WebTin / bismuth and tin / bismuth / silver are the most common choices for low melting lead free solder pastes. The peak reflow temperatures provided by tin / bismuth alloys are low (160 – 170 °C) as compared to tin / lead solders (210 – 220 °C). These low peak temperatures allow for soldering of thermally sensitive assemblies. WebGold-tin eutectic solder is one commonly used die attach solder, which has many favorable attributes but is comparatively expensive.
