Abstract:
A method of connecting a first wiring connector on a first circuit board and a second wiring connector on a second circuit board, comprising:disposing said first wiring connector on said first circuit board and said second wiring connector on said second circuit board, said first wiring connector disposed opposite said second wiring connector, said first wiring connector on said first circuit board composed of metal and said second wiring connector on said second circuit board composed of metal and having a hydrocarbon compound interposed therebetween, said hydrocarbon having a Câ€”H bond disassociation energy less than 950 kJ/mol; and decomposing said hydrocarbon compound to form a radical, said hydrocarbon being decomposed by separating hydrogen from said hydrocarbon compound by heating said hydrocarbon compound, said radical formed from said hydrocarbon compound and reducing oxide film on a surface of said metal of said first wiring connector and said second wiring connector while bonding the first wiring connector and second wiring connector on said first circuit board and said second circuit board respectively by fusion or diffusion, wherein the hydrocarbon compound is selected from a group consisting of binary alicyclic formula hydrocarbon, tertiary straight chain formula hydrocarbon, alicyclic formula hydrocarbon containing tertiary allyl position hydrogen, and alicyclic formula hydrocarbon containing binary benzylic position hydrogen both sides.
