Webtemperature than eutectic tin-lead solder’s (Sn63Pb37 or Sn63) 183°C, yet it is high enough for most soldering applications. In addition, its mechanical properties are similar to Sn63, but contain no lead. The alloy is near eutectic at its 137-139°C. Although a reflow temperature of 20-40oC above WebMelting point of lead-free eutectic solder (SAC387) is 217°C. Since lead-free eutectic solder (SAC387) features a 34°C higher melting point than traditional lead eutectic solder (Sn37Pb), the consequence is: 1).The rising temperature afterwards leads solder to be easily oxidized with chemical compound quickly growing between metals.
