Factory source Copper Strips - RTF ED Copper Foil – CIVEN
Product Introduction Reverse treated electrolytic copper foil (RTF) is a copper foil that has been roughened to varying degrees on both sides. This strengthens the peel strength of both sides of the copper foil, making it easier to use as an intermediate layer for bonding to other materials. Moreover, the different levels of treatment on both sides of the copper foil make it easier to etch the thinner side of the roughened layer. In the process of making a printed circuit board (PCB) pan... -

Manufacturer of Bcf Copper Foil - ED Copper Foils for FPC – CIVEN
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 ... -
Special Price for Double Mat Copper Foil - Treated RA Copper Foil – CIVEN
Product Introduction Treated RA copper foil is a single side roughened high precision copper foil in order to increase its peel strength. The roughened surface of copper foil likes a frosted texture, which makes it easier to laminate with other materials and less likely to peel off. There are two mainstream treatment methods: one is called reddening treatment, where the main ingredient is copper powder and the surface color is red after treatment; the other is blackening treatment, where... -
