ABSTRACT:
Water soluble fluxing bath compositions have particular value in immersion soldering of metallic surfaces and electrical connections in that they are characterized by good thermal and chemical stability and easy removal of flux residues without corrosion or insulation resistance hazards. The compositions comprise from about 2 to 8 percent by weight of chelating agents or salts dissolved in a solvent, such as glycerol. In some instances from about 0.1 to 1.0 percent of an inorganic acid, such as hydrochloric acid may be added.
