Abstract:
A method of producing a resin molding, comprising the steps of:(a) kneading a low melting point alloy with a thermoplastic or thermosetting base resin and a dispersing aid which includes at least one chemical element of said low melting point alloy to form a resin mixture, the low melting point alloy having a melting point lower than a molding temperature of said base resin;(b) forming a conductive material from the resin mixture;(c) molding a thermoplastic or thermosetting resin into a body through primary molding; and(d) integrating the resulting body with conductive parts of the conductive material through secondary moldingwherein the low melting point alloy consists essentially of tin, is free of lead and is in a melt or semi-melt during the secondary molding.
