Solder composition, connecting process with soldering, and connection structure with soldering

摘要

There is provided a solder composition which contains: (1) a metal material comprising solder particles, and (2) a thermosetting flux material comprising a thermosetting resin and a solid resin which changes to be in its liquid-like state when heated with a proviso that the thermosetting resin is excluded from the solid resin, wherein a temperature at which the solid resin changes to be in the liquid-like state is lower than a temperature at which the thermosetting resin starts to cure.
