1. Different raw materials: FPC (Flexible Printing)
Circuit is a circuit board made of flexible materials (such as polyimide film, polyester film, etc.). ), generally used to connect high-density circuits; And PCB (printed circuit)
Board) is a circuit board made of hard materials, which is mostly used in general circuits.
2.
Different composition and structure: FPC is generally composed of conductive insulating film and adhesive layer, which can be bent, folded and swung freely when used; PCB is mostly composed of substrate, copper foil and ink. Do not bend or fold when using.
3.
The production process is different: FPC adopts repeated molding process, which does not need traditional PCB processing technology such as drilling, so it can achieve higher process accuracy and reliability; However, the production process of PCB is relatively complex, with a long single process cycle and relatively high cost.
4.
Different application fields: FPC is widely used in electronic products (such as connecting or blocking components in precision mechanical equipment such as mobile devices and light-emitting diodes) because of its soft and flexible performance, while PCB is widely used in consumer electronics, communications, automobiles, medical care, military industry and other industries.
In practical application, FPC or PCB should be selected according to actual needs to achieve better performance and effect.
