According to the CAD file of the circuit board, read the hole positioning data of FPC to manufacture high-precision FPC positioning template and special carrier plate, so that the diameter of the positioning pin on the positioning template matches the diameter of the positioning hole on the carrier plate and the positioning hole on the FPC. Many FPCs are not of the same thickness because of the need to protect some lines or design reasons. Some parts are thick, some parts are thin, and some have reinforced metal plates. Therefore, the joint between the carrier plate and FPC needs to be processed, polished and grooved according to the actual situation to ensure that the FPC is flat during printing and mounting. The material of carrier plate shall be thin, high strength, less heat absorption, fast heat dissipation, and small warpage deformation after multiple thermal shocks. Commonly used carrier plate materials include synthetic stone, aluminum plate, silica gel plate, special high temperature resistant magnetized steel plate, etc.
