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 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.
