Hyper Very Low Profile Copper Foil For High Speed Transmission
JIMA Copper proprietary ultra low roughness treatment process ensures effective adhesion strength for low Dk film materials, for which adhesion strength is difficult to achieve, without sacrificing transmission properties. Due to the recrystallized base foil, it also offers superior bending characteristics for contributing to the next generation of flexible printed circuits.
● Thickness: 12um 18um 35um
