ABSTRACT:
Disclosed is a triple layered ACA film adapted for enhancing the adhesion strength of a typical single layer Anisotropic Conductive Film or for enhancing the adhesion strength of the ACA film in flip chip bonding. The triple layered ACA film of the invention comprises: a main ACA film based upon epoxy resin and containing conductive particles having a particle size of 3 to 10 μm and optionally non-conductive particles having a particle size of 0.1 to 1 μm; and adhesion reinforcing layers based upon epoxy resin and formed at both sides of the main ACA film.
