  • Water soluble condensation soldering flux
    Patent number: 4701224
    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.

  • Water soluble flux
    Patent number: 4478650
    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.
