The name of circuit board includes: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum substrate, high-frequency board, thick copper plate, impedance board, PCB, ultra-thin circuit board, ultra-thin circuit board, printed (copper etching technology) circuit board, etc. The circuit board makes the circuit miniaturized and intuitive, and plays an important role in the batch production of fixed circuits and the optimization of the layout of electrical appliances. The circuit board can be called printed circuit board or printed circuit board, and the English name is (printed circuit board) PCB, (flexible printed circuit board) FPC circuit board (FPC circuit board is also called flexible circuit board. Flexible circuit board is a highly reliable and excellent flexible printed circuit board made of polyimide or polyester film. It has the characteristics of high wiring density, light weight, thin thickness and good bending property.) The birth and development of FPC and PCB have given birth to the new product of soft and hard combination plate. Therefore, the soft hard combination board is a circuit board with FPC characteristics and PCB characteristics formed by combining the flexible circuit board and the hard circuit board through pressing and other processes according to the relevant process requirements.
