1 ABOUT LEAD FREE
SOLDER (PbF)
Distinction of PbF PCB:
PCBs (manufactured) using lead free solder will have a PbF
stamp on the PCB.

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.
