Patent ID: 7967943

Claim:
A method for connecting circuit electrodes to form an electronic circuit comprising the steps of: (a) disposing a first electrode of a first circuit member to face a second electrode of a second circuit member; (b) interposing a circuit-connecting material between the facing electrodes, wherein the circuit-connecting material comprises: (1) a curing agent capable of generating free radicals upon heating, wherein the curing agent has a 10-hour half-life temperature of 40° C. or above and a 1-minute half-life temperature of 180° C. or below, and the curing agent comprises peroxyesters; (2) a radical-polymerizable substance; and (3) a hydroxyl-group-containing resin having a weight average molecular weight of 10,000 or more, wherein the hydroxyl-group-containing resin is at least one of polyvinyl butyral, polyvinyl formal, polyamide polyester, phenol resin, epoxy resin and phenoxy resin; and (c) curing the circuit-connecting material by heating and pressing the circuit-connecting material thereby electrically connecting the electrodes, either by direct contact or via conductive particles present in the material.
