3 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 (PbF) used in our manufacturing process and discussed below is (Sn+Ag+Cu).
Those are Tin (Sn), Silver (Ag) and Copper (Cu), although other types are available.

This model uses PbF in its manufacture due to environmental conservation issues. For service and repair work, we would suggest
the use of PbF as well, although Pb may be used.

PCBs manufactured using lead-free will have the “PbF within a leaf Symbol” stamped on their back.
Caution
• PbF has a higher melting point than that of 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).
• PbF 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 PbF on the pins or solder area before applying Pb. If this is
not practical, be sure to heat the PbF until it melts, before applying Pb.

• After applying PbF to double layered boards, please check the component side for excess solder which may flow onto the
opposite side (see Figure 2).

Suggested PbF
There are several kinds of PbF available for purchase. This product uses Sn+Ag+Cu (tin, silver, copper) solder. However,
Sn+Cu (tin, copper) and Sn+Zn+Bi (tin, zinc, bismuth) solders can also be used.
