Rel61 Lead-Free Solder Alloy
REL61™ is a low-cost alternative to SAC alloys with reliability and performance characteristics equal to or greater than SAC305 and other low/no-silver solders.
REL61 has proven to reduce the formation of tin whiskers and outperform SAC alloys in thermal shock, vibration and drop shock reliability testing. REL61 exhibits superior spread, flow and wetting in production testing versus silver-free alloys.
REL61 is available in bar solder, solder wire, and solder paste.
