3.1. About Lead Free Solder (PbF)
Distinction of PbF PCB:
PCBs (manufacture d) 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 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).
· W hen soldering or unsoldering, please completely remove all of the solder on the pins or solder area, and be sure to heat
the soldering points with the Pb free solder until it melts enough.
