professional factory for Conductive Copper Tape - HTE Electrodeposited Copper Foils for PCB – CIVEN Detail:

Product Introduction

The electrolytic copper foil produced by CIVEN METAL has excellent resistance to high temperatures and high ductility. The copper foil does not oxidize or change color at high temperatures, and its good ductility makes it easy to laminate with other materials. The copper foil produced by the electrolysis process has a very clean surface and a flat sheet shape. The copper foil itself is roughened on one side, which makes it easier to adhere to other materials. The overall purity of the copper foil is very high, and it has excellent electrical and thermal conductivity. In order to meet the needs of our customers, we can provide not only rolls of copper foil, but also customized slicing services.
