Abstract:
A method of manufacturing an electronic component having a pest repelling layer for repelling pest insects from the surface of a printed wiring board,(a) preparing an electronic component material having a pest repellent and a resin which may be crosslinked and cured, (b) applying said electronic component material at a specified position on the surface of said printed wiring board, (c) forming said cured pest repelling layer, containing said pest repellent, by crosslinking chemical reaction of said resin in said electronic component material on said printed wiring board, said pest repellent having a pyrolysis temperature of greater than about 250Â° C., wherein said electronic component material is a prepreg containing said resin and said pest repellent impregnated in a glass woven fabric or in a glass non-woven fabric, and curing the resin by heating and pressing, and when said resin is cured, said pest repelling layer is formed in a state in which part of said pest repellent is moved to the surface of said pest repelling layer by the action of a reactive diluent.
