1Warning
Caution:
• Pb free solder has a higher melting point that standard solder; Typically the melting point is 50 - 70 °F (30 - 40 °C) higher.
Please use a soldering iron with temperature control and adjust it to 750 ± 20 °F (400 ± 10 °C). In case of using high temperature
soldering iron, please be careful not to heat too long.
• Pb free solder will tend to splash when heated too high (about 1100°F / 600 °C).
