ABOUT LEAD FREE SOLDER (PbF)Distinction of PbF PCB: PCBs (manufactured) using lead free solder will have a PdF stamp on thePCB.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 high temperature soldering iron. In case of solderingiron with temperature control, please set it to 700±20°F (370±10°C).- Pb free solder will tend to splash when heated too high (about1100°F/ 600°C).When soldering or unsoldering, please completely remove all of the solder on the pins or solderarea, and be sure to heat the soldering points with the Pb free solder until it melts enough.3
