CNT Single-Side Thermocompression Bonding Polyimide Film
Specification
CNT Thermocompression bonding polyimide film is made up of CN coating CBDF, under certain temperatures and pressure, one side will produce viscosity due coating CBDF. Not only has the characteristics of polyimide film, but it also has more excellent performances in bonding strength.
Features:
Single adhesive, environment-friendly with halogen-free, highest UL-94 flammability rating: V-0.
