* * File: TW4142F IX. Description of the Invention: «Technical Field of the Invention The present invention relates to a flux tool and a flux probe for a ball ball machine for manufacturing a semiconductor element, and particularly relates to a use A flux tool and a flux needle for placing a quantitative and appropriate amount of flux on a substrate or a dense pattern on a wafer. ("Substrate" as used herein refers to a wafer-related component). [Previous Technology] A Solder Ball Attaching Machine (SAM) is a solder attachment tool that will be subtle. A solder ball is placed on a device formed on a plurality of patterns in a wafer or substrate. (The term "substrate" as used in this specification and claims refers to semiconductor-related components, including wafers or substrates, etc.) φ Generally, the ball plant includes a feeding unit and a flux. Flux attaching unit ' — a solder ball attaching unit and an inspection unit. The feeding unit is configured to convey the substrate 2〇, one by one, so that the solder ball can be placed on the pattern of the substrate. The flux attachment unit is used to place the flux on the substrate to be transported by the feed unit. The solder ball attachment unit is used to place the solder balls on the pattern of the substrate. The inspection unit is used to verify that the solder balls are successfully attached to the pattern of the substrate. The feeding unit is located one by one from the storage chamber storing 10 or 20 substrates.

File: TW4142F , pick up the substrate and secure the substrate to the machine. The machine is then transported to the flux v 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., the group pattern forms 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, such 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 of lugs form a 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 1〇, and operating the fluxing attachment unit to separate a small amount of flux separately On the pattern 21 of the substrate 2〇. The conventional fluxing tool 1 includes an upper casing (upper aSe>ll, a lower case 12, a plurality of flux needles]q, an elastic layer 14, and a buffer layer. (buffering ru) 15 and a plurality of fastening bolts (not shown). The machine 11 has a plurality of through holes. The lower casing 12 has a plurality of stepped holes corresponding to the pattern 21 in the substrate 20. A stepped hole 12a is provided in the stepped hole 12a. The elastic layer 14 is for pressing the flux needle 13' so that the flux needle 13 protrudes from the lower casing 12. The cushioning layer 15 is located Between the upper casing 11 and the elastic layer 14, the elastic layer 14 is embossed and uniformly pressed against the flux needle 13. A fixing bolt (not shown) is used to connect the upper casing 11 and the lower casing. 12 by the through hole 11a and the screw hole 12b β junction t A 4- θ 1 together, wherein the head of the flux tamper is placed in the stepped hole 6 1334365

* File: TW4142F 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 process of flux attachment to the substrate. In order to operate the above-described flux tool 10, the aiding tool 10 has two pin holes 17 which are separately disposed on one side of the reference ® face 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 probe 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 substrate 20 The flux needle 13 which is farther away from the solder 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. Will bring 7 1334365 4 t

File: TW4142F ^ t is rotated (four) degrees α ′ α, (d) is displaced by the rotational displacement of the elastic layer 13 and ‘−’ thus the contact of the inner surface of the flux needle 13 and the stepped hole 12a may occur. Therefore, the dose of the helper placed on the pattern 21 of the substrate 20 is unlikely to be a dose. Since the actual protruding length X' of the flux needle is shorter than the predetermined protruding length χ. In addition, if a smaller diameter flux probe 13 is considered, the flux needle 13 will be deformed by 1; the deformed flux will place less sensitizer on the substrate during the flux attachment process. On the pattern 21. Therefore, in the case where a quantitative flux cannot be placed on the pattern 21 of the substrate 2, the solder ball cannot be firmly adhered to the pattern 21, thereby causing a defect in the subsequent adhesion of the ball. Process delay. As shown in Fig. 6, the flux needle 13 includes a head portion 13 & a body portion 13b and a flux handling portion 13c. The head cymbal... has a maximum straight line 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. The flux scooping portion 13c extends from the end surface of the main body portion 13b and serves to extract the flux. Wherein, when the head portion 13a is placed on the step surface of the stepped hole 12a, the main body portion 13b is disposed in the stepped hole i2a. • The traditional flux needle 13 is made of a beryllium bronze (berylUum • bronze). Although the conventional flux needle 13 is completed by a cutting process having an easy-to-form advantage, it is necessary to perform an electric money or coating for the purpose of preventing recording. In particular, the conventional soldering needle 13 is complicated to fabricate. As shown in Figure 7, first, in step S1, 铍青青气 8 1334365 « «

File:TW4142F The base metal must be cut first by lathe and grinding machine. Next, the surface of the flux needle 13 is subjected to chrome plating in step S2. Then, in step S3, the coating treatment of gold 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 dazzled and form an arch-formed bump 40' on the corresponding pattern 21, respectively. In particular, Lu said that when electronic devices became smaller, the integration of electronic components would be higher. In order to cope with such a trend, the pattern 21 of the substrate 20 has to 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 ball placed and attached to the pattern 21 of the substrate 2 is 〇 3mnl. However, it is expected that there will be smaller solder ball sizes, such as the diameter 〇.lmm, the application appears. When the pattern 21 of the substrate is more densely arranged, the flux should be placed within a fixed range associated with the diameter D1 of the pattern of the substrate (e.g., 11% of the pattern D1). It is assumed that the placement of the flux beyond the center of the pattern & the circumference of the solder ball will also 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 20, the flux needle 31 needs to be made thinner to draw a more precise flux dose. In order to achieve the above object, in a conventional practice, the flux needle 13 has a fiat end surface i3ci, such as a first figure or a round end surface 12c2. 9 1334365

# File:TW4142F Or an end face with a chamfer on the circumference of the flat end face, as shown in Figure 12. However, as shown in Figures 1 to 12, the end of the conventional astringent needle * 13 cannot draw enough 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 mineral surface of the conventional flux needle 13 does not have a uniform thickness of the electrically forged layer 14. That is, the edge portion 14a of the plating layer is thicker than the other portions of the electric ore layer 14. Due to the uneven thickness of the plating layer, the effect of the conventional flux needle 13 on the flux is poor. More specifically, it is also difficult to control the tolerance of the tapping portion 13c of the flux needle 13 when it is difficult to control the thickness of the plating layer. Furthermore, when high viscous fat-soluble flux is limited in environmental protection, low viscous water-soluble flux must be used, but low viscosity The aqueous flux does not allow the flux needle 13 to draw a sufficient amount. In addition, when the pattern 21 of the substrate 20 is more closely arranged 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 the auxiliary agent is taken. The finer flux needle 13 is liable to be bent or deformed by the user's negligence in use or frequently replaced with the flux needle 13 due to frequent repeated use. This reduces process efficiency. Therefore, when the flux needle is required to protect the amount of low-viscosity water-based flux 1334365 4 «

File: TW4142F, the flux needle needs to maintain a straight shape and have 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 is 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 is directed to a flux tool and a flux probe therefor. The flux tool is applied to a ball placement machine in a semiconductor component. The pressing elements of the ® solder 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 another aspect, another object of the present invention is to prevent the flux needle from prematurely bending during application of the flux to the pattern of the substrate by applying a flux tool. In another aspect, it is an object of the present invention to reliably place a quantity and amount of A flux on a pattern that is densely packed in a substrate. Further, the present invention provides a fluxing needle which is filled with a sufficient amount of flux to fill each pattern on the substrate, even in order to match the pattern on the substrate, so that the flux The case where the needle has to be very small _ is no exception. In another aspect, it is an object of the present invention to provide a guide block for use with a flux tool. The guiding block guides the pressing member to press the flux needle in the pattern of the substrate, even in the case where the patterns on the substrate are densely arranged.丄 礞 ♦

Arranged in the pattern of the substrate. The pressing member outer material & $ m is arranged corresponding to the configuration of the pattern group of the substrate, one of each pressing member, . . . has a pressing surface (pressing surface), which corresponds to A flux on a needle in a group of political patterns. The spring system is used to press the pressing member so that at least one of the heads corresponding to the pattern group is pushed, and the end of the flux needle protrudes from the flux needle, that is, in order to be quantitative The flux is placed on the pattern of 2. The solder needles should be protruded and elastically supported. Fine-pressing of the flux needles corresponding to - or some of the drawings - all of the flux needles can be supported by a constant elastic force to allow the flux needle to contact the pattern of the substrate. Thus, θ ^ X of this 疋 1 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 the pattern groups. 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. In addition, the flux tool further includes at least one outer panel (exteri〇r = ate) and at least one guiding block. The outer plate has a plurality of through holes. The through holes correspond 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 member ◊, and the guiding block is coupled to the outer panel. From the outside 13 1334365 # *

File:TW4142F • The board-to-lead block forms a module that makes handling easier. It is worth mentioning that the outer panel and the guiding block only include a group of % patterns formed by a plurality of pattern groups, so the module can form a unit of a single pattern group. Furthermore, the pressing element is formed by a columnar body (the columnar body has at least one project ion, by the interference between the protruding portion and the guiding hole, so as to press The component cannot pass through the guide hole. Therefore, it is easy to assemble these pressing members to the guide block. Although it is possible for each of the pressing members to be pressed against those flux pins corresponding to some of the pattern groups, the preferred construction is such that each of the pressing members presses the flux pins corresponding to one of the pattern groups. In the illustration, the pattern group is the smallest unit for pressing the flux needle, so that each flux element is pressed against the flux needles corresponding to one pattern group, so that the flux needle can move uniformly and Accent consistently and accurately. Further, the southness h2 of the pressing member is longer than the edge length of the bearing surface by φ, 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 prior to the other flux pins, the uranium' pressing element that contacts the through hole of the outer plate with the flux needle will first contact the inner surface of the guide hole. Thus, the ability of the fluxing needle to be flexed and deformed by contact with the inner edge of the perforation of the outer panel is substantially ruled out. More specifically, the flux tool further includes a spring support plate for entrapping the spring. The spring support plate is coupled to the guide block. Similarly, it can be assembled to operate the flux tool 丄: U:) I >

The substrate comprises a plurality of soldering needles: a solid pattern. The flux tool comprises a plurality of outer plates and at least a "^^ pressing element, a plurality of springs, at least one Γ-: arranged according to a configuration of a pattern group corresponding to the substrate, and a pressure receiving surface at each end; The pressure surface is in contact with each of the ":tb flux needles. The spring is used to press the etch; P day ^-* pushes the flux needle in the mother pattern group, and the hole needle end is protruded outside The outer plate has a plurality of through holes. The hole system corresponds to the pattern. One part of each flux pin is attached to the through hole. The guiding block has a plurality of guiding holes, and the guiding = guiding bow corresponding The pressing member, wherein the guiding block and the outer panel are f (four) groups formed by a plurality of graph groups, and the pattern group is further described, the present invention provides a guiding tool for the flux tool The guiding block of the flux tool is used for placing the flux on the pattern of the substrate. The substrate comprises a plurality of pattern groups, and the pattern group is formed by a plurality of patterns. The guiding block of the flux J1 includes a plurality of first sheets. And a plurality of first sheets, the first sheets are arranged side by side The second thin plates are juxtaposed to each other, wherein the 'first thin plate and the second thin plate are arranged to intersect each other'. The first thin plate and the second thin plate are surrounded by a plurality of guiding holes at the intersection portion. When the pressing member is outwardly Pressing 15 15334365 corresponding to at least one pattern group

Fi!e: TW4142F 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 crisscross 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, 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 1334365

Fi!e: TW4142F. The ground 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 also corresponds to the diamond shape. form. Further, if the pattern group forms a series of rectangular shapes or a series of square patterns, 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 are perpendicularly intersected each other. (For example, the angle between the first thin plate and the thin plate is a right angle). Thus, the pressing members are effectively pressed against those flux needles corresponding to the type outside the pattern group. 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, and the penetrating portion is for receiving the first thin plate and the second thin plate. 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 _welding or bonding, can be applied to the socket such that the first sheet and the second sheet are firmly bonded to the body. Using the above described guide blocks, the present invention also provides a flux tool for placing the flux on the pattern of the substrate. The substrate comprises a plurality of patterns.

If this is the case, the fluxing tool preferably includes at least one outer plate as the machine. 18 1334365 ♦ t

File: TW4142F • For the purpose of the case, the outer plate has a plurality of through holes, and the through holes correspond to the pattern. One of the portions of each of the flux pins protrudes or is exposed to the outside. 'In other words, the diameter of the head of the flux needle is larger than the diameter of the through hole of the outer plate. Therefore, the head of the flux needle is located inside the flux tool and cannot pass through the outer plate. Lead hole. Wherein the outer plate is bonded to the body. Therefore, 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. In addition, each of the pressing members is pressed against those flux pins corresponding to a pattern group. In other words, in order to place a quantity of flux on the pattern of the substrate, all of the flux needles are subject to uniform elasticity when the flux drawn from the end of the flux needle is transported onto the pattern of the substrate. Force 'so will stand out consistently. Thus, by pressing one of the soldering lance needles in a pattern group on the substrate one by one (eg, the smallest unit group in the substrate), those flux needles will be consistent for substantially the same amount of time. The elastic contact force acts on the pattern. Thus, the flux drawn by the end of the flux needle is placed on the pattern of the substrate at / predetermined dose. Each of the springs exerts an elastic force on the pressing member to cause the pressing members to be pressed outwardly to those of the assisting flux needles corresponding to a pattern group or groups of patterns. Thus, the conventional problem of protruding length and the difference between the standing force and 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 flux needle further includes a spring support plate having a predetermined stroke from the body. The spring support plate is assembled on the opposite side of the body where the flux pins are located. So, 1334365

File; TW4142F has a bending stiffness of #. Thus, in the case where the flux needle has to be made fine to match the fine pattern on the substrate, since the flux needle made of stainless steel has high deformation rigidity, the flux needle can still be reliably and repeatedly long-term. Use without replacement. Flux needles made of stainless steel have a rougher surface roughness after the cutting process than flux pins made of bronze. 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 repair can be stably obtained by the agregating effect in the surface tension principle. More flux. Further, the flux needle includes a head part, a body part, and a flux pickup part. The head is located inside the flux tool. The body portion has a cross-section that is smaller than the cross-section of the head portion that extends from the head and is selectively and partially exposed through the through-hole of the flux tool to be exposed outside of the flux tool. The cross section of the flux scooping portion is smaller than the cross section of the main salvage portion, and the flux scooping portion is extended from the main body portion and has at least one projecting portion which is located at the end portion in the long sleeve 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 smaller than the straight diameter of the through hole. Therefore, the main body portion and the coal-feeding agent extraction portion are exposed to the outside. The center line of the head, the center of the main jaw, and the center of the flux extraction unit are located on a common line, so that the flux is easily placed on the substrate. twenty one

In order to make the above description of the present invention more comprehensible, the following detailed description of the present invention will be described in detail with reference to the accompanying drawings in which: FIG. The omission of the structure is to make the gist of the present invention clearer. The following is a description of the flux tool 100 of the first embodiment of the present invention. A flux tool according to a first embodiment of the present invention as shown in Figures 13 to 17. The flux tool includes a case 〇, a position hole 112, a cover i2 〇 and three flux pin blocks 130. The casing 110 has a receiving space 26 1334365

File: TW4142F (accommodating space)ll. The positioning hole 112 is for fixing to the feeding unit of the plant 2. The outer cover covers m to cover the accommodating space (1). The needle block 13 is housed in the accommodating space (1) and is used to elastically kiss the flux needles arranged in correspondence with the pattern 21 of the substrate 2〇. Wherein, when those helper heads 132 corresponding to a pattern group 22+ minimum unit are cut or pressed by pressing 70 pieces 133, in case any U, the 烊刈 needle head 132 contacts the pattern to the shell before the other flux needles 132 > 1 indicates that all of the flux needles are substantially in contact with the two materials at the same time - so that the predetermined dose of flux can be reliably transported from the end of the soldering it 132 (4). In addition, the flux can avoid deformation during the process of transporting the flux. The 11G has two positioning holes 112' precisely arranged with strict tolerances to allow the ball placement machine to more precisely control the placement of the flux tool. Further, a fixing grGQve uia is formed on the side wall of the cavity 1 to 11 to fix the position of the flux pin block 131. The cover 120 has two openings for exposing the flux 丨 32 of the flux pin 131 and opening for fixing the casing. The assisting agent needle 13 includes an outer plate 131, a plurality of flux pins 132, a plurality of pressing members, a plurality of coil springs 134, a guide = iπ, a spring positioning plate 136, and a spring supporting plate 137. The outer panel i3i 2 has a plurality of through holes which are arranged corresponding to the pattern 1 of the wafer or substrate 2 . The head of the flux needle 132 is located below the outer panel 131 and the body portion of the flux needle 132 is located in the through hole 131a. The pressing element forms a quadrilateral cylinder and correspondingly contacts the flux needle for use by 27 1334365 « *

File: TW4142F The through hole 131a presses the flux needle outward. The coil spring 134 is used to generate an elastic force to cause the flux needle to protrude outward, and a portion of the coil spring 134 is located in the deep groove 133a of the pressing member 133. The guiding block 135 has a plurality of guiding holes 135a for guiding the dust removing member 133 by the guiding holes 135a. A spring support piate 136 has a plurality of positioning holes 136a' for the coil springs 134 to pass through. The spring support plate 137 is fixed to the guide block 135 and is used to support the 0 coil spring 134. The head of the flux needle 132 is located all the time below the outer panel 131, and the body portion of the flux needle 132 is selectively exposed to the through hole 131a. As shown in Fig. 24, each pressing member 133 has a pressure receiving surface 133b and a deep groove 133a. The pressing member 133 is for pressing against a corresponding one of the pattern groups 22, and the outside of the pressure receiving surface 133b is a quadrangle corresponding to the pattern group 22. The side wall of the cylinder extends out of the projection φ pr, and the projection 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 the pressure sensitive member is pressed against the aid agent needle corresponding to one pattern group 2^*, the pressing member can be manufactured as long as the movement of the flux needle is ensured to be linearly moved. It can be pressed in the form of those flux pins corresponding to some of the pattern groups. Each of the coil springs 134 is disposed between the pressing member 133 and the elastic yellow supporting plate 137 by a predetermined length. Among them, the coil spring 134 28 1334365

FiIe: TW4142F - the end is inserted into the deep groove 13 of the pressing member 133 as it is, and the other end of the spiral 134 is in contact with and supported by the spring supporting plate 137. n

The guiding block 135 has a plurality of guiding holes, which are arranged in the component 133. The guiding block 135 is formed to have a suitable thickness so that the guiding hole 135a can guide each of the pressing members 133 to move. That is, when the pattern 21 of the substrate 20 becomes fine and arranged in a mutual arrangement, the pressure receiving surface 133b also becomes small, and the movement of the pressing member must be straight to avoid the flux needle 132 and the through hole. Interference, and the protrusion length of the flux needle 132 must be maintained at 3 degrees. Therefore, the length h2 of the pressing member 133 should be longer than the thickness H' of the guiding block 135. Thus, before the helper needle 132 contacts the through hole 131, each of the pressing members 133 first contacts the guiding block 135a, wherein the interference between the flux needle and the through hole 131 of the outer plate 131 is substantially It is possible to avoid the deformation of the 'thus' flux needle 132 from being avoided. Further, the spring support plate 137 is fixed to the bottom surface of the guide block 135 by a screw 136c. Wherein, the two side faces 13 of the spring support plate 137 have a bend. Therefore, the bending length determines the compression length of the coil spring 134 in addition to the moving distance of the pressing member. In addition, the magazine support plate 137 is fixed to the bottom surface of the guide block 135 to support the spiral cage. By attaching the outer panel 131 to the top surface of the guiding block 135, the flux pin 132, the pressing member 133 and the coil spring 134 are placed in a suitable position around the guiding block by the spring supporting plate 137. It is fixed to the bottom surface of the guiding block 135 and the spring positioning plate 136 is disposed therein. Then 29 1334365

f Λ File: TW4142F Each flux pin block 130 is a module, and the handling and assembly of the parts 131~137 will be simpler. ' As electronic devices become smaller, the integration of electronic components becomes higher. In order to cope with this tendency, the pattern 21 of the substrate 20 is arranged more and more densely and closer to each other. The guide hole 135a of the guide block 135 as shown in Fig. 15 requires a smooth inner surface so that the pressing member 133 can move linearly. Therefore, the guide hole 135a is generally formed by a mechanical cutting process. However, the mechanical cutting process has a small and deep guiding hole 135a which has its * limitation. In order to guide the pressing member linearly, the guide hole 135a is made as deep as possible. Therefore, the following is a flux tool 100' of the second embodiment of the present invention, the flux tool 100 having a guiding block 200' the guiding block 200 can be economically and easily fabricated, and the guiding hole of the guiding block 200 Arranged more densely and closer.

The body has a body 210 as shown in Figures 9-21. The cleave has a hollow through portion 210a, and the through portion 21a is located in the clip.卩 position. A lattice structure 220 is staggered at right angles 31 1334365

A guide hole 223 is formed between the staggers, and the guide hole 223 is used to guide the pressing member 133. The body 20 has a plurality of slots formed in the side walls of the through portion 210a such that the ends of the first sheet and the ends of the second sheet are inserted into the slots. In addition, four bolt holes (screw ho 1 e) 213 are formed on the top surface of the body 210 to fix the outer plate 131 to the top surface of the body 210. Four bolt holes (not shown) are formed on the bottom surface of the body 210 to fix the spring support 137 to the bottom surface of the body 210. Further, two holes (not shown) are formed on the bottom surface of the body 210 with strict tolerances with respect to the reference side, and the positioning pins 112' can be inserted into the holes. In addition, bolt holes (not shown) are formed on the bottom surface of the body 210, and the bolt holes are used to fix the guide block 200 to the tool body 110'. In order to form the lattice structure 220 by the interlacing of the first thin plate 221 and the second thin plate 222, as shown in Fig. 22, a plurality of accommodation slits 221a, 222a are formed at a depth of w along the plane direction. The first thin plate 221 is inserted into the second thin plate 222 by the accommodating slit. Therefore, the lattice structure 220 can be easily assembled by inserting the first thin plate 221 into the accommodation slit 222a of the second thin plate 222. Simultaneously, the second thin plate 222 is inserted into the receiving slit 221a of the first thin plate 221 to form a plurality of guiding holes 223, and the guiding holes 223' are surrounded by the first thin plate 221 and the second thin plate 222.

Further, the guiding hole 223 is formed by the first thin plate 221 and the first 32 1334365

* # File: TW4142F Two thin plates 222 are interleaved. If the guide block 200 is to be manufactured in cooperation with a sheet having a high degree of ', a deep guide hole 223 can be manufactured easily and quickly. On the other hand, the guide block 200 is simply assembled by the pieces 131 to 137 as shown in Fig. 16. Wherein, when the upper surface of the lattice structure 220 is in contact with the lower surface of the outer panel 131, when the lower surface of the lattice structure 220 contacts the end surface of the bent portion of the spring support plate 137, although the lattice structure 220 is not bonded by The manner or welding method is combined with the body 210, but the position and assembly state of the lattice structure can be maintained at all times. However, if it is for the convenience of control, the lattice structure can also be selected in a combined manner. By controlling the thickness t of the first thin plate 221 and the second thin plate, the guide block 220 can form a guide hole 223 corresponding to the arrangement of the pressing members 133. By controlling the positions of the accommodating slits 221a, 222a of the thin plates 221, 222, the dimensions X, y of the guide holes 223 can also be controlled.

File: TW4142F. 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 allows the dog to allow inconsistent top and bottom surfaces, the receiving slit 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 w of the slats 221a, 222a is preferably as deep as possible. As shown in Fig. 25, the flux needle is applied to the auxiliary aid tools 100, 100' 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 in the φ portion of the flux pin block 13〇, 2〇〇, and receives the elastic force of the pressing member 133 so that the flux capturing portion 232c protrudes from the 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 arranged corresponding to the pattern 21 of the substrate 2'. The main body portion 232b needs to have a high deformation rigidity to avoid deformation of the flux pin. Therefore, under consideration of the alignment error of the flux needle 232, the direct control of the main body portion 232b is determined without interfering with the through holes 131& of the outer panel 131. The diameter of the flux pad 232c can be used to place the flux on the 34 1334365 ♦ t

Nie: TW4142F The pattern 21 of the substrate is placed within '110% of the diameter D2 of the pattern 21. • That is, as shown in Fig. 26, the projecting portion 232d protrudes into a cylindrical body, and the projecting portion 232d is located on the flux extracting portion 232c on the end surface 232y of the long direction of the flux needle 232. The diameter D4 of the projecting portion 232d is approximately 1/3 of the diameter D3 of the flux scooping portion 232d, and the length h of the projecting portion 232d is also approximately 1/3 of the diameter D3 of the flux scooping portion 232d. That is to say, although the figure 26 exaggerates the shape of the projecting portion 232d_ to make the shape of the projecting portion 232d easy to understand, the diameter and length of the projecting portion 232d are actually 26th. The picture is still small. Further, as shown in Fig. 26, by the surface tension of the flux 88, the flux 88 fills the space 232x between the end surface 232y and the side wall 232da of the overhang portion 232d, as shown in Fig. 27, Portion 232d can draw more flux. The flux needle 232 is made of stainless steel. Although flux pins conventionally made of bronze can be plated or coated to avoid surface corrosion. However, there are disadvantages in that the manufacturing is complicated and the drawing ability is lowered due to the inconsistent plating thickness. The flux needle 232 of the present invention is made of stainless steel having high deformation rigidity, and even if the thickness of the flux needle 232 is fine, the flux needle 232 can be reliably and repeatedly used for a long period of time without deformation. Further, since the non-recording steel material itself has the button-proof property, the flux needle 232 can be easily manufactured by mechanical processing and does not require an electroplating process or a coating process. Therefore, compared to the cause of unevenness 35 1334365

File: TW4142F The flux needle 232 is capable of drawing more flux 88 in the case of conventional flux pins that result in low drawability. As compared with the flux needle made of bronze, as shown in Fig. 26, the flux needle made of stainless steel can have a rough surface roughness due to its high mechanical strength.

Specifically, the surface of a flux needle conventionally manufactured by mechanical cutting is relatively smooth. However, the smooth surface on the flux needle does not help the flux extraction. Therefore, conventional flux needles cannot extract a sufficient amount of flux. However, the material of the flux-welding needle of the present invention has a rough surface roughness because it is made of a high-strength unrecorded steel material. Even if the flux is extracted by the thinner flux extracting portion 232c, a sufficient amount of flux can be taken on the couch, and even a low-viscosity water-based fluxing agent can be taken. That is, the flux probe of the present invention has at least one projecting portion 232d' protruding portion 232d located at the end face 232y of the flux needle and having a rough surface roughness. The flux obtained is filled in a spherical or hemispherical shape = filled in the end surface 232y and the protruding portion 232 (the space between the two, so that the two-needle can support the maximum amount of flux. The flux needle can The flux is suitable for the flux 'whether the flux is a high viscosity oily flux or a low-claw flux. Figures 28 and 29 are applied to the auxiliary agent as shown in Figure π. The outer side view of the flux picking portion of the flux needle of the tool. Further, the protruding portion 232d is formed in a cylindrical shape on the end surface 232y of the soldering needle, as shown in Fig. 28, the protruding portion 232d Can be a 36

*File: TW4142F • The shape of the scorpion is formed. The smaller the traverse of the columnar body is from the end surface. Further, as shown in Fig. 29, a projecting portion 232d can be formed in a first-order polymorphic shape, and P has more than one step surface 232db" on the ladder-shaped column. That is, as long as Filling the extracted flux, by the surface tension principle, can fill the space 232 位于 between the end face 232y of the flux needle and the protruding portion, in which case the protruding portion can be any shape The fluxing needle having the above-mentioned protruding portions 232d, 232d, 232d, can take a larger amount of the helping agent to fill the end plate 2 kiss plate extending portions 232d, 232d, 232d, The space between the side walls 2, 2, /, 232da". According to the present invention, if the pattern 21 of the substrate 2 is more fine and denser to each other, the flux needle can be made finer. Since the flux needle of the present invention has high deformation rigidity, it is possible to easily and quickly manufacture a flux needle having a maximum amount of flux. Φ Turning to the flux tool and the flux needle of the ball ball machine disclosed in the above embodiments, the multi-jg i has the following advantages: The advantage of the eve item 'The following only some advantages are explained - Shuming provides the 焊 flux guard, The pattern for placing the flux on the substrate includes a plurality of pattern groups, and the pattern group is composed of a plurality of patterns.

The spring is used to press against the tree, ::= some: those flux pins in the upper pattern group are pushed to weld: enough to touch the pattern of the substrate. Even when the pattern of the substrate is re-integrated, even in the case where the flux needle is more than the other flux needles: the consistently long sounds, standing 'forces, still make enough The thickener can be placed on the elastic bend:: The flux can avoid the No. 2 curve and the cross shape of the flux needle during the operation, because before the flux needle contacts the outer plate, the house component will first Touching the inside surface of the guide hole: The solder pin of the second can be used reliably and repeatedly for a long time. Further, the present invention provides a simple structure. The 7L member has a deep groove, and therefore, the second degree of the paste becomes shorter due to the existence of the accommodating groove.

Especially in the case where the patterns of the substrate are very fine and densely arranged, the present invention can easily manufacture a low-cost guide block which guides each pressing member by the guiding hole (for example) : corresponds to a pattern group). Further, by easily controlling the height H of the first thin plate and the second thin plate so that the first thin plate and the first thin plate have sufficient sizes, the present invention can provide a deep guide block having a deep guide block having a deep The guide hole is thus able to guide the pressing member steadily to minimize the possibility of interference between the flux needle and the through hole of the outer plate. In addition, the present invention provides a flux needle characterized in that the flux needle is at least one extension, the cross section of the protrusion is smaller than the area of the end surface 232y of the flux needle, and the extension is used for a larger amount of assistance. The flux is drawn into the space 232x between the overhang portion and the end surface 232y, and the flux is molded in a spherical or hemispherical shape by the surface tension of the φ flux. The present invention also provides a flux needle. The flux needle is made of stainless steel. Stainless steel has high deformation resistance and a rough surface roughness that maximizes the fluxing effect of the flux. Flux needles made of stainless steel draw more flux than conventional bronze flux needles. This is not the case even if the thickness of the flux needle has to be made thinner in order to match the densely arranged patterns. Further, according to the present invention, the flux needle is made of stainless steel, and the stainless steel has excellent corrosion resistance. Therefore, the flux needle does not need 39 1334365 »
