The names of circuit boards are: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum substrate, high frequency board, thick copper board, impedance board, PCB, ultra-thin circuit board, ultra-thin circuit board Thin circuit boards, printed (copper etching technology) circuit boards, etc. The circuit board makes the circuit miniaturized and intuitive, and plays an important role in the mass production of fixed circuits and the optimization of the layout of electrical appliances. The circuit board can be called a printed circuit board or a printed circuit board, the English name is (Printed Circuit Board) PCB, (Flexible Printed Circuit board) FPC circuit board (FPC circuit board, also known as flexible circuit board Flexible circuit board is based on polyimide Or polyester film as the base material is a highly reliable, excellent flexible printed circuit board. It has the characteristics of high wiring density, light weight, thin thickness and good bending.) and soft and hard Combination board (reechas, Soft and hard combination plate) - The birth and development of FPC and PCB gave birth to the new product of soft and hard combination plate. Therefore, the soft-rigid board is a circuit board with FPC characteristics and PCB characteristics formed by combining flexible circuit boards and rigid circuit boards according to relevant process requirements through lamination and other processes.
