The AIM Solder 13408 SAC305 Water-Soluble WS482 Cored Solder Wire is a water soluble, halide-free, flux-cored wire that is highly active and compatible with water-soluble solder paste chemistries. WS482 offers improved thermal stability, allowing it to be processed with standard or high-temperature alloys. It also offers residues that are non-corrosive and therefore may be used without cleaning for applications where conductivity will not cause a problem (such as soldering wires). Post-process residues are safe to remain on many assemblies for up to two to three days. WS482 produces excellent tarnish and oxide removal, it will not tarnish PCBs, copper, or solder joints, and offers excellent wetting and soldering characteristics.
AIM SAC305 is a lead-free alloy that contains 96.5% tin, 3% silver, and 0.5% copper. This alloy falls under the JEIDA recommendation for lead-free soldering. It may be used with most existing equipment, processes, coatings, and flux chemistries.
