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

• Pb free solder has a higher melting point than standard solder, Typically the melting point is 30-40

°C higher.

Please use a high temperature soldering iron. In case of soldering iron with temperature control, please set it to 370±10

°C.

• Pb free solder will tend to splash when heated too high (about 600

°C).

When soldering or unsoldering, please completely remove all of the solder on the pins or solder area, and be sure to heat the sol-
dering points with the Pb free solder until it melts enough.
