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
- Reduce the size of the application product, save space, greatly reduce the weight, increase the effect, and reduce the cost.
- It has high flexibility and can be 3D wired, changing shape according to space constraints.
- Foldable without affecting signal transmission, anti-static interference.
- High temperature resistance and flame resistance.
- The chemical change is stable, and the stability and reliability are high.
- Provide more related solutions for related products, which can reduce assembly man-hours and errors, and improve the service life of related products.
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.
