Solder particles and method for producing solder particles

Abstract

A method for producing solder particles, which includes: a preparation step wherein a base material that has a plurality of recesses and solder fine particles are prepared; an accommodation step wherein at least some of the solder fine particles are accommodated in the recesses; and a fusing step wherein the solder fine particles accommodated in the recesses are fused, thereby forming solder particles within the recesses. With respect to this method for producing solder particles, the average particle diameter of the solder particles is from 1 μm to 30 μm; and the C.V. value of the solder particles is 20% or less.
