Nihon Superior Co. Ltd., an advanced joining material supplier, will exhibit in Booth #532 at SMTA International, scheduled to take place Sept. 19-20, 2017 at the Donald Stephens Convention Center in Rosemont, IL. The reliability of the company’s SN100C lead-free alloy has been proven in a wide range of electronics assembly products. The eutectic character of the silver-free SN100C alloy and the associated high fluidity provides faster wetting and increased spreadability over SAC305, which is beneficial in wave soldering and hand soldering applications as well as in reflow.
During the show, the company will showcase solder paste containing the newly developed SN100CV alloy that offer solutions for some of the challenges the electronics industry is now facing, such as improvements in reliability and thermally stable joining.
SN100CVTM P506 D4 is a lead-free, no-clean solder paste with a basic composition of (Sn-Cu-Ni+Ge+Bi). This new alloy has an addition that enables thermally stable solder joints even after thermal cycling. Unlike silver-containing alloys that derive their strength from a dispersion of fine particles of eutectic Ag3Sn, SN100CV gains its strength from solute atoms in the tin matrix of the joint. The unique ability of SN100CV P506 D4 to survive long-term storage at room temperature allows simplification of stock management while meeting all the requirements of modern reflow soldering processes.
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.
