SN100C is a lead-free solder alloy developed by Nihon Superior in Japan. It offers user-friendly properties and has been proven in commercial production since 1999. The addition of nickel improves the wetting and flow properties of the cost effective tin-copper eutectic. This makes it possible to achieve excellent results in wave soldering at process temperatures comparable to the tin-lead solder it replaces. Performance in wave soldering at least matches that of more expensive silver-containing alloys, and the resulting joints are smoother and brighter.
