1.2. About Lead Free Solder (PbF)
Distinction of PbF PCB:
PCBs (manufactured) using lead free solder will have a PbF stamp on the PCB.
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.
