1. 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 soldering iron with temperature control and adjust it to 700 ±
20°F (370 ± 10°C). In case of using high temperature soldering iron,
please be careful not to heat too long.
- Pb free solder will tend to splash when heated too high (about
1100°F/600°C)
- This lead free solder will be used for the products after serial No.
1,000,001.
