The best advantage of FPCB (Flexible Printed Circuit Board) is flexibility as its name has it. Therefore, density of wiring can be enhanced as these products allow for stand-alone three-dimensional wiring.
FPCB has become a must component as the electronic industry pursues multifunctional, compact and light devices.
YF-C/FCCL, These products, coated with polyimide films first and then with heat and fire resistant e-proxy adhesives, are suitable for fine patterns.
YF-L/Coverlay, These products, coated with polyimide films first and then with heat and fire resistant e-proxy adhesives, are used to protect and insulate surfaces of FCCL circuit boards as they offer excellent dimensional stability, heat resistance and adhesion.
YF-Stiffener, These products, coated with heat and fire resistant adhesives on polyimide films, offer excellent adhesion and little property changes even when stored for an extended period of time.
