1. General characteristics

S-Sn99Ag0,3Cu0,7 solder manufactured in the first melt of tin, silver and copper in continuous casting process in air-free environment; afterwards extruded, in order to eliminate oxide occurrence. Designed as an economical replacement for the solder alloy Sn63Pb37, consistent with the guidelines of the RoHS Directive. Specially selected trace elements of metals improves dispersed, weld appearance and protect against rapid oxidation during the soldering process.
