摘要：
A flip chip mounting body in which a circuit substrate having a plurality of connection terminals and an electronic part (semiconductor chip) having a plurality of electrode terminals are aligned face to face with each other, with a resin composition composed of solder powder, a resin and a convection additive being sandwiched in between, while a means such as spacers is interposed in between so as to provide a uniform gap between the two parts, or the electronic part (semiconductor chip) is placed inside a plate-shaped member having two or more protruding portions, so that the solder powder is allowed to move through boiling of the convection additive and to be self-aggregated to form a solder layer, thereby electrically connecting the connection terminals and the electrode terminals; and a mounting method for such a mounting body.
