A DOUBLE LAYERED ANISTROPIC CONDUCTIVE FILM

摘要

PURPOSE: A bi-layered anisotropic conductive film is provided to release pressure disproportion at mounting, to reduce short fault generation, and to improve connection reliability by reducing connection resistance. CONSTITUTION: A bi-layered anisotropic conductive film comprises an epoxy resin comprising a polycyclic aromatic ring, and has minimum melt viscosity 3,000-10,000 Pa.s at 30-200°C. The comprised amount of the epoxy resin comprising the polycyclic aromatic ring is 20-60 weight% of the film. The bi-layered anisotropic conductive film comprises an anisotropic conductive film layer, and a non-conductive film layer. The glass transition temperature of the epoxy resin comprising the polycyclic aromatic ring is 165-250°C.
