ANISOTROPIC CONDUCTIVE ADHESIVE COMPOSITION FOR HIGH OVERFLOW, PEEL STRENGTH AND THE ANISOTROPIC CONDUCTIVE FILM THEREOF

摘要

An anisotropic conductive adhesive composition, and an anisotropic conductive adhesive film formed by using the composition are provided to improve adhesive strength, heat resistance, humidity resistance, flowability and electrical conductive stability. An anisotropic conductive adhesive composition comprises 100 parts by weight of an ethylene-vinyl acetate copolymer; 10-100 parts by weight of a carboxyl-modified polyacetal resin having a molecular weight of 10,000 or more; 40-180 parts by weight of a radical polymerizable material; 0.3-10 parts by weight of a radical initiator based on 100 parts by weight of the copolymer, the polyacetal resin and the radical polymerizable material; and 0.2-30 parts by weight of a conductive particle based on 100 parts by weight of the radical polymerizable material and the polyacetal resin.
