T2 Conductive High Temperature Copper Foil Sheet Roll
Product Profile :
We developed out there treated copper foil that has very low profile, this kind of copper foil is best for high frequency application.The surface treated copper foil, like 18um, 35um, 50um usually used in Multi-layer and double face FPCB construction, We also produce heavy ED copper foil, mainly for high current FPCB construction.
