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 t 20°F (370 :
10°C). In case of using high temperature soldering iron.
please be careful not to heat too long.

(about 1100°F/600°C)
