  • Page 4 Pb free solder has a higher melting point than standard solder; typically the melting point is 50 - 70°F (30 - 40°C) higher. Please use a high temperature soldering iron. In case of the soldering iron with temperature control, please set it to 700 20°F (370 10°C). Pb free solder will tend to splash when heated too high (about 1100°F/600°C).
