Product Introduction

Electrolytic copper foil for FPC is specially developed and manufactured for the FPC industry (FCCL). This electrolytic copper foil has better ductility, lower roughness and better peel strength than other copper foils. At the same time, the surface finish and fineness of the copper foil is better and the folding resistance is also better than similar copper foil products. Since this copper foil is based on the electrolytic process, it does not contain grease, which makes it easier to be combined with TPI materials at high temperatures.
