Problems solved by technology

However, free radical curing is accompanied by a considerable shrinkage in volume and a decrease in molecular weight after curing, which makes it difficult for free radical curing materials to meet the needs of electronic materials
Therefore, despite the high curing rate, it is difficult for free radical curing materials to ensure high reliability circuit connection in a processing time of less than 10 seconds

Abstract

The present invention relates to an anisotropic conductive adhesive composition with high reliability and an anisotropic conductive film. The anisotropic conductive adhesive composition includes an acrylic rubber binder having a weight average molecular weight of about 100,000 to about 1,000,000, a first component including at least one of a mono(meth)acrylate compound and a di(meth)acrylate compound, a second component including at least one of a tri(meth)acrylate compound and a compound having more than three (meth)acrylate groups, an organic peroxisde, and conductive particles. The second component is present in an amount of about 1 to about 10% by weight, based on the total weight of the acrylic rubber, the first component, the second component, the organic peroxide, and the conductive particles.
