Abstract:
A method of providing an electrical interconnection comprising the steps of:a) applying a heat-curable electrically conductive adhesive film to an electrically conductive substrate, said adhesive film comprising an acrylate polymer, a polyepoxide resin, an effective amount of a heat-activatable modified aliphatic amine polyepoxide resin curing agent, said amine curing agent being insoluble in said adhesive film at 20.degree. C., and an effective amount of an electrically conductive material, said acrylate polymer comprising the polymerization reaction product of:i) an acrylate monomer; andii) a crosslinking agent having an acrylate moiety, wherein said composition and components (i) and (ii) are substantially solvent free; andb) curing said polyepoxide resin in said adhesive film by heating said adhesive film to a temperature of between 90 to 180.degree. C. for from 15 seconds to 5 minutes.
