WS715M is a neutral alcohol-based, organically activated, rosin-free, water-soluble liquid flux designed specifically for wave solder applications. Though designed for application via foam fluxer, WS715M may also be applied by automated flux sprayers, dipped, or brushed on with favorable results. WS715M is a buffered flux that has a wide activation range and good wetting characteristics that produce bright shiny solder joints. WS715M performs well with bare copper, solder-coated, and organic-coated pwbs. Since WS715M flux is still active post-process, all residues must be removed from pwbs.

WS715M has a sealed shelf life of one (1) year when stored at room temperature. Do not store near fire or flame. Keep away from sunlight as it may degrade the product. WS715M is shipped ready-to-use, no mixing necessary. Do not mix used and unused chemicals in the same container. Reseal any opened containers. Storage conditions range from 4-40°C (40-100ºF).

Application

WS715M is formulated for application via spray, foam, brush, or dip. WS715M is ready to use directly from its  ontainer, no thinning required. When spray fluxing, proper flux coverage and uniformity are imperative. A dry flux coating of 500-1500 micrograms per square inch is typical.
