CBF (Conductive Bonding Film)
JCF-1060 is thermosetting conductive bonding film developed by conductive adhesive compounding technology in conjunction with film manufacturing technology. Since adhesive layer of JCF-1060 is conductive, it can bond FPC which contains component assembly such as camera module or LCD module of cell phones to stiffener, and also provides EMI shielding function.
[Application]
• To adhere and electrically conduct FPC and metal stiffener
[Features]
• Outstanding adhesion to stiffener (Ni/SUS, Nickel silver)
• Strengthens GND by conducting GND pattern of FPC to metal stiffener with stable conductivity
• High tolerance to moisture and heat
