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.
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.
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).

1.1. Suggested PbF Solder
There are several types of PbF solder available commercially. While this product is manufactured using Tin, Silver, and Copper
(Sn+Ag+Cu), you can also use Tin and Copper (Sn+Cu) or Tin, Zinc, and Bismuth (Sn+Zn+Bi). Please check the manufac
turers specific instructions for the melting points of their products and any precautions for using their product with other
materials.
The following lead free (PbF)solder wire sizes are recommended for service of this product: 0.3mm, 0.6mm and 1.0mm.
