OEM/ODM Manufacturer Nickel Copper Foil - 3L Flexible Copper Clad Laminate – CIVEN
Product Introduction In addition to the advantages of thin, light and flexible, FCCL with polyimide based film also has excellent electrical properties, thermal properties, and heat resistance characteristics. Its low dielectric constant (DK) makes electrical signals transmit rapidly. Good thermal performance makes the components easy to cool down. The higher glass transition temperature (Tg) allows the components to operate well at higher temperatures. Since most of the products of FCCL are ... -
China Factory for Single 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... -
