, although a flux element corresponding to one pattern group 21 is pressed by a case pressure member, the pressing member can be made to be pressed as long as the movement of the flux needle is linearly moved.

Avoid the auxiliary lancet 132 and the through hole 131& the sound is kept straight to maintain the protrusion of the flux needle 132. Length: thickness m:: the length h2 of the piece 133 should be larger than the hole of the guiding block 135; the T inch is such that the flux needle 132 contacts the penetrating 135: the female pressing element 133 will first contact the guiding block, The flux pin and the through hole 13 of the outer plate 131 = interference can basically be avoided, the spoon is avoided. Thus, the deformation of the assisting dry needle 132 is guided: the two supporting plates 137 are fixed to the surface by =1 3 by bolts (SCreW) 136c. Wherein, the two sides of the spring support floor 137 are angulated by four. Therefore, the 'bending length in addition to the moving distance of the pressing member' also determines the compression length of the job spring 134.

Hue: I VV4T42F Although the above embodiment has the case where the first thin plate 221 and the second thin plate 222 are formed with the accommodation slits 221a and 222a as an example. However, if the lattice structure 220 can accommodate the inconsistent top and bottom surfaces, the receiving slits may be formed only in one of the first thin plate 221 and the second thin plate 222. When the accommodating slit is formed only in one of the first thin plate 221 and the second thin plate 222, the depth of the slats 221a, 222a is preferably as deep as possible.

As shown in Fig. 25, the flux needle is applied to the flux tools 1〇〇, 1〇〇 of the first embodiment and the second embodiment. The flux needle includes a head portion 232a, a body portion 232b, and a flux extraction portion 232c. The diameter of the head portion 232a is such that the head portion 232a cannot pass through the through hole 131a of the outer panel 131. The diameter of the main body portion 232b is such that the main body portion 232b cannot pass through the through hole 131a of the outer panel 131. The diameter of the flux scooping portion 232c corresponds to the pattern size of the substrate 20 and the flux scooping portion 232c has an extending portion 232d extending from the end surface 232y. Further, the head portion 232a is located within the flux needle block 13A, 200 to receive the elastic force of the pressing member 133 so that the flux capturing portion 232c is large outside. In this regard, although the head 232a is desirably as large as possible, the diameter of the head 232a is limited because the flux needle 232 must be drained corresponding to the pattern 21 of the substrate 20. —P 232b needs to have high deformation rigidity to avoid deformation of the flux needle. Due to the skin, the body portion 232b is determined by the alignment error of the flux needle 232, and the straight line of the main body is determined by the rain which does not interfere with the through hole i3la of the outer plate 131. - Flux #1 The diameter of the portion 232c is such that the flux can be placed on the 34 200840676 native pattern 21 within a range of 110% of the diameter D2 of the pattern 21. 1 That is, as shown in Fig. 26, the projecting portion 232d protrudes into a round body, and the projecting portion 232d is located on the flux extracting portion 232c on the end surface 232y of the long axis direction of the flux needle 232. . The straight ridge D4 of the protruding portion 232d is about 1/3 of the diameter D3 of the flux absorbing portion 232d.

The length h of the exit pupil 232d is also approximately 1 / q 〇 lU i of the diameter D3 of the flux extraction portion 232d. That is, although the 26th drawing exaggerates the shape of the protruding portion 232d so that the shape of the protruding portion 232d is easily understood, the diameter and length of the protruding portion 232d are actually larger than that of the 26th drawing. Still have to come small. Further, as shown in Fig. 26, by the surface tension of the flux 88, the flux 88 fills the space 232 位于 between the end face 232y and the side 232da of the overhanging portion 232d, as shown in Fig. 27. It is shown that the protrusion 23 is capable of drawing more flux. _ $Helper needle 232 is made of stainless steel. Although traditionally bronze =: flux needles can be used to make electric clocks or coatings to avoid surface rotting ability, it is complicated to manufacture and because of the inconsistent thickness of the plating layer, the 撷 刚 has just fallen. The flux needle 232 of the present invention is made of stainless steel having high fineness and steepness. Even if the thickness of the flux needle 232 is very good, the flux needle 232 can be reliably and repeatedly long-term kiss without deformation. . Who is more ^^ to help Minnan ~ step by step, because the non-recorded steel material itself has anti-soul, no need to further 4 needle 232 can be easily fabricated by mechanical processing and electroplating process or coating process. Therefore, compared to the cause of unevenness 35

2008406762F The electroplated layer causes the needle 232 with a low picking capacity to be able to take the flux 88 of the solder flux. A flux needle made of stainless steel, which is made of stainless steel, can be formed to have a roughness as shown in Fig. 26, and due to its high mechanical strength, i is unloaded. Specifically, 'traditional, mechanical cut

The surface is smoother. However, the extraction of flux probes made by b-clothes is not helpful. The smooth surface on the needle of the agent is soldered to a sufficient amount of flux. However, the conventional flux needle can not be taken. However, the flux needle of the present invention is made of stainless steel material, so I have a jittery jeJ O ^. Because of the high-strength glJ O ^ , the flux can still be extracted. __, even draw low (four) water-based flux. That is, the flux needle of the present invention has at least one projecting portion 232d which is located at the end face 23 of the flux needle and which has a rough surface roughness. The flux is filled in a spherical or hemispherical shape to fill the space between the end surface 232y and the protruding portion 232d, so that the flux needle can take the maximum amount of flux on the dog's couch. Flux needles can pick up the right amount of flux, whether the flux is a high viscosity oily flux or a low viscosity waterborne flux. The second side view of the flux picking portion of the flux needle of the flux tool as shown in Fig. 17 is shown in Fig. 8 and Fig. Further, the projecting portion 232d is formed in a cylindrical shape on the end face 232y of the flux needle, as shown in Fig. 28, the projecting portion 232d can be used.

2008406762F The shape of the columnar body is formed. The smaller the cross section of the columnar body is from the end face, the smaller. Further, as shown in Fig. 29, a projecting portion 232d" can be formed by a stepped column shape having more than one step surface 2 3 2 db on the stepped column body. The flux fill is performed by the surface tension principle to fill the space 232x between the end face 232y of the flux needle and the extension, in which case the extension can be of any shape. The fluxing needle having the above-mentioned protruding portions 232d, 232d', 232d" can take a larger amount of flux to fill the side wall 232da of the end surface 232y and the protruding portions 232d, 232d', 232d", The space between 232da, 232da". According to the present invention, if the pattern 21 of the substrate 20 is finer and denser to each other, the flux needle will be more finely fitted. Since the flux needle of the present invention has high deformation rigidity, it is possible to easily and quickly manufacture a flux needle having the ability to draw the maximum amount of flux. The aiding tool of the ball balling machine and the fluxing needle thereof disclosed in the above embodiments of the present invention have a plurality of advantages, and only some of the advantages are described below.

The pressing elements are arranged corresponding to the arrangement of the pattern groups of the substrate, 37 200840676 has one end

One end of the pressing member is formed as a columnar body. Pressing the pressing surface of the component, the bearing surface is in contact with a needle corresponding to a flux. The spring is used to press t仗! In the case of at least one (four) group, the (four) flux needle is pushed to make the flux:

The end of the needle protrudes from the outside to the pattern of the substrate. In the case of the arrangement, even in the case of contact with the pattern, the consistent length of the straw field, the force, still allows a sufficient amount of flux to be placed on the base of the figure. In addition, the invention can basically avoid The flux needle is bent and deformed in operation, because the pressing member first touches the inner surface of the guiding hole before the flux needle contacts the through hole 2 of the outer panel. ^: The flux needle can be reliably and repeatedly long-term use. Further, the present invention provides a soldering tool of a simple structure, the pressing member has a deep receiving groove, and the receiving groove accommodates the spring portion. Therefore, due to the existence of the receiving groove, the spring is assisted. The solder needle tip length will become shorter. The invention also provides a guide block and a flux tool. A flux tool is used to place a flux on a pattern of a substrate comprising a plurality of pattern groups. The pattern group is formed by a plurality of patterns.
