What is FPC?
FPC, flexible pcb printed circuit, which is a circuit board mainly composed of CU (Copperfoil), A (Adhesive) and PI (Kapton, Polyimide). It has manyadvantages such as space saving, weight reduction and high flexibility, whichhas a wide range of applications in production and life, and the market is stillexpanding.
FPC features
FPC application
FPCs are widely used in commercial electronic equipment, car dashboards, printers, hard drives, floppy drives, fax machines, mobile phones, general telephones, notebook computers, cameras, video cameras, CD-ROMs, Hard drives, watches, computers, cameras, medical equipment, and other electronic products and equipment.
