AIM Solder AF-WS716-1GAL

WS716 Water Soluble Liquid Flux, 1 Gallon

WS716 is a halogen- and halide-free, alcohol based, organically activated, rosin-free, water soluble liquid flux designed specifically for wave solder applications. WS716 is the liquid version of the WS-477S1 series solder paste. Though designed for application via foam fluxer, WS716 may also be applied by automated flux sprayers, dipped, or brushed on with favorable results. WS716 is a buffered flux with a wide activation range and exceptional wetting characteristics that produce bright shiny solder joints. WS716 performs well with bare copper, solder coated, and organic coated pwbs. Since WS716 flux is still active post-processing, all residues must be removed after soldering.

  • WS716 is formulated for application via foam, but may be sprayed, brushed or dipped as well. Flux pots should be plastic or titanium.
  • For spraying, WS716 is ready to use directly from its container, no thinning is required. When spray fluxing, it is imperative that proper flux coverage and uniformity be achieved and maintained. A dry flux coating of 500 to 1500 micrograms per square inch is recommended as a starting point.
  • When foaming, air stones should be supplied with compressed air, free of oil and moisture. Adjust foam head to achieve a uniform distribution of small bubbles for optimum flux coverage.
  • During foaming applications it is periodically necessary to add AIM's Common Flux Thinner to replace that which is lost through evaporation.
