The AIM Solder 14220 SN100C FastCore Rosin Flux Solder Wire is a resin-based flux-cored solder wire designed to offer excellent wetting characteristics, bright and shiny solder joints, and lead-free compatibility. This product is very active and is recommended for fast cycle time soldering. The FastCore flux promotes good thermal transfer, offering excellent solder penetration into plated through holes or surface-mount interconnections. FastCore produces low-to-medium, clear post-process residues.
AIM SN100C is a lead-free solder alloy developed by Nihon Superior in Japan that is comprised of tin, copper, and a small amount of nickel. SN100C offers user-friendly properties and has been proven in commercial production for more than six years. The patented addition of nickel imparts to the cost-effective tin-copper eutectic and improves the wetting and flow properties that make it possible to achieve excellent results in wave soldering at process temperatures comparable with those used with 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.
