PCB circuit board can be divided into rigid pcb circuit board and soft PCB circuit board according to the raw materials.
Rigid printed boards include phenolic paper laminated board, epoxy paper laminated board, polyester glass felt laminated board and epoxy glass cloth laminated board.
FPC is also called FPC. Flexible printed circuit board is a kind of printed circuit board made of polyimide or polyester film with high reliability and flexibility.
The circuit board has good heat dissipation performance, can be bent, folded, bent, and can move and expand in three-dimensional space. FPC can be used to reduce the volume, realize lightweight, miniaturization and thinness, so as to realize the integration of component device and wire connection.
FPC is widely used in electronic computers, communications, aerospace, household appliances and other manufacturing industries.
