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 (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 figure below)
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.
