CNTC Double-Side Thermocompression Bonding Polyimide Film
Specification
CNTC Double-Side Thermocompression bonding polyimide film is made up of CN coating CBDF on both side, under certain temperature and pressure, the double side will produce viscosity. Double-Side PI film has the characteristics of polyimide film but also has more excellent performances in bonding strength.
CNTC double-side polyimide film is the excellent heating-resistant material with the characteristics of high insulation, chemical stability, radiation resistance, self-extinguishing and so on. It has the highest UL-94 flammability rating: V-0 and environment-friendly with halogen-free.
