PCB board materials can be divided into: paper substrate, glass fiber cloth substrate, composite substrate (CEM series), laminated multilayer board substrate and special material substrate (ceramic, metal core substrate, etc.)
1. PCB, the Chinese name is printed circuit board, also known as printed circuit board,control pcb board ， is an important supporting component of electronic components and the carrier of electrical connection of electronic components.
2. The main material of printed circuit board (PCB) is copper clad laminate, and copper clad laminate (copper sheet) consists of substrate, copper foil and adhesive.
3. The base plate is an insulating layer board composed of polymer synthetic resin and reinforcing materials; the surface of the base material is covered with a layer of pure copper foil with high conductivity and good weldability, and the common thickness is 35~50/ma.
