High Purity RA Copper Foil With Good Mechanical Performance for
(1) Flexible Copper Clad Laminate(FCCL)
(2) Fine Circuit FPC
(3) LED coated crystal thin film.
(4) Adhesion Tape
(5) Anti - Peel devices and so on
(1) Thickness: 0.012mm / 0.018mm / 0.035mm
(2) Width: 260mm / 520mm and so on .
(1) High flexibility and extensibility
(2) Even and smooth surface
(3) Good fatigue resistance
(4) Strong antioxidant properties
(5) Good mechanical properties
(6) The material has higher extensibility
(7) It has a high bending resistance
(8) It has no crack.
- Rolled Copper Foil has extraordinary strength, bendability,
ductility and lustrous surface, plus its excellent mechanical
capacity, makes it irreplaceable as a raw material. Especially when
used for transformer, Copper Flexible Connector, CCL, FCCL, PCB,
Geothermal Film, Construction, Decoration etc.
- The copper foil made by Civen can be customized for different
temper, which including soft , quarter hard,half hard , hard
temper, even special soft and special hard temper.
- Soft temper are particularly strong demanded since it has wide
range of use. For transformer, it need soft cooper foil to avoid
high resistance and good heat radiating when it work.For copper
flexible connector , it prefer soft copper because it has good
extension and bendiablity. And for CCL,FCCLand PCB useage, the
copper they needed will depending on the surface roughness. But for
decorating and some other application, they need the copper to be
hard and then it will not be out of shape when after a period of
- RA copper foil’s special features make it irreplaceable for most of
electronic requirements acted as thermal conductive, electricity
conductive, EMI/EMC or some other functions.
