Description

Technical Field

[0001] This utility model relates to a protective cover, specifically a protective cover for test board components. Background Technology

[0002] Because there are components on the surface of the test board, these components are easily scratched off during the testing process, especially the 93K test board.

[0003] Therefore, it is necessary to provide a protective cover for the test board components. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a protective cover for test board components.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A protective cover for test board components includes a first cover and a second cover.

[0007] The first cover plate is provided with a plurality of first through holes, the first through holes corresponding to the component and socket mounting areas on the test board surface;

[0008] The second cover plate is provided with a plurality of second through holes, the second through holes corresponding to the socket mounting area;

[0009] The first cover plate is used to cover the test plate.

[0010] The second cover plate is used for the first cover plate.

[0011] The first and second cover plates mentioned above are made of ESD material, which includes PTFE, ZnO, SiO2, and acrylic resin.

[0012] The thickness of the first cover plate is no more than 2 mm.

[0013] The thickness of the second cover plate is no more than 2 mm.

[0014] Both the first and second cover plates mentioned above are transparent.

[0015] The first cover plate and the second cover plate are provided with positioning grooves on at least one side edge.

[0016] The advantages of this utility model are:

[0017] This utility model discloses a protective cover for test board components. By setting two stackable cover plates, the first cover plate has a through hole at the corresponding component location, and a corresponding through hole is set in the corresponding socket mounting area. By stacking, the components are completely covered, leaving only the socket mounting area exposed. This effectively protects the components on the test board from being scratched and dropped, improving the efficiency and safety of chip mass production testing. Its structure is simple, convenient to use, and has strong practicality and wide applicability. Attached Figure Description

[0018] Figure 1 This is a diagram of the first cover plate.

[0019] Figure 2 This is a diagram of the second cover plate.

[0020] Figure 3 This is a diagram showing the first and second cover plates in their closed state. Detailed Implementation

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] A protective cover for test board components, comprising a first cover and a second cover.

[0023] The first cover plate and the second cover plate are each provided with a number of through holes; wherein, the through holes on the first cover plate are first through holes corresponding to the component and socket mounting areas on the test board surface; the through holes on the second cover plate are second through holes corresponding to the socket mounting areas on the test board.

[0024] Because the protective cover will come into contact with the components on the test board, the material of the protective cover must be ESD-resistant to avoid ESD problems. Preferably, the first and second covers can be made of materials such as PTFE, ZnO, SiO2, or acrylic resin.

[0025] Preferably, the thickness of the first cover plate and the second cover plate is ≤2mm, and the combined thickness is ≤4mm.

[0026] When using,

[0027] The first cover plate covers the test board, and the cutout part (first through hole) corresponds to the component and socket mounting area.

[0028] The second cover plate covers the first cover plate, and the hollow part (second through hole) corresponds to the opcket mounting area.

[0029] To facilitate positioning and fixing, positioning grooves can be provided on at least one side edge of the first and second cover plates. To facilitate observation of components, both the first and second cover plates can be made into transparent plates.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that the above embodiments do not limit this utility model in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this utility model.
