The SN-100MA-S is a premium lead-free solder bar specifically engineered for wave soldering and selective soldering processes where dross reduction is a primary concern. This high-purity Sn99.3 alloy is formulated with specialized micro-additives that significantly improve wetting speed and joint reliability while drastically reducing the formation of dross in the solder pot. With a melting range of 227-230°C, it provides a stable and consistent soldering environment, resulting in shiny, high-quality solder joints that are comparable to traditional leaded solders in appearance. The 1kg extruded bar format ensures easy handling and consistent replenishment of the solder reservoir. This alloy is the ideal choice for manufacturers looking to reduce material waste and maintenance costs while meeting strict RoHS compliance and maintaining peak electrical performance across complex printed circuit board assemblies.
