Abstract:
1. An anisotropic conductive adhesive comprising an insulating adhesive component and a number of conductive particles, dispersed in the insulating adhesive component, wherein the insulating adhesive component contains a crosslinked rubber resin, a radical polymerizable resin, and a polymerization initiator, as well as at least one additive selected from the group consisting of i) a filler, ii) a softening agent, iii) an accelerator, iv) a staining agent, v) a flame retardant, vi) a light stabilizer, vii) a coupling agent selected from the group consisting of viii) a polymerization-inhibiting agent; wherein the crosslinked rubber resin is at least one selected from the group consisting of olefin resin, butadiene resin, acrylonitrile butadiene copolymer, styrene butadiene styrene copolymer, isobutylene isoprene copolymer(IIR), nitrile butadiene rubber resin, chloroprene rubber resin, vinyl butylal resin, silicon rubber resin and a mixture thereof; wherein the radical polymerizable resin is a monomer, an oligomer or both thereof, which is a material having radical group, polymerizable by radical; and wherein the polymerization initiator is a thermal polymerization initiator such as a carbonyl compound, a sulfur compound, and an azo compound.
