The name of the circuit board is: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum plate, high frequency board, thick copper plate, impedance board, PCB, ultra-thin circuit board Thin circuit boards, printing (copper etching technology) circuit boards and so on. The circuit board makes the circuit miniaturized and intuitive, which plays an important role in the mass production and optimization of the fixed circuit. Circuit board can be called printed circuit board or
printed circuit board, the English name (Printed Circuit Board) PCB, (Flexible Printed Circuit board) FPC circuit board  (FPC circuit board, also known as flexible circuit board flexible circuit board is poly Imide or polyester film made of a substrate with a high degree of reliability, excellent flexible printed circuit board with a high wiring density, light weight, thin thickness, good bending characteristics!) And soft and hard combination plate (reechas, Soft and hard combination plate) -FPC and PCB birth and development, gave birth to a soft and hard combination of this new product. Therefore, the hard and soft bonding board, that is, flexible circuit boards and rigid circuit boards, after pressing and other processes, according to the relevant process requirements together to form a FPC characteristics and PCB characteristics of the circuit board.
