  • Publication number: 20190355655
    Abstract: A semiconductor-mounted product includes a semiconductor package, a wiring substrate, four or more soldered portions, and a resin-reinforced portion. Each of the soldered portions electrically connects the semiconductor package to the wiring of the wiring substrate. The resin-reinforced portion is formed on a side surface of each of the soldered portions. Each of the soldered portions has a first solder region formed closer to the semiconductor package than the wiring substrate and a second solder region formed closer to the wiring substrate than the semiconductor package. A proportion of a void present in a polygon connecting centers of soldered portions located at outermost positions among the soldered portions to a sum of the void and the resin-reinforced portion is from 10% to 99%, inclusive.
