Description

Technical Field

[0001] This utility model relates to the field of PCB boards, and in particular to a thin-plate auxiliary clamp. Background Technology

[0002] When PCB thin boards (generally defined as 0.1-0.5mm) undergo copper plating / VCP processes, equipment limitations can easily cause board jamming, resulting in board wrinkling, board damage and scrap, which seriously affects quality.

[0003] The next step was to use tape. While this method was feasible, it was time-consuming, wasteful of materials, and prone to leaving adhesive residue on the edges of the boards that could not be removed. Furthermore, the tape's adhesion was insufficient during processing, causing the boards to detach. This method affected production efficiency and was prone to quality problems. Utility Model Content

[0004] To address the aforementioned problems, this technical solution provides a thin-plate auxiliary fixture.

[0005] To achieve the above objectives, the technical solution is as follows:

[0006] A thin plate auxiliary fixture includes a fixture body, the fixture body having a recessed receiving cavity for accommodating a circuit board, and a limiting part for limiting the circuit board.

[0007] In some embodiments, the distance between the bottom of the accommodating cavity and the limiting portion is between 0.1 and 0.5 mm.

[0008] In some embodiments, the limiting part is provided with a through hole, and a positioning part is detachably connected inside the through hole.

[0009] In some embodiments, the positioning portion includes an insertion portion that can pass through the through hole and a stepped portion that contacts the limiting portion.

[0010] In some embodiments, the fixture body is a bare board etched from a PCB board.

[0011] The beneficial effects of this application are:

[0012] This application uses a fixture to hold a thin plate as it enters the production line for different processes. The limiting part limits the plate and achieves a stabilizing effect, which can effectively avoid problems such as plate jamming, plate breakage, and plate damage. Attached Figure Description

[0013] To more clearly illustrate the technical solutions in the embodiments of this utility model, the accompanying drawings used in the description of the embodiments will be briefly introduced below.

[0016] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] Please refer to Figure 1-2 As shown, a thin plate auxiliary fixture includes a fixture body 1, the fixture body 1 having a recessed receiving cavity 2 for accommodating a circuit board, and a limiting part 3 for limiting the circuit board.

[0018] This application provides a fixture that uses a 1.0mm thick waste PCB board etched into a bare board and then routerd into a rectangular strip the same length as the working piece. One end of the strip is routerd with a row of limiting parts. During processing, the left and right ends of the mother board are clamped by the limiting parts of this fixture to secure the board edges by 4mm as it passes through the production line without affecting the inside of the board. This fixture effectively stabilizes the board and avoids problems such as board jamming, board bending, and board damage. It is suitable for processes such as copper plating / VCP and outer layer etching stripping lines. This fixture can be reused for thin boards, solving the quality problems such as the need to use tape to attach the board each time and the residue left inside the board that cannot be removed. This achieves cost savings, time savings, improved efficiency, and stable quality.

[0019] In this embodiment, the distance between the bottom of the accommodating cavity 2 and the limiting part 3 is between 0.1 and 0.5 mm.

[0020] In this embodiment, the limiting part 3 is provided with a through hole 4, and a positioning part 5 is detachably connected inside the through hole 4.

[0021] Furthermore, the positioning part 5 includes an insertion part 51 that can pass through the through hole 4, and a stepped part 52 that contacts the limiting part 3. Passing the positioning part through the through hole can further press the edge of the plate.

[0022] In this embodiment, the fixture body 1 is a bare board etched from a PCB board.

[0023] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
