ABSTRACT:
A water soluble solder flux particularly suitable for use as a fusing fluid in condensation soldering operations has been developed. The invention involves the use of such flux in condensation soldering as well as the flux, per se. The novel flux comprises a water soluble flux vehicle comprising a resinated polyethylene oxide (polyene), together with at least one flux activator selected from a water soluble organic acid activator and a water soluble halide containing activator, and a solvent which is water soluble.
