Nihon Superior Co. Ltd., a supplier of advanced soldering materials to the global market, announces that it has received a Global Technology Award in the category of Soldering Materials for its SN100C (551CT) Flux-Cored Solder Wire. The award was presented to the company’s President, Tetsuro Nishimura during a ceremony that took place on Tuesday, November 15, 2011 at the New Munich Trade Fair Centre, Germany during Productronica 2011.
SN100C(551CT), the latest addition to the SN100C lead-free solder series, combines the benefits of a high reliability alloy (Sn-0.7Cu-0.05Ni+Ge) with a sustained activity core flux. The 551CT core flux is formulated for use with soldering tip temperatures up to 380°C while still retaining sufficient activity to ensure good tip separation. Compared with previous formulations, icicling is reduced by 90 percent and spattering by 95 percent. The silver-free SN100C alloy has a stable microstructure that can accommodate both the long-term cyclic strain and the impact loading to which solder joints can be subjected in service.
SN100C (551CT) has been developed specifically for sequential soldering and rework. Today, 12 years after its introduction, SN100C lead-free solder is still displacing SAC305 in many applications because of its high reliability, low copper erosion, and cost effectiveness.
Premiering in 2005, the Global Technology Awards program is an annual celebration of product excellence in electronics surface mount assembly. Premier products based on the finest examples of creative advancement in technology are chosen by a distinguished panel of industry experts.
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 the United States, and formed business partnerships with companies in other markets.
