Abstract
Description
Technical Field
[0001] The present application belongs to the field of semiconductor integrated circuits, and in particular relates to a circuit board fixture assembly. Background Art
[0002] Glue dispensing is required during the production process of circuit boards (also known as PCBs). Conventionally, the boards are placed on a flat surface for dispensing. Glue with good fluidity tends to overflow beyond the dispensing area, requiring additional process steps to remove the excess glue. Glue with poor fluidity cannot cover the dispensing area, resulting in a small bonding area with the board, reducing the board's durability and safety.
[0003] Utility Model
[0004] One of the purposes of this application is to provide a circuit board clamp assembly that can adapt to glues with different fluidities to increase the durability and safety of the circuit board.
[0005] To achieve the above-mentioned purpose and other related purposes, the present application provides a circuit board clamp assembly, including a fixed part, a rotating part, a guide part and a limiting part, wherein the fixed part is hinged to the rotating part and the guide part respectively; the rotating part is used to support the circuit board, and the side of the rotating part away from the hinged part to the fixed part can slide along the guide part; the guide part is provided with a fastener, and the fastener is used to fix one side of the rotating part sliding along the guide part so that the rotating part can be tilted at a predetermined angle relative to the fixed part; the limiting part is arranged on the upper surface of the rotating part, and is used for supporting the circuit board when the rotating part is tilted relative to the fixed part so that the circuit board does not fall off the rotating part.
[0006] This application has at least the following beneficial effects:
[0007] With the circuit board clamp assembly of the present application, the rotating portion can be tilted relative to the fixed portion at a predetermined angle, which is adapted to the fluidity of the glue. When using glue with poor fluidity, the predetermined angle is large, while when using glue with poor fluidity, the predetermined angle is small. This allows glues of varying fluidity to be evenly applied to the dispensing locations along the circuit board, while also increasing the bonding area between the glue and the circuit board, improving the durability and safety of the circuit board.

The fixed part 100 is hinged to the rotating part 200 and the guiding part 300 respectively. The rotating part 200 is used to carry the circuit board, and the side of the rotating part 200 away from the hinged part of the fixed part 100 can slide along the guiding part 300; the guiding part 300 is provided with a fastener, which is used to fix the side of the rotating part 200 sliding along the guiding part 300 so that the rotating part 200 can be tilted at a predetermined angle relative to the fixed part 100; the limiting part is provided on the upper surface of the rotating part 200, and is used to support the circuit board when the rotating part 200 is tilted relative to the fixed part 100, so that the circuit board does not fall off the rotating part 200.
[0015] With the circuit board clamp assembly of the present application, the rotating portion 200 can be tilted relative to the fixed portion 100 at a predetermined angle, which is adapted to the fluidity of the glue. When using glue with poor fluidity, the predetermined angle is large, while when using glue with poor fluidity, the predetermined angle is small.
