NIHON SUPERIOR CO., LTD.

NIHON SUPERIOR CO., LTD. is a Japanese manufacturer of metal-joining materials for the electronics industry, headquartered in Suita City, Osaka. The company was founded in 1966 by Toshiro Nishimura, initially to market flux products imported from Superior Flux Mfg. & Co. of Ohio, United States, through Matsushita Electric Trading Co., Ltd. From that starting point it broadened into a specialist supplier of soldering and brazing technologies, gathering advanced products from around the world and distributing them to the metal-joining industry while gradually building its own manufacturing and sales network. The company's product range covers lead-free solder, lead-containing solder, soldering flux, brazing alloys, nonferrous metals and the Alconano nano-silver paste line. Its best-known offering is SN100C, a lead-free solder alloy with a tin-copper-nickel-germanium composition that contains no silver, which the company presents as a cost-saving and reliable alternative to conventional silver-bearing lead-free solders. NIHON SUPERIOR states that the cumulative number of products joined with SN100C has exceeded 2.4 billion units, and the basic Sn-Cu-Ni composition is registered in the international ISO standard. NIHON SUPERIOR describes itself as a global company with manufacturing and sales centers in Japan as well as in Asia and Europe, and with business partnerships with overseas companies. Its official news stream references a Thailand subsidiary, DKL Metals exhibiting at a UK exhibition, and recognition from customers such as TDK (Malaysia) Sdn. Bhd. The company is led by President and CEO Tetsuro Nishimura and reported 99 employees as of April 1, 2022, with capital of JPY 90,000,000. It is a private company and a member of industry organizations including the Global Electronics Association, iNEMI and the HDP User Group. Positioned at the intersection of electronics manufacturing and environmental responsibility, NIHON SUPERIOR frames its development around the themes of globalization and the environment, promoting lead-free soldering and SDG-related initiatives. It participates in trade shows such as electronica India, IPC APEX EXPO and SMTA International, and engages in industry activities including sponsorship of the IPC Hand Soldering and Rework Competition Japan.

NIHON SUPERIOR CO., LTD. was founded in 1966 by Toshiro Nishimura, who established the company to market products of Superior Flux Mfg. & Co. of Ohio, United States, imported through Matsushita Electric Trading Co., Ltd. The company was inaugurated on May 1, 1966 and formally established on December 5, 1966. Its early business was built on importing and distributing specialist soldering and brazing materials: in December 1966 it began distributing brazing alloys from Unibraze of the United States, in February 1967 it started distributing products of Gasflux Co. of the United States, and in September 1969 it began distributing products of Multicore Solders Ltd. of England. The company expanded its physical footprint early. In November 1969 it completed a new main office building at Mondo Okada-Cho in Nishinomiya, Hyogo Prefecture. In February 1970 it concluded an agency agreement with Matsushita Electric Trading Co., Ltd. for distribution of imported related products in Southeast Asian markets including Japan. In May 1971 it installed a new type of wire forming machine to produce brazing materials for gas brazing, and sales of formed brazing materials increased. In November 1972 it completed construction of a company dormitory and warehouse in Takarazuka, Hyogo Prefecture. In September 1974 it established Superior Kogyo Co., Ltd. as a subsidiary to form brazing alloy. In February 1977 it moved its main office to the Esaka Building of Matsushita Electric Trading in Suita, Osaka, and completed construction of a distribution center there; in March 1977 it opened a Tokyo branch. In September 1978 it completed a No. 2 warehouse at the Esaka Distribution Center. In November 1981 it started distribution of Micro Welder equipment from MIG.O.MAT Schweissmachinen GmbH of West Germany. Over the following decades NIHON SUPERIOR shifted from being primarily an importer and distributor toward becoming a manufacturer of metal-joining materials in its own right, developing its own alloys and related products. Its most significant technical contribution is SN100C, a lead-free solder alloy with a tin-copper-nickel-germanium composition that contains no silver. The company states that the basic Sn-Cu-Ni composition is registered in the international ISO standard, and that the cumulative number of products using SN100C for joining electronic components has reached more than 2.4 billion units. SN100C is presented as addressing common problems of conventional lead-free solders such as icicles and bridges, insufficient wetting, shrinkage and cracks, copper erosion and intermetallic compound growth. By the 2020s the company described itself as a global company with manufacturing and sales centers in Japan as well as in Asia and Europe, and with business partnerships with overseas companies. Its corporate profile lists a head office at NS Bldg., 1-16-15 Esaka-Cho, Suita City, Osaka, capital of JPY 90,000,000, and 99 employees as of April 1, 2022. Tetsuro Nishimura serves as President and CEO. The company is a member of industry organizations including the Global Electronics Association, iNEMI and the HDP User Group, and it maintains an active exhibition and awards program, appearing at events such as electronica India, IPC APEX EXPO and SMTA International, and receiving recognitions including the Prime Minister's Hibiscus Award 2024/2025 and recognition from TDK (Malaysia) Sdn. Bhd. It also operates a Thailand subsidiary and is associated with DKL Metals, which exhibits at UK exhibitions.
