About Lead Free Solder (PbF)

Distribution of PbF PCB:
PCBs (manufactured) using lead free solder (PbF) will have a stamp on the PCB.

Caution:
I Lead free solder has a higher melting point than standard solder. Typically the melting points is 35 °C - 40 C
(95 °F - 104 °F) higher. Please use a soldering iron with temperature control and adjust it to 360 °C - 370 °C
(680 F - 698 °F). In case of using high temperature soldering iron, please be careful not to heat too long.
I Lead free solder will tend to splash when heated too high (600 °C / 1112 °F).
0 Lead free solder (Sn - 3.0Ag - 0.50u) or equivalents are recommended on repairing our lead free soldered PCB.
