Description：
CNTC Double-Side Thermocompression bonding polyimide film is made up by CEN® CN coating CBDF on both side, under certain temperature and pressure, double side will produce viscosity. It has the characteristics of polyimide film, but also has more excellent performances in bonding strength.
Features：
It 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.
Structure：
