Soldering temperature;
The soldering temperature is only 20-30 °C above its melting point (about 300 ~ 310 C). Because the alloy is eutectic, minimal superheat is needed for the wetting and flowing in the soldering process. It also freezes quickly resulting in a shorter
soldering cycle. This temperature range is suitable for high-reliability component packaging. The components could also be safe for subsequent assembly with a Pb-free assembly solder. These solders typically require an assembly temperature up to 260 °C
