factory customized Copper Foil Roll - High-precision RA Copper Foil – CIVEN Detail:

Product Introduction

High-precision rolled copper foil is a high-quality material produced by CIVEN METAL. Compared to ordinary copper foil products, it has higher purity, better surface finish, better flatness, more precise tolerances and more perfect processing properties. The high precision copper foil has been also degrease and anti-oxidized, which allows the foil to have longer shelf life and be easier to laminate with other materials. As the material is manufactured and packaged in dust free room, the cleanliness of the product is very high and it meets the requirements of a high-end electronics production environment. All of our high precision rolled copper foil products are controlled and monitored according to the strictest international production standards, with the aim of achieving none defect. It can not just be the substitute of the same grade products from Japan and Western Countries, but also shorter the manufacturing period for our customers.

Copper foil is an indispensable raw material for making printed circuit board (PCB), copper clad laminate (CCL) and lithium-ion battery. Industrial copper foil can be divided into calendered copper foil and electrolytic copper foil according to its manufacturing process. Electrolytic copper foil is made by copper electrolysis based on electrochemical principle. The internal structure of the green foil is vertical needle crystal structure, and its production cost is relatively low. Calendered copper foil is formed by repeated rolling annealing process of copper ingot based on the principle of plastic processing. Its internal structure is flake crystalline structure, and the ductility of calendered copper foil products is good. At present, electrolytic copper foil is mainly used in the production of rigid circuit boards, while calendered copper foil is mainly used in flexible and high-frequency circuit boards.
