Conductive Flexible Film

Conductive flexible film is developed by copper having low resistance sputtered on the insulator film (PET).
Fine line patterning and designing according to electrical properties have been realized with microfabrication technologies developed in the manufacturing of electronics products.
Applications such as film antenna, electromagnetic shield, and various types of sensors are expected.

Features

  • Low sheet resistance copper is sputtered on the insulator film (Double / Single side)
    → Reduced power loss, control of large size possible
  • Fine line patterns are formed with Toppan’s microfabrication technologies
  • Designing according to electrical properties possible
  • Combinations of copper film and PET are varied, wide range of applications possible
    → Different thickness combinations of copper film and PET
