Abstract:
A method for connecting circuit boards comprising the steps of:providing composition of metal particles and a hydrocarbon compound having Câ€”H bonding dissociation energy of a value equal to or lower than 950 KJ/mol; applying said composition between a metal terminal of a first circuit board and a metal terminal of a second circuit board; and heating connection portions of both circuit boards to connect a metal terminal of the first circuit board and a metal terminal of the second circuit board with interposition of the composition therebetween, wherein the hydrocarbon compound is selected from a group consisting of cyclo-octane, tetramethyl-pentadecane, triphenylmethane, dicyclo-pentadiene, and dihydro-anthracene.
