 FP1708E

Suitable use

 For small-to-medium-sized LCDs
/ For small-to-medium-sized organic EL panels

Application
  • AV/
  • Game machines/
  • Cellular phones/
  • Automobiles

Features
  • Our unique insulating coating technology on a conductive particle takes optimum conductivity in vertical while it completely insulates in horizontal. Suitable for the fine pitch connection.
  • A proprietary adhesive composition with excellent performance for bonding 2 layer FPCs.
  • Suitable for fine-pitched connections, e.g. of a driver IC on a flexible printed circuit board.

  • *1 Minimum space: Space between neighboring circuits.
  • *2 Minimum pitch: Total length of conductor width and space between neighboring circuits.
  • *3 Minimum connection area: A contact area which needs to trap at least three particles (average -4.5δ) and where the faced conductor overlaps.
  • *4 Temperature of ACF lamination and main bonding: It is not equipment temperature, but temperature of ACF.
  • *5 Time of ACF lamination and main bonding: Time from the start of bonding to the point where the temperature reaches the target.
  • *6 Pressure of ACF lamination: It is described as the area of ACF lamination.
  • *7 Pressure of main bonding: The pressure at COG mounting is described as the total area of bumps. The pressure at FOG, FOB, and FOF mounting is described as the bonding area.

Application Example
