Abstract:
A bonding method for electronically bonding a pad portion of a mounting substrate and a lead terminal of a functional element with an anisotropic conductive adhesive, said method consisting of the steps of:a) preparing a two pack adhesive of an A agent composed of an acrylic monomer, dimethylaniline, an epoxy resin precursor, solid imidazole and a microcapsule conductive tiller, and a B agent composed of benzoyl peroxide; b) adhering and fixing said mounting substrate and said functional element by applying the A agent and the B agent between the pad portion and the lead terminal at room temperature; and c) curing said epoxy resin precursor by action of the solid imidazole under a heat-curing condition of a temperature from 80 to 150Â° C.
