CCL/PPG


Key material for IC package substrate for semiconductors
PPG is manufactured by impregnating glass fibers with resin and then hardening them, and plays the role of a bonding sheet in the stacking process of package substrate(connects semiconductors to PCB). CCL, a laminated Cu foil layer formed by coating both sides of PPG with copper, plays the role of an insulator. CCL and PPG are key materials of a semiconductor's IC package substrate. With their excellent electrical characteristics and reliability, they make possible miniaturization and thin-layer manufacturing of semiconductor devices.
