500mm RA Copper Foil
FPC RA Copper Foil
Description:
Made of pure copper, copper grade T2(China), C1100(Japan), C11000(USA), E-CU58(Germany), CU-ETP(EU, ISO). Copper purity more than 99.95%. This is RA copper foil, one side is polished side and the other side is matte. We also have ED copper foil, ED copper foil can choose one side polished and double side polished. The ED copper can have a higher purity. welcome to contact us if you need it.
Width, length, thickness all can be customized. we can also provide DIE cutting service.
We are also copper foil processing factory, Backing adhesive glue on the copper foil, laminate the copper foil with polymer films like PET, PI, PE and other films. DIE cut into customized shapes. you can send us your drawings and we can cut it into your shapes.
Size:
Thickness Range: ≥ 12 um (0.012mm or 0.0005 inch )
Width Range : 1 mm ~ 600 mm ( Up to 23.6 inch )
Features:
