About lead free solder (PbF)

This model uses lead free solder (PbF). For repair use only lead free handsolder.
Caution:
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). When soldering or unsoldering, please
completely remove all of the solder on the pins or solder area and be sure to heat the soldering points with the Pb free solder
until it melts enough.
