8-layer soft-hard combination circuit board (through-hole board)

The soft-hard circuit board is made of soft board material polyimide (PI) and hard board materialsFR4Made by pressing together, it is a special combination of soft board and hard board.PCBCircuit boards are very flexible. The parts that need to be bent are designed as soft boards, and the parts that do not need to be bent are designed as hard boards, which can be flexibly adapted to the structural design of the product. Soft-hard circuit boards are widely used in automobiles, medical, Home appliances and other fields.
