ABSTRACT:
A rosin free, water soluble solder flux suitable for use as a fusing fluid in high temperature solder operations has been developed. The novel flux comprises a high molecular weight amine activator, at least one other activator selected from a water soluble organic acid activator and an inorganic acid activator, and a solvent mixture. The acid activators are present in an amount which essentially neutralizes the amine.
