RA Copper Foils for FPC

Product Introduction

Copper foil for circuit boards is a copper foil product developed and produced by CIVEN METAL specifically for the PCB/FPC industry. This rolled copper foil has high strength, flexibility, ductility and surface finish, and its thermal and electrical conductivity is better than similar products. The requirements for copper foil materials in circuit board production are very high, especially for high-end flexible circuit board (FPC) manufacturing. We have developed copper foil for a wide range of PCB manufacturing industries to meet the needs of our customers for high-end PCB manufacturing materials. At the same time, CIVEN METAL can also customize production according to different product requirements of customers. It’s a good optional way to change relying on the products from Japan or Western Countries.

Flexible circuit board is flexible, which gets rid of the limitations of conventional circuit plane design, and can arrange lines in three-dimensional space. Its circuit is more flexible and has higher technical content. Calendered copper foil has become the best choice for manufacturing flexible printed circuit board because of its flexibility and bending resistance.

It is widely used in flexible copper clad laminate (FCCL), flexible circuit board (FPC), 5g communication FPC, 6G communication FPC, electromagnetic shield, heat dissipation substrate, graphene film preparation base material, aerospace FPC / electromagnetic shield / heat dissipation substrate, lithium battery (using calendered copper foil as negative material), LED (using calendered copper foil as FPC), intelligent automobile FPC, UAV FPC FPC for wearable electronic products and other industries
