SN100C P602 is completely halogen-free, which means there are no intentional halogens of F, Cl, Br or even I hidden in the chemistry. The SN100C alloy delivers a silver-free stable microstructure in an alloy that can accommodate long-term cyclic strains and impact strains to which a solder joint can be subjected.
SN100C P602 has smooth bright fillets with fewer shrinkage defects and a stable microstructure with minimal growth of the interfacial intermetallic, resulting in highly reliable solder joints. SN100C provides excellent printing and reflow in fine-pitch circuitry, low hot and cold slump, and good coalescence and wetting with no solder balls.
Also at the show, Nihon will highlight its NS-F900, a robust, heat resistant, no-clean rosin containing wave soldering flux that is completely halogen-free. It provides high performance with high preheat temperature profiles, resulting in high topside board temperatures (up to 125°C) and long dwell times that may be required for thick boards and dense, complex assemblies while being environmentally friendly. NS-F900 is specifically designed for use with SN100C (Sn-Cu-Ni+Ge) lead-free solder but applicable to all lead-free alloys as well as Sn/Pb in wave soldering.
NS-F900 is designed to provide good hole-fill and easy solder joint inspection with little residue, while meeting JIS and J-STD-004 Surface Insulation Resistance requirements. The excellent drainage results in reduced bridging or solder shorts.

Nihon Superior was founded in 1966 when it began marketing unique flux products imported from the US. The company made its mark on society by gathering the most advanced soldering and brazing technologies and products from around the world, and supplying them to companies in the metal-joining industry. A turning point for the company came when it started developing its own soldering materials and with the success of its unique SN100C lead-free solder alloy Nihon Superior has become a major player in the global market. To support the growing demand for its products Nihon Superior has established manufacturing and sales centers in Japan, China and other Asian countries and formed business partnerships with companies in other markets.
