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 :

0 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 1 20°F (370 i
10°C). In case of using high temperature soldering iron,
please be careful not to heat too long.

0 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.
