Abstract: In connecting an electronic circuit part such as a semiconductor or other part to a substrate for mounting the part with solder, the solder is composed of a high-melting-point solder portion which is subjected to working such as rolling and heat treatment in order to break the cast structure thereof, and a smaller volume of low-melting-point solder portions. The high-melting-point solder portion is connected to both the electronic circuit substrate and the electronic circuit part through the low-point-melting solder portions.This method enables interconnection between objects to be connected without impairing the high ductility and toughness of the high-melting-point solder which is subjected to working and heat treatment. This soldering method ensures highly reliable manufacture of miniaturized high density circuits, such as LSI.
