Hyper Very Low Profile Copper Foil For High Speed Transmission Thickness 12um 18um 35um
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.
