About lead free solder (PbF)Note: Lead is listed as (Pb) in the periodic table of elements.In the information below, Pb will refer to Lead solder, and PbF will refer to Lead Free Solder.The Lead Free Solder used in our manufacturing process and discussed below is (Sn+Ag+Cu).That is Tin (Sn), Silver (Ag) and Copper (Cu) although other types are available.This model uses Pb Free solder in it’s manufacture due to environmental conservation issues.For service and repair work, we’d suggest the use of Pb free solder as well, although Pb soldermay be used.PCBs manufactured using lead free solder will have the PbF within a leaf Symbolstamped on the back of PCB.Caution- Pb free solder has a higher melting point than standard solder.Typically the melting point is 50 ~ 70 °F (30~40 °C) higher. Pleaseuse a high temperature soldering iron and set it to 700 ± 20 °F (3705
