Patent ID: 6878435

Claim:
A triple layered anisotropic conductive adhesive (ACA) film comprising: an epoxy resin-containing main ACA film containing conductive particles having a particle size of 3 to 10 μm and non-conductive particles having a particle size of 0.1 to 1 μm; and epoxy resin-containing adhesion reinforcing layers formed at both sides of the epoxy resin-containing main ACA film, wherein the main ACA film is formed by mixing and drying solid epoxy resin, liquid epoxy resin, solid phenoxy resin, solvent in which methylethylketone and toluene are mixed with each other, and liquid imidazole hardener, wherein the conductive particles have a concentration of 5 to 20% by weight with respect to the overall weight excluding the weight of the solvent.
