ANISOTROPIC CONDUCTIVE ADHESIVE FILM

摘要

PROBLEM TO BE SOLVED: To provide an anisotropic conductive adhesive film capable of reducing internal stress in thermo-compression bonding. SOLUTION: An anisotropic conductive adhesive film 1 is formed by dispersing conductive particles 7 in insulative adhesive resin 6. A difference between the linear expansion coefficient of the insulative adhesive resin 6 and the linear expansion coefficient of a coated object having a less linear expansion coefficient is not more than 35×10-6.K-1. In the insulative adhesive resin 6 20-70 wt.% of inorganic particles 9 are mixed. In the insulative adhesive resin 6 1-20 wt.% of elastic rubber particles 8 are dispersed.
