Anisotropic Conductive Film (ACF)

Anisotropic Conductive Film (ACF) for Chip On Glass for small-to-medium-sized FPDs

Suitable for direct bonding of driver IC which drives a flat panel display onto glass substrate. With both excellent conductivity and insulating property between terminals for fine pitch interconnection.

  • Product name
    CP692 series
  • Features
    • Both optimum conductivity in vertical and complete insulation in horizontal are possible by our unique insulating coating technology on conductive particle.
    • A large number of bumps with fine pitch can be bonded at one time by an optimum thermal compression.
    • High reliability by excellent Anti-migration feature.
    • Efficient capturing performance of conductive particle and compatibility for fine-pitch application can be achieved by the 2 layer structure of ACF accommodates adhesive layer and non-conductive layer.
    • Excellent conductive reliability.
