FPC, flexible pcb printed circuit, which is a circuit board mainly composed of CU (Copperfoil), A(Adhesive) and PI (Kapton, Polyimide). It has many advantages such as space saving, weight reduction and high flexibility, which has a wide range of applications in production and life, and the market is still expanding.

Cu copper layer, there are RA (Rolled Annealed Copper) and ED (Electrodeposited)
ED copper is inexpensive to manufacture but fragile, and the copper body is easily broken when bend or driver.
RA copper is expensive to manufacture but flexible, so FPC copper foil is mainly RA copper.
Acrylic and epoxy thermosetting adhesive.
PI is Polyimide, which is called Kapton in DuPont, the thickness unit is 1/1000 inch lmil. It is thin with high temperature resistance, strong resistance to chemicals, and good electrical insulation.
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.
