The AIM Solder 13563 Sn63/Pb37 RMA Mildly Activated Rosin Core Solder Wire is a mildly activated, general-purpose wire solder for use in applications requiring good activation. RMA cored wire is active enough for excellent tarnish or oxide removal, and will produce bright shiny solder joints. RMA wire will leave slight to moderate post-process residues that may be left on non-critical applications, but should be removed from any critical applications.
AIM SN63/37 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 bridging during soldering and reducing drossing, improving flow. 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.
