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 substrate. With both excellent conductivity and insulating property between terminals for fine pitch interconnection.

  • Product name
    CP540 series
  • Features
    • Excellent conductivity and insulating performance between terminals by insulation coated particles
    • A large number of bumps with fine pitch can be bonded at one time by an optimum thermal compression.
    • The warpage of the IC chip was decreased by low temperature bonding from 130°C to 160°C.
    • 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 connective reliability
