Abstract

A solder precipitating composition comprises a powder of a metal having the highest ionization level among metals constituting a solder alloy to be prepared, and a salt between a carboxylic acid and a remaining metal of the solder alloy. The composition is applied to a surface on which the solder is to be precipitated, and the solder is precipitated, thereby performing soldering.
