The AIM Solder 13211 Sn63/Pb37 Glow Core No-Clean Flux Solder Wire is a resin-based flux cored solder wire designed to offer excellent wetting characteristics and lead-free compatibility. This product is very active and is recommended for fast cycle time soldering. Glow Core flux promotes good thermal transfer, offering better solder penetration into plated through holes or surface mount interconnections. Glow Core wire produces low-to-medium post-process residues that are electrically safe and do not require cleaning for most applications.
AIM Sn63/Pb37 is a high clarity alloy that is composed of 63% tin and 37% lead. It goes through the Electropure™ process, which reduces suspended oxides in the solder, thus reducing drossing, improving flow, and reducing bridging during soldering. Sn63/Pb37 is a eutectic alloy with a melting point of 361°F (183°C). Typical applications are wave soldering and plating where Sn63/Pb37 is primarily used as a coating for corrosion protection, and as a base for soldering.
