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