4 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 thmelting 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).
