Nihon Superior Co. Ltd., a supplier of advanced soldering materials to the global market, announces that its Senior Technical Advisor Keith Sweatman will present “The Effect of Composition on the Thickness Morphology and Growth of Interfacial Intermetallic in Pb-Free Solders” at the upcoming TMS Annual Conference, scheduled to take place March 11-15, 2012 at Walt Disney World Swan and Dolphin Resort in Florida. The presentation will take place during the session, titled “Pb-Free Solders and Other Materials for Emerging Interconnect and Packaging Technologies: Solder Alloy Design for Challenging Applications” on Wednesday, March 14, 2012 at 10:15 a.m.

The intermetallic compound layer that forms at the interface between a solder and the substrate is generally regarded as an important part of the joint that can affect its reliability in service. The nature of the intermetallic and, most importantly, the rate at which it grows at the elevated temperatures to which a joint may be subjected in service, varies with the alloy.  In this paper, the authors report the results of study of the formation and growth of the intermetallic layer formed by eight alloys that are representative of solders currently in use or under consideration. These results could provide a guide to the selection of lead-free solders for particular applications.  

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.
