Density: rolled copper foil higher density, the surface is relatively smooth, conducive to the production of printed circuit board after the rapid transmission of the signal, so high-frequency high-speed transmission, fine lines printed circuit board also used some calendering copper Foil.
Surface treatment width:rolled copper foil be limited by Surface treatment widest effective width of 520mm.

Application:

Chip on flex (COF) for LED
COVERLAY of FCCL
BONDING FILM of FCCL
STIFFENER of FCCL
Semi-flex CCL

Package:wooden carton
