Abstract:
1. A method for manufacturing a mounted body, the method comprising the steps of: (a) placing, on a mounting board on which a wiring pattern having an electrode terminal is formed, a semiconductor element having a surface on which an element electrode is formed and a rear surface opposing said surface such that the rear surface of the semiconductor element faces the mounting board; (b) applying a solder resin paste, obtained by mixing in a resin a solder powder and a convection additive that boils when the resin is heated, to a region including the element electrode and the electrode terminal; (c) arranging a substrate having a first surface on which an electrode pattern is formed and a second surface opposing the first surface such that the first surface of the substrate faces the surface of the semiconductor element and the mounting board with the solder resin paste intervening therebetween and that the electrode pattern of the substrate covers the element electrode and the electrode terminal; and (d) heating the solder resin paste so that the convection additive boils to cause convection in the resin, thus causing self-assembly of the solder powder contained in the solder resin paste to form a solder member that connects at least between the element electrode and the electrode pattern and between the electrode terminal and the electrode pattern.
