Description

Technical Field

[0001] The utility model relates to the technical field of semiconductor packaging, in particular to a fixture for a packaging carrier board and a transmission system. Background Technique

[0002] At present, the development and progress of technology are inseparable from the support of integrated circuits. IC (Integrated Circuit) carrier boards are widely used in various electronic devices and are high-end products with relatively high technical difficulties in the PCB (Printed Circuit Board) industry. During the packaging process, as a key material in packaging, the IC carrier board is located between the chip and the PCB, realizing signal transmission and connection, providing protection and support for the chip, and forming a heat dissipation channel, so that the packaged chip reaches the required size. Since the IC carrier board can improve the stability and reliability of integrated circuits, it has become an indispensable part of various electronic devices, with an increasing demand and very broad development prospects.

[0003] Compared with ordinary PCBs, IC carrier boards have the characteristics of thinner board bodies, finer line widths and line spacings, and smaller hole diameters. The traditional Subtractive production process has been unable to achieve this, thus giving rise to new production processes: SAP (Semi-Additive Process) or mSAP (Modified Semi-Additive Process). This process is a semi-additive process based on graphic electroplating. The SAP or mSAP process can use a very small amount of etching to produce circuits, solving the difficulties of the traditional subtractive method in the production of fine circuits. The production process of SAP or mSAP includes: laser drilling → desmearing + electroless copper plating → pretreatment → laminating → exposure → vertical development → graphic electroplating copper → stripping → flash etching → graphic inspection.

[0004] Different from the horizontal development in the conventional Subtractive process, the IC carrier board can be horizontally transported through the rotation of rollers. In the SAP or mSAP process, since graphic electroplating needs to be carried out after development, and because the dry film is easily scratched or abraded, the contact of rollers on the board surface needs to be minimized as much as possible. Therefore, vertical development is involved, that is, the circuit board passes through the development tank in the vertical direction. Due to the lack of roller support, fixtures are required in the production process to enable the IC carrier board to be vertically erected and transported along the left and right directions of the product.

[0005] Such as Figure 1As shown, the fixture 1 in the prior art includes a rectangular frame 10, two hooks 11, and two bottom plates 12. The rectangular frame 10 includes a horizontal parallel bar 100 and a vertical parallel bar 101. A plurality of fixing components A are provided on the horizontal parallel bar 100, and the fixing component A includes a clamping point 100a for fixing the IC package substrate. The two hooks 11 are respectively arranged at the positions where the upper ends of the vertical parallel bars 101 of the rectangular frame 10 contact one of the horizontal parallel bars 100; the hooks 11 are connected to a chain 15, and the free movement of the hooks 11 on the upper track 13 is controlled by the chain 15; the two bottom plates 12 are respectively arranged at the positions where the lower ends of the vertical parallel bars 101 of the rectangular frame 10 contact the other horizontal parallel bar 100, and free movement on the lower track 14 is achieved through the balls on the bottom plates 12. However, this fixture 1 has the following problems:

[0006] 1) The upper and lower horizontal parallel bars 100 are relatively short. Especially, the upper horizontal parallel bar 100 is subjected to a large force. During the transmission of the IC package substrate, as Figure 2 shown, the clamping points 100a on the upper horizontal parallel bar 100 often get damaged, resulting in the scrapping of the IC package substrate.

[0007] 2) After the IC package substrate undergoes vertical development, as Figure 3 shown, the residual liquid medicine 100b at the clamping points 100a is not easily dried, and residual marks often appear, contaminating the surface of the IC package substrate. During the electroplating step, anti-plating occurs, resulting in various defects in the finally etched IC package substrate, such as open circuits, notches, or bottom copper breakage, etc., causing the scrapping of the IC package substrate, low yield, and increased costs.

[0008] Therefore, it is necessary to optimize and improve the fixture for the IC package substrate to further avoid defects such as board damage, open circuits, and notches, and reduce the scrapping probability.

[0009] It should be noted that the above introduction of the technical background is only for the convenience of clearly and completely explaining the technical solution of the present invention and facilitating the understanding of those skilled in the art. It cannot be considered that the above technical solutions are well-known to those skilled in the art just because these solutions are described in the background art part of the present invention. Summary of the Invention

[0010] In view of the above-mentioned disadvantages of the prior art, the purpose of the present invention is to provide a fixture and a transmission system for the package substrate, which are used to solve the problems in the prior art that the clamping points on the upper horizontal parallel bar often get damaged, resulting in the scrapping of the positive film of the product. At the same time, there are also problems such as open circuits, notches, or bottom copper breakage, etc., causing the scrapping of the product, low yield, and increased costs.

[0081] As Figure 4 shown, this embodiment provides a fixture 2 for an encapsulation carrier board, including: a support member 20 and a rectangular main body 21.

[0082] As Figure 4 shown, the rectangular main body 21 includes 2 vertical tie rod fixing components 210 for fixing the encapsulation carrier board and 2 horizontal tie rod components 211. Support members 20 for supporting each vertical tie rod fixing component 210 and each horizontal tie rod component 211 are provided at the 4 corners of the rectangular main body 21.

[0083] Specifically, in this embodiment, the support member 20 includes a hook 200 and a base 201; the hook 200 is disposed at two corners above the rectangular main body 21; the base 201 is disposed at two corners below the rectangular main body 21. That is, the hook 200 is disposed at the intersection of the upper end of each vertical rod fixing member 210 and one of the horizontal rod members 211; the base 201 is disposed at the intersection of the lower end of each vertical rod fixing member 210 and the other horizontal rod member 211. The hook 200 and the base 201 support each vertical rod fixing member 210 and each horizontal rod member 211. At the same time, as Figure 5 shown, a stop bar 200a with an oblique angle α of 45° for clamping the chain 22 is provided at the front end position of the hook 200. In actual use, any angle of the stop bar that can clamp the chain is applicable to the present invention, and will not be elaborated here one by one. A ball 200b is provided at the rear end position and is matched with the chain 22, so that the hook 200 can be driven by the chain 22 to move on the upper track 23. A ball is also provided at a position near the bottom of the base 201 to facilitate sliding in the lower track 24. The hook 200 and the base 201 support and drive the entire encapsulation carrier board hanger 2 to move freely on the track, enabling the encapsulation carrier board to be transferred in the left-right direction, further preventing the encapsulation carrier board in the encapsulation carrier board hanger 2 from contacting foreign objects and being scratched, and reducing the probability of the board being damaged and scrapped. In actual use, any device that can drive the hanger 2 to move freely left and right on the track is applicable to the present invention, and will not be elaborated here one by one.

[0084] As an example, a plurality of fixing members B for fixing the encapsulation carrier board are provided on the vertical rod fixing member 210. An enlarged schematic diagram of one of the fixing members B is as Figure 7 shown. Each vertical rod fixing member 210 includes 2 rods 210a, and the 2 rods 210a are connected by a first connecting member 25. The first connecting member 25 is set as a control clip, and an appropriate pressure is applied to the 2 rods 210 by the control clip to ensure stable fixation. At the same time, in order to shorten the time required for the process, the opening and closing degree and the applied force of the control clip are controlled by a host computer (not shown) to control the opening and closing degree of the 2 rods 210a, further achieving the purpose of fast response, improving the assembly efficiency and accuracy. As Figure 9As shown in the figure, N protruding members 210b for fixing the encapsulation carrier board are oppositely arranged on each pull rod 210a, where N is a natural number greater than or equal to 1. The protruding members 210b are welded to the pull rods 210a by welding, so that the protruding members 210b can be more stably fixed on the pull rods 210a. In actual use, any method that can fix the protruding members on the pull rods is applicable to the present utility model, and will not be elaborated one by one here. That is, one surface of the pull rod 210a with the protruding member 210b is oppositely arranged face to face with the surface of another pull rod 210a with the protruding member 210b to fix the encapsulation carrier board.

[0085] As another example, a plurality of fixing components B for fixing the encapsulation carrier board are arranged on the vertical pull rod fixing component 210. Another enlarged schematic diagram of the fixing component B is shown in Figure 8 As shown in the figure, each vertical pull rod fixing component 210 includes 4 pull rods 210a, and the 4 pull rods 210a are respectively 2 left pull rods and 2 right pull rods. As shown in Figure 8As shown, N protruding members 210b for fixing the encapsulation carrier board are oppositely arranged on each of the two pull rods on the right side, and the surfaces of one of the pull rods 210a with the protruding members 210b are arranged face to face with the surfaces of the other pull rod 210a with the protruding members 210b. The left pull rod and the right pull rod are connected by a second connecting member 26; threaded holes 260 are arranged on the back surfaces of the protruding members 210b of the two pull rods on the right side, and threaded holes 260 are also arranged on the two pull rods on the left side. The stainless steel copper sheets 261 with threaded holes at both ends are placed on the left and right pull rods, and the threaded holes on the stainless steel copper sheets 261 are in one-to-one correspondence with the threaded holes 260 on the left and right pull rods to fix the left and right pull rods into one body. In actual use, any device that can fix the left and right pull rods into one body is applicable to the present utility model, and will not be elaborated one by one here. And there is a certain distance between the left and right pull rods (i.e., the length of the stainless steel copper sheet 261) to fix encapsulation carrier boards of different sizes. In actual use, the distance between the left and right pull rods is set according to the size of the encapsulation carrier board, and will not be elaborated one by one here. The two pull rods on the left side are connected by a first connecting member 25. The first connecting member 25 is set as a control clip, and an appropriate pressure is applied to the two pull rods 210a on the left side through the control clip to ensure stable fixation. In actual use, any device that can control the opening and closing of the two pull rods on the left side is applicable to the first connecting member of the present utility model, and is not limited to this embodiment. At the same time, in order to shorten the time required for the process, the opening and closing degree and the applied force of the control clip are controlled and adjusted by the upper computer to open the two pull rods on the right side, move the encapsulation carrier board into the encapsulation carrier board hanger 2, and then control the control clip by the upper computer to merge the two pull rods on the left side, so that the encapsulation carrier board is fixed in the encapsulation carrier board hanger 2, further achieving the purpose of fast response, improving the assembly efficiency and accuracy. In actual use, the number of pull rods includes but is not limited to 2 and 4, and will not be elaborated one by one here.

[0086] More specifically, in this embodiment, as Figure 6As shown, after the packaging carrier plate completes the vertical development operation, it needs to be placed on a horizontal tabletop and then transferred to the carrier tray. At this time, residual liquid medicine 210c will still remain at the position of the protruding part 210b on the vertical pull rod fixing part 210, contaminating the surface of the packaging carrier plate and causing the packaging carrier plate to be scrapped. Therefore, the protruding part 210b is set as a circular protruding part to minimize the contact area with the packaging carrier plate as much as possible. In actual use, the shape of the protruding part can be set arbitrarily according to needs, which will not be elaborated one by one here. The diameter L1 of the circular protruding part is set to 3 mm to 8 mm, such as 4 mm, 5 mm, 6 mm, 7 mm. In actual use, the diameter of the circular protruding part can be set arbitrarily according to needs, which will not be elaborated one by one here. M grooves 210d are provided on each circular protruding part, where M is a natural number greater than or equal to 1. The width H1 of the protruding area between two adjacent grooves 210d is set to 0.5 mm to 1.5 mm, such as 0.7 mm, 0.9 mm, 1.1 mm, 1.4 mm. In actual use, the width of the protruding area is set based on the diameter of the circular protruding part and is not limited to this embodiment. By providing a plurality of grooves 210d on the circular protruding part, the contact surface between the protruding part 210b and the packaging carrier plate is set as a line contact, thereby reducing the contact area and further reducing the residual liquid medicine between the protruding part 210b and the packaging carrier plate.

[0087] More specifically, in this embodiment, since the main component of the liquid medicine in the vertical developing line is a sodium carbonate alkaline solution with a concentration of about 1%, the rectangular main body 21 is set as a stainless steel rectangular main body resistant to alkaline liquid medicine corrosion; in actual use, any material resistant to alkaline liquid medicine corrosion is applicable to the rectangular main body of the present utility model, which will not be elaborated one by one here.

[0088] More specifically, as Figure 9 shown, in this embodiment, since the packaging carrier plate is an ultra-thin circuit board with a thickness of about 0.08 mm to 0.2 mm, or even thinner, and the protruding part 210b on the stainless steel rectangular main body is set as a stainless steel protruding part. When this stainless steel protruding part contacts the packaging carrier plate, on the one hand, there is a risk that the packaging carrier plate will be clamped and damaged, and on the other hand, since the material of the protruding part 210b is a metal material, when the packaging carrier plate is too thin, there will also be a risk that it cannot be clamped and the packaging carrier plate will slip. Therefore, a rubber coating 210e with alkali resistance is provided on the surface of each protruding part 210b to increase the friction between the rubber coating 210e and the packaging carrier plate, and further effectively reduce the risk of damage and easy slipping of the packaging carrier plate. In actual use, any device that can prevent the packaging carrier plate from slipping and has alkali resistance is applicable to the present utility model, which will not be elaborated one by one here.

[0089] As Figure 10As shown in the figure, the present utility model further provides a transmission system 3, which is used to place the packaging carrier in the packaging carrier fixture 1 for vertical development, and the packaging carrier fixture 2 provides support for the packaging carrier 30. The transmission system 2 includes the packaging carrier 30 and the packaging carrier fixture 2.

[0090] As Figure 10 shown in the figure, the packaging carrier 30 is fixed on the rectangular main body 21 by two vertical fixed pull rod components 210 for vertical development. That is, by controlling the closing of the first connecting piece 25 by the upper computer, the two pull rods on the right with protruding parts 210b are also closed, so that the edge of the packaging carrier 30 is in close contact and fixed with the protruding parts 210b on the vertical fixed pull rod component 210. And since there are a plurality of grooves 201d on the protruding part 210b, the contact between the protruding part 210b and the packaging carrier 30 is a line contact, that is, the contact area between the protruding part 210b and the packaging carrier 30 is reduced. At the same time, in order to strengthen the stable fixation of the packaging carrier 30 in the fixture, a rubber coating 201e is set on the surface of the protruding part 210b to increase the friction with the packaging carrier 30 and prevent the packaging carrier from slipping.

[0091] As another implementation manner of the present utility model, the specific steps of moving the packaging carrier 30 into the packaging carrier fixture 2 (based on Figure 8 the scheme shown in the figure) are as follows:

[0092] S1. Control the upper computer to separate the two pull rods on the left through the first connecting piece 25, and drive the two pull rods on the right to separate through the stainless steel copper sheet 261.

[0093] S2. When the packaging carrier 30 reaches the set position (on the rectangular main body 21), the upper computer controls the first connecting piece 25 to merge the two pull rods on the left, and drives the two pull rods 210a on the right to merge through the stainless steel copper sheet 261, so that the protruding part 210b is in close contact and fixed with the packaging carrier 30.

[0094] S3. Perform a vertical development operation. After the vertical development operation is completed, replace the next packaging carrier 30, and repeat steps S1 to S2.

[0095] In summary, the present utility model provides a fixture and a transmission system for a packaging carrier board. The fixture for the packaging carrier board includes: a support member and a rectangular main body; the rectangular main body includes two vertical rod fixing members for fixing the packaging carrier board and two horizontal rod members; the support members for supporting the respective vertical rod fixing members and the respective horizontal rod members are provided at the four corners of the rectangular main body. The present utility model adjusts the position of the protruding member on the fixture for the packaging carrier board: from the original upper and lower sides to the left and right sides, thereby reducing the problem of board damage caused by uneven stress on the upper and lower sides. And the protruding member is set as a circular protruding member, the diameter of the circular protruding member is set between 3 mm and 8 mm, reducing the contact area between the protruding member and the packaging carrier board; at the same time, a groove is provided on the circular protruding member, so that the contact surface between the circular protruding member and the packaging carrier board becomes line contact one by one, further reducing the contact area between the protruding member and the packaging carrier board. A layer of rubber coating is also provided on the surface of the protruding member of the fixture for the packaging carrier board to prevent the packaging carrier board made of metal from slipping due to being too thin. And the fixture for the packaging carrier board of the present utility model has a simple design and is convenient to operate. Therefore, the present utility model effectively overcomes various disadvantages in the prior art and has high industrial utilization value.
