Product Description

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.

99.9% Purity Red Rolled Electrodeposited Copper Foil

99.9% Purity Red Rolled Electrodeposited Copper Foil Description: Electrolytic copper foil is a foil-based form of copper with a thickness generally less than 80micron. A rolled foil is made by annealing and rolling the electrolytic copper uninterruptedly.The production process involves electrodepositing copper to a rolling drum and then again rolling it up. For the process of electrodeposition, high-grade copper is dissolved in acid to form a copper electrolyte. This copper
