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 solder may be used. 
PCBs manufactured using lead free solder will have the PbF within a leaf Symbol  
 
             stamped 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. Please use a high temperature soldering iron and set it to 700 ± 20 °F (370 ± 10 °C). 
 
Pb free solder will tend to splash when heated too high (about 1100 °F or 600 °C). 
If you must use Pb solder, please completely remove all of the Pb free solder on the pins or solder area before 
applying Pb solder. If this is not practical, be sure to heat the Pb free solder until it melts, before applying Pb solder. 
 
After applying PbF solder to double layered boards, please check the component side for excess solder which may 
flow onto the opposite side. (see Fig.3) 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Suggested Pb free solder  
There are several kinds of Pb free solder available for purchase. This product uses Sn+Ag+Cu (tin, silver, copper) solder. 
However, Sn+Cu (tin, copper), Sn+Zn+Bi (tin, zinc, bismuth) solder can also be used. (see Fig.4)
