Description

Technical Field

[0001] This utility model relates to the field of circuit board production equipment technology, and in particular to a substrate fixture for fixing a substrate and a substrate device having the substrate fixture. Background Technology

[0002] Please see Figure 13 As shown, in the semiconductor industry, a circuit board 100 can have multiple circuits. To accommodate the various manufacturing processes required for the circuit board 100, it needs to be transported online on the production line. Based on the requirement for online transport of the circuit board 100, these circuits are configured and placed in multiple circuit placement areas 101 on the circuit board 100. Furthermore, to accommodate the transport method of the circuit board 100, areas where circuits are not planned are designated as multiple inactive areas 102. Currently, a common arrangement method in the industry is... Figure 13 As shown, three invalid areas 102 and two circuit setting areas 101 are spaced apart from each other.

[0003] Considering the substrate thickness D of the circuit board 100, three different transport methods are commonly used in the industry for transporting the circuit board 100. For circuit boards 100 with a substrate thickness D greater than 0.4 mm, the circuit board 100 has sufficient structural rigidity and is therefore not easily deformed by external pressure. However, for circuit boards 100 with a substrate thickness D less than 0.4 mm, the structural rigidity of the circuit board 100 is weaker, and therefore it is more easily deformed by external pressure. Based on this, circuit boards 100 with a substrate thickness D greater than 0.4 mm are suitable for transporting circuit boards 100 with a substrate thickness D greater than 0.4 mm. Figure 14 The horizontal conveying method shown is a three-point roller, or as... Figure 15 The shown is a clamp-type horizontal conveying method, and the circuit board 100 with a substrate thickness D of less than 0.4 mm is suitable for applications such as... Figure 16 The diagram shows a horizontal conveying method using densely packed rollers.

[0004] Please see Figure 14As shown, the three-point roller horizontal conveying method involves multiple upper rollers 103 and multiple lower rollers 104 applying stress to opposite sides of the circuit board 100 to clamp it, and then conveying the circuit board 100 through the rotation of the upper rollers 103 and lower rollers 104. The upper rollers 103 are arranged in three rows, and the lower rollers 104 are also arranged in three rows corresponding to the upper rollers 103. The upper rollers 103 and lower rollers 104 only contact the three inactive areas 102 of the circuit board 100; therefore, the two circuit placement areas 101 of the circuit board 100 do not contact any rollers, thus ensuring that the circuits within the circuit placement areas 101 are not subjected to stress compression.

[0005] However, if the circuit board 100 with a thickness D of less than 0.4 mm is transported using this three-point roller horizontal transport method, the circuit board 100's insufficient rigidity will prevent it from being supported by only three points and kept on the same plane. Consequently, deformation of the circuit board 100 will cause damage to the board holder during transport. Therefore, the circuit board 100 with a thickness D of less than 0.4 mm cannot be transported using the three-point roller horizontal transport method.

[0006] Please see Figure 15 As shown, the horizontal conveying method using a clamping frame involves a hollow clamping frame 105 clamping the circuit board 100 in the center of the hollow clamping frame 105 by multiple clamps 106, and then transporting the hollow clamping frame 105, which holds the circuit board 100, in a moving direction MD by a track. The clamps 106 contact the ineffective areas 102 of the circuit board 100 and apply stress to these ineffective areas 102, but the clamps 106 do not contact the circuit arrangement areas 101 of the circuit board 100.

[0007] However, similarly, if the circuit board 100 with a thickness D of less than 0.4 mm is transported using this clamp-type horizontal conveying method, the circuit board 100 will not be able to be kept on the same plane due to insufficient rigidity. Therefore, the circuit board 100 cannot be smoothly placed in the hollow clamp 105 and fixed stably by the clamp.

[0008] Please see Figure 16 As shown, the horizontal conveying method of the dense rollers applies stress evenly to the opposite sides of the circuit board 100 by the dense upper rollers 103 and the dense lower rollers 104, thereby ensuring that the circuit board 100, whose thickness D is less than 0.4 mm, can be smoothly conveyed even if its rigidity is insufficient due to the support of the dense rollers and the uniform force applied from top to bottom.

[0009] However, the densely packed upper rollers 103 and lower rollers 104 apply stress evenly to the opposite sides of the circuit board 100, meaning that the circuit placement areas 101 will also be subjected to stress compression, just like the ineffective areas 102. Figure 17 As shown, by using a horizontal conveying method with dense rollers, the circuits 107 in these circuit setting areas 101 are easily damaged and defects 108 are generated due to the contact and squeezing of the upper rollers 103 and the lower rollers 104.

[0010] Therefore, it is evident that the current horizontal conveying methods using three-point rollers, clamp-type horizontal conveying, and dense rollers are all unsuitable for conveying the circuit board 100 with a substrate thickness D of less than 0.4 mm. The circuit board 100 with a substrate thickness D of less than 0.4 mm is prone to deformation of the clamping plate or damage to the circuits 107 in the circuit setting areas 101 during transport.

[0075] This utility model provides a substrate fixture and a substrate device having the substrate fixture.

[0076] Please see Figure 1 and Figure 2 As shown, the substrate fixture of this utility model includes an upper fixture unit 10 and a lower fixture unit 20. The substrate device of this utility model having the substrate fixture includes the upper fixture unit 10, the lower fixture unit 20 and a substrate 30.

[0077] The upper fixture unit 10 is provided with multiple engaging structures 11. The lower fixture unit 20 includes a bottom rectangular frame 22, which has a top surface 23 and a bottom surface 24 facing each other, and also has multiple internal spaces 25. The top surface 23 of the bottom rectangular frame 22 is provided with multiple engaging members 21, and these engaging members 21 are correspondingly disposed on the engaging structures 11 on the upper fixture unit 10.

[0078] The engaging members 21 of the lower fixture unit 20 are respectively engaged with the engaging structures 11 of the upper fixture unit 10, and the lower fixture unit 20 and the upper fixture unit 10 are spaced apart to form a substrate accommodating space 31 in a gap between the upper fixture unit 10 and the lower fixture unit 20.

[0079] The substrate 30 is disposed in the substrate receiving space 31 between the upper fixture unit 10 and the lower fixture unit 20. The substrate 30 includes a plurality of circuit setting areas 32 and a plurality of invalid areas 33, the circuit setting areas 32 being spaced apart from each other, and the invalid areas 33 surrounding the circuit setting areas 32.

[0080] Furthermore, multiple through holes 34 are formed in these invalid regions 33, each through hole 34 corresponding to the position of each engaging structure 11 on the upper fixture unit 10 and the position of each engaging member 21 on the lower fixture unit 20. The engaging structures 11 on the upper fixture unit 10 and the engaging members 21 on the lower fixture unit 20, through the through holes 34 in the substrate 30, secure the substrate 30 within the substrate receiving space 31. Thus, the lower fixture unit 20 adheres to the invalid regions 33 of the substrate 30, and exposes the circuit placement areas 32 of the substrate 30 within the frame spaces 25 of the lower fixture unit 20.

[0081] Regardless of whether the thickness of the substrate 30 is less than 0.4 mm, the upper jig unit 10 and the lower jig unit 20 of this invention can securely hold the substrate 30 within the substrate receiving space 31. The bottom rectangular frame 22 of the lower jig unit 20 provides structural support to the substrate 30, thereby enhancing the rigidity of the substrate 30 within the substrate receiving space 31. Specifically, the in-frame spaces 25 of the bottom rectangular frame 22 ensure that the circuit mounting areas 32 of the substrate 30 do not press down onto the bottom rectangular frame 22, thus preventing damage from downward pressure. Simultaneously, because the lower jig unit 20 conforms to the ineffective areas 33 of the substrate 30, it provides support when the ineffective areas 33 of the substrate 30 are subjected to stress and pressed down, thereby strengthening the rigidity of the ineffective areas 33 of the substrate 30. Overall, the rigidified substrate 30 can remain undeformed, warped, or dented during transport on a horizontal plane due to insufficient structural rigidity. Therefore, this invention ensures that, after combining the upper jig unit 10 and the lower jig unit 20, the substrate 30 fixed between the upper jig unit 10 and the lower jig unit 20 can be transported using a three-point roller horizontal transport method or a clamp-type horizontal transport method, and avoids damage to the substrate 30 by the jamming plate or the circuit setting areas 32 of the substrate 30 during transport.

[0082] Figure 1 This diagram presents a partially exploded view of the substrate device of the present invention in the first embodiment, and Figure 2 This diagram presents a schematic representation of the upper fixture unit 10, the lower fixture unit 20, and the substrate 30 after their assembly in the first embodiment. In this embodiment, the bottom rectangular frame 22 of the lower fixture unit 20 further includes a central bottom cuboid 221, two bottom edge cuboids 222, and two bottom auxiliary cuboids 223. The bottom edge cuboids 222 are respectively attached to the two opposite planes of the central bottom cuboid 221, forming an H-shaped bottom structure. The bottom auxiliary cuboids 223 are disposed between the bottom edge cuboids 222 and are parallel to the central bottom cuboid 221. Furthermore, the central bottom cuboid 221 is equidistantly disposed between the two bottom auxiliary cuboids 223. Thus, the bottom auxiliary cuboids 223 assist the H-shaped bottom structure, further enhancing its ability to support the substrate 30.

[0083] Furthermore, the upper fixture unit 10 includes a top rectangular frame 12, which has a top surface 13 and a bottom surface 14 facing each other, and the engaging structures 11 are disposed on the bottom surface 14 of the top rectangular frame 12. The top rectangular frame 12 also has a plurality of internal spaces 15, which also correspond to the circuit arrangement areas 32 of the substrate 30, so as to avoid the top rectangular frame 12 applying weight to the circuit arrangement areas 32 of the substrate 30 and damaging the circuit.

[0084] The top rectangular frame 12 of this embodiment includes a top central cuboid 121, two top edge cuboids 122, and two top auxiliary cuboids 123. The top edge cuboids 122 are respectively attached to two opposite planes of the top central cuboid 121 to form an H-shaped top structure. The top auxiliary cuboids 123 are disposed between the top edge cuboids 122 and are parallel to the top central cuboid 121. Furthermore, the top central cuboid 121 is equidistantly disposed between the two top auxiliary cuboids 123.

[0085] In this embodiment, the substrate 30 is configured to have two circuit setting areas 32 to match existing manufacturing processes. For example... Figure 1 As can be seen, the bottom central cuboid 221, the two bottom edge cuboids 222, and the two bottom auxiliary cuboids 223 together form two inner-frame spaces 25, while the top central cuboid 121, the two top edge cuboids 122, and the two top auxiliary cuboids 123 together form two inner-frame spaces 15, and these inner-frame spaces 15 and inner-frame spaces 25 are all positioned to correspond to the two circuit setting areas 32 of the substrate 30.

[0086] Furthermore, the engaging structures 11 on the upper jig unit 10 are distributed on the top central cuboid 121 and the two top edge cuboids 122, while the engaging members 21 on the lower jig unit 20 are distributed on the bottom central cuboid 221 and the two bottom edge cuboids 222. In this way, the engaging structures 11 and engaging members 21 can be uniformly combined to uniformly enhance the rigidity of the substrate 30.

[0087] Please refer to the following: Figure 3As shown, the top central cuboid 121 and the two top auxiliary cuboids 123 of the top rectangular frame 12 have three rows of channels for the movement of three-point rollers. The three-point rollers refer to the horizontal transport of the substrate device of this invention, which has the substrate fixture, by means of the synchronous rotation of three rows of upper rollers 103 and three rows of lower rollers 104. The upper rollers 103 contact the upper fixture unit 10 and apply stress to it, while the lower rollers 104 contact the lower fixture unit 20 and apply stress to it. The upper fixture unit 10 can evenly distribute force to the ineffective areas 33 of the substrate 30, and the lower fixture unit 20 can evenly distribute force and support the substrate 30. In this way, the rigidity of the substrate 30 between the upper fixture unit 10 and the lower fixture unit 20 can be strengthened, thereby preventing the exposed circuit setting areas 32 from being lifted or sunken by the influence of the upper rollers 103 and the lower rollers 104. This avoids the substrate 30 from being jammed or the circuit setting areas 32 of the substrate 30 from being scratched or damaged during the transfer.

[0088] Please see Figure 4 and Figure 5 As shown, Figure 4 and Figure 5 The diagram presents a cross-sectional view of an engaging structure 11 of the upper jig unit 10 combined with an engaging member 21 from the lower jig unit 20. In this embodiment, each engaging structure 11 of the upper jig unit 10 is a magnetic lock disposed in a blind hole 16 of the upper jig unit 10, and each engaging member 21 of the lower jig unit 20 is a locking pin, which is inserted into and engaged with the magnetic locks.

[0089] Furthermore, in this embodiment, each blind hole 16 of the upper fixture unit 10 has an inner diameter Din and an opening diameter Dop, and the opening diameter Dop is smaller than the inner diameter Din. Each magnetic lock in each blind hole 16 includes an iron ring 111, a spring 112, and two steel balls 113. The iron ring 111 is disposed in the blind hole 16. The spring 112 is disposed between a bottom 161 of the blind hole 16 and the iron ring 111. The two steel balls 113 are disposed between the iron ring 111 and the opening of the blind hole 16. Because the opening diameter Dop of the blind hole 16 is smaller than the inner diameter Din, the two steel balls 113 in the blind hole 16 do not have sufficient space to slide to the opening of the blind hole 16. Furthermore, each of the locking pins of the lower fixture unit 20 is a locking pin 211, and the locking pin 211 is provided with two grooves 212, which match the two steel balls 113 in each of the blind holes 16 of the upper fixture unit 10.

[0090] like Figure 4As shown, when the locking pin 211 is inserted into the blind hole 16 and passes through the iron ring 111, the two steel balls 113 in the blind hole 16 move into the two grooves 212 of the locking pin 211. At this time, the locking pin 211, with the two steel balls 113 engaged, no longer has enough space to slide to the opening of the blind hole 16, that is, the two grooves 212 of the locking pin 211 are locked in the blind hole 16 by the two steel balls 113. Since the spring 112 will press down on the two steel balls 113, the two steel balls 113 will be firmly engaged in the two grooves 212 of the locking pin 211, thereby making the locking pin 211 firmly locked in the blind hole 16, and also making the upper fixture unit 10 and the lower fixture unit 20 firmly engaged.

[0091] like Figure 5 As shown, when attempting to unlock the magnetic lock and remove the locking pin 211 from the blind hole 16, a magnet 17 is placed on the iron ring 111 facing the bottom 161. The magnet 17 magnetically attracts the iron ring 111 and the two steel balls 113, causing the iron ring 111 to compress the spring 112 and the two steel balls 113 to slide away from the two grooves 212 of the locking pin 211. Thus, the locking pin 211, with the two steel balls 113 removed, can be withdrawn from the blind hole 16.

[0092] In one embodiment, the magnet 17 is a permanent magnet. By moving the magnet 17 closer to the bottom 161 of the blind hole 16 at appropriate times, the strength and timing of the magnetic force of the magnet 17 attracting the iron ring 111 and the two steel balls 113 can be controlled and adjusted. Therefore, the magnetic lock can be unlocked by moving the magnet 17 closer to the bottom 161 of the blind hole 16.

[0093] In another embodiment, the magnet 17 is an electromagnet, so the magnet 17 can be electrically controlled to adjust the strength and timing of its magnetic attraction to the iron ring 111 and the two steel balls 113. Therefore, the magnetic lock can be unlocked without moving the magnet 17 close to the bottom 161 of the blind hole 16.

[0094] It should be noted that the magnetic lock described above can automatically lock without the use of electricity. In other words, the two steel balls 113 can slide into the two grooves 212 of the lock pin 211 by being pressed down by the spring 112 without the use of the magnetic force generated by the electromagnet.

[0095] Please see Figure 6 and Figure 7 As shown, in one embodiment of the present invention, the top central cuboid 121, the top edge cuboids 122 and the top auxiliary cuboids 123 of the upper fixture unit 10 are each provided with a plurality of drainage holes 18, and each drainage hole 18 is connected to the substrate 30 in the substrate accommodating space 31.

[0096] like Figure 7 As shown, when the substrate 30, the upper fixture unit 10, and the lower fixture unit 20 are transported by the aforementioned three-point rollers, the rolling upper rollers 103 drive the upper fixture unit 10, the lower fixture unit 20, and the substrate 30 to move in a moving direction MD.

[0097] Preferably, the extending direction of the top auxiliary cuboids 123 is parallel to the moving direction MD, and each of the drainage holes 18 located on the top auxiliary cuboids 123 drains water in a drainage direction FD. An angle θ is formed between the moving direction MD and the drainage direction FD; in other words, the angle θ is greater than 90 degrees and less than 180 degrees between the drainage direction FD and the extending direction of the top auxiliary cuboids 123. This structure facilitates the efficient drainage of chemicals sprayed onto the circuitry areas 32 of the substrate 30 during the process, particularly by being guided by the water flow branches of the drainage holes 18 on the top auxiliary cuboids 123.

[0098] Furthermore, in one embodiment, the top auxiliary cuboids 123 are all flexible waterproof structures. For example, the flexible waterproof structure is made of multi-layered composite materials, with an internal elastic material and a surface material covering the elastic material that is hydrophobic. Therefore, the overall structure can be deformed under pressure while also being hydrophobic. That is, when the upper rollers 103 travel over the top auxiliary cuboids 123, the top auxiliary cuboids 123 are compressed and deformed, thereby squeezing the drainage holes 18 one by one and squeezing out the residual chemicals in the drainage holes 18 along the drainage direction FD, so as to facilitate the replacement of fresh chemicals and achieve better chemical action efficiency and uniformity. Finally, it is beneficial to ensure that the circuit setting areas 32 on the substrate 30 are clean and free of residual chemicals from the process when transferring the substrate 30.

[0099] In one embodiment, the elastic material may be, for example, natural rubber, synthetic rubber, synthetic resin, silicone, thermoplastic elastomer (TPE-S) and SBC (styrene-based), TPO (polyolefin-based), TPV (vulcanizate), TPU (polyurethane-based), TPE-E (polyester-based), or TPE-A (polyamide-based). The hydrophobic material may be, for example, organic synthetic resins such as acrylic acid, epoxy resin, polyethylene, polystyrene, polyvinyl chloride, polytetrafluoroethylene, polydimethylsiloxane, or polyester and polyurethane. The composite material may also be mixed with organic / inorganic materials, such as ceramics, quartz, glass, or clay.

[0100] Please see Figure 8 and Figure 9 As shown, in the second embodiment of this utility model, the structure of the upper jig unit 10 is simplified, that is, the upper jig unit 10 only includes the aforementioned top central cuboid 121 and the two top edge cuboids 122. In this embodiment, the engaging structures 11 are only distributed on the two top edge cuboids 122. However, even without the two top auxiliary cuboids 123, the upper jig unit 10 can still connect with the lower jig unit 20 and sufficiently stabilize the substrate 30 between the upper jig unit 10 and the lower jig unit 20. Meanwhile, even without the two top auxiliary cuboids 123 serving as two channels for the two sets of upper rollers 103 to pass through during three-point roller transport, the substrate 30 below the upper fixture unit 10 can still maintain the circuit setting areas 32 intact. This is because only the ineffective areas 33 of the substrate 30 will contact the upper rollers 103, and these ineffective areas 33 are supported by the lower fixture unit 20 below the substrate 30, providing sufficient rigidity. Therefore, they will not warp or dent, causing transport problems and preventing damage to the circuits in the circuit setting areas 32 during transport. Furthermore, in this embodiment, the top central cuboid 121 and the two top edge cuboids 122 still have drainage holes 18 to facilitate the removal of old chemicals and replacement with fresh chemicals during transport in the circuit manufacturing process, thus maintaining the cleanliness of the circuit setting areas 32.

[0101] Please see Figure 10 and Figure 11As shown, in the third embodiment of this utility model, the upper fixture unit 10 includes a plurality of top fixture members 19, and each top fixture member 19 is provided with a locking structure 11. The positions of the locking members 21 on the lower fixture unit 20, the positions of the through holes 34 on the substrate 30, and the positions of the locking structures 11 correspond to each other. In particular, in this embodiment, the positions of the through holes 34 on the substrate 30 are not only located in the invalid areas 33, but also at corresponding positions above and below the horizontal extension direction of the circuit setting areas 32. Thus, it means that the top fixture members 19 are correspondingly located at the positions of the invalid areas 33 above and below the horizontal extension direction of the circuit setting areas 32 on the substrate 30. When using a three-point roller system to transport the upper fixture unit 10, the lower fixture unit 20, and the substrate 30, the three rows of upper rollers 103 can avoid pressing down on the circuit arrangement areas 32 of the substrate 30 and the top fixture members 19 of the upper fixture unit 10. In other words, because the upper fixture unit 10 is composed of the top fixture members 19, and each of the top fixture members 19 is separate from each other, the top fixture members 19 do not have the same horizontal plane. Therefore, if an upper roller 103 presses down on a top fixture member 19, it may cause the upper roller 103 to jump. To avoid the aforementioned jumping situation when an upper roller 103 travels over a top fixture member 19, the top fixture members 19 are set off from the path traveled by the three rows of upper rollers 103, so that the three rows of upper rollers 103 can travel directly over the ineffective areas 33 of other parts of the substrate 30.

[0102] The top fixtures 19 of the upper fixture unit 10 still retain the function of connecting the lower fixture unit 20 and sufficiently stabilizing the substrate 30 between the upper fixture unit 10 and the lower fixture unit 20. Therefore, even if the ineffective areas 33 of the substrate 30 come into contact with the upper roller 103, the ineffective areas 33 are still supported by the lower fixture unit 20 below the substrate 30 and have sufficient rigidity, so they will not warp or dent and cause transmission problems, thereby avoiding damage to the circuits in the circuit setting areas 32 during transmission.

[0103] Please see Figure 12As shown, in the fourth embodiment of this utility model, the utility model further includes a plurality of clamps 40. In this embodiment, the upper jig unit 10 includes at least the aforementioned top central cuboid 121 and the two top edge cuboids 122. Preferably, the upper jig unit 10 may also include the aforementioned two top auxiliary cuboids 123. The clamps 40 clamp the top edge cuboids 122 of the upper jig unit 10 and the bottom edge cuboids 222 of the lower jig unit 20 together. Of course, the clamps 40 also clamp the substrate 30 located between the upper jig unit 10 and the lower jig unit 20. The clamps 40 are further configured with a track to create a frame-like transfer method for transferring the upper jig unit 10, the lower jig unit 20, and the substrate 30.

[0104] As described above, the lower jig unit 20 provides structural support for the ineffective areas 33 of the substrate 30, thus strengthening the overall rigidity of the substrate 30. This prevents the substrate 30 from bending or denting due to insufficient rigidity during transport on a horizontal plane. Therefore, this invention ensures that after the upper jig unit 10 and the lower jig unit 20 are combined, the substrate 30 can also be transported by using the clamps 40 to clamp the upper jig unit 10 and the lower jig unit 20, which are fixed between them. This invention ensures a smooth transport process, preventing the substrate 30 from being jammed or its circuitry areas 32 from being scratched or damaged during transport.

[0105] The above different embodiments are merely illustrations of several possible implementations of this utility model. Regardless of the embodiment, the lower fixture unit 20 of this utility model can be used to provide structural support for the substrate 30 between the upper fixture unit 10 and the lower fixture unit 20, thereby improving the rigidity of the substrate 30. Thus, when the substrate 30 needs to be transported, there is no need to use a horizontal transport method with dense rollers; instead, a horizontal transport method with three-point rollers or a clamp-type horizontal transport method can be used. This utility model can ensure that when the substrate 30 is transported using three-point rollers or a clamp-type method, regardless of whether the thickness of the substrate 30 is less than 0.4 mm or the thickness of the circuits in the circuit setting areas 32 of the substrate 30, the substrate 30 can be transported smoothly, thereby keeping the circuits on the substrate 30 intact and avoiding damage during the transport process.
