Anisotropic Conductive Film (ACF)

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

Suitable for interconnection of small-to-medium-sized FPDs and film materials.

  • Product name
    PAF700 series
  • Features
    • The particles arraying technique arrays conductive particles at the targeted positions and the particles immobilizing technique suppresses flow of them during the bonding provide stable particle capturing performance with a small number of particles.
    • Decreasing the number of conductive particles and immobilizing them reduces the risk of short-circuit for fine-pitch connections.
    • In interconnection of COF and a panel, it provides a minimum connection area of 1,000 µm2 and a minimum space of 5 µm.
    • 0.6 mm product width is available.
