ABSTRACT:
A lead-free solder powder that can include a plurality of lead-free solder particles each having a general spherical shape with a diameter of 20–60 μm. Each of the lead-free solder particles can contain Sn, Ag and Bi, with respective concentrations set such that the lead-free solder alloy has a melting temperature lower than a predetermined heat-resistant temperature of a work to be soldered.
