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 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).
