1. ABOUT LEAD FREE SOLDER (PbF: Pb free)
Note:
In the information below, Pb, the symbol for lead in the periodic table of elements, will refer to
standard solder or solder that contains lead.
We will use PbF solder when discussing the lead free solder used in our manufacturing process
which is made from Tin (Sn), Silver (Ag), and Copper (Cu).
This model, and others like it, manufactured using lead free solder will have PbF stamped on
the PCB. For service and repair work we suggest using the same type of solder although, with
some precautions, standard Pb solder can also be used.
Caution
- PbF solder has a melting point that is 50°F ~70°F (30°C ~ 40°C)
higher than Pb solder. Please use a soldering iron with
temperature control and adjust it to 700°F ± 20°F (370°C ± 10°C). In
case of using high temperature soldering iron, please be careful
not to heat too long.
- PbF solder will tend to splash if it is heated much higher than its
melting point, approximately 1100°F (600°C).
- If you must use Pb solder on a PCB manufactured using PbF
solder, remove as much of the original PbF solder as possible and
be sure that any remaining is melted prior to applying the Pb
solder.
- When applying PbF solder to double layered boards, please check
the component side for excess which may flow onto the opposite
side (See the figure below).
