Package Materials: S’PERFLEX Copper-clad Polyimide Films


Copper is laminated without an adhesive on the insulator film. - This is the most simply-composed material among flexible electronics materials.
Nevertheless, advanced metallizing technology is concentrated in this product, and the high quality characteristics that are required for LCD panel COFs are realized.

  • Fine patterning: A thin and even copper layer is optimal for high-precision processing.
  • High reliability: High adhesion and excellent electrical isolation are realized.
  • High durability against bending: High durability is realized through our unique plating technology.
