WS735 is an alcohol based, organically activated, water-soluble liquid flux designed specifically for wave solder applications. WS735 may be applied by automated flux sprayers, foamed, dipped, or brushed on with favorable results. WS735 is active at room temperature and maintains a wide activation range and exceptional wetting characteristics that produce bright shiny solder joints. WS 735 performs well with bare copper, solder coated, and organic coated pwbs. WS735 may be utilized with tin-lead and lead-free solder alloys. Since WS 735 flux is still active post-processing, all residues must be removed from PCBs.
