Easy-to-assemble large-current composite circuit board and manufacturing process therefor

Abstract

Disclosed is an easy-to-assemble large-current composite circuit board and a manufacturing process therefor. The easy-to-assemble large-current composite circuit board comprises a base plate assembly (100). The base plate assembly (100) consists of an outer shell (110), an insulating board (120), a composite circuit board (130) and an insulating packaging layer (140) in turn from top to bottom. The composite circuit board (130) is provided with insulating grooves (134) and mounting holes (135) for conducting electricity. Through holes (150) corresponding to the positions of the mounting holes (135) are formed in the outer shell (110) and the insulating board (120). The composite circuit board (130) of the invention has a simple structure. The base plate assembly (100) based on the manufacturing process of the composite circuit board (130) has a better load-bearing effect, and the conductive posts (200) are riveted to the composite circuit board (130) by means of a riveting technique, and then the connecting wires (400) are fixed to the upper ends (210) of the conductive posts (200) by means of conductive screws, so that the components (300) and the composite circuit board (130) are electrically connected. Due to this structure, the assembly process can be simplified, and the assembly efficiency can be improved. Moreover, the test can be carried out as soon as the conductive posts (200) are riveted. In this way, the problem that the defects of the base plate assembly (100) can be discovered only after the components (300) are assembled can be avoided effectively, thereby reducing the generation of defective products and the rework and maintenance rate, ensuring the pass rate of finished products, and reducing the production cost of enterprises.
