FLEXIBILE PCB

摘要

The printed circuit board(PCB) includes a bonding layer between an insulating film and thin metal layer. The bonding layer is manufactured by coating the insulating film with a mixture consisting of (in wt.%) 10-60% epoxy resin, 20-45% polyamide resin, 10-50% phenol resin and 0.1-3% aromatic amine, and drying the coating. The PCB has excellent interlayer bonding strength, heat resistance and chemical resistance.
