Suggested Pbf Solder - Panasonic KX-TCD540NZM Service Manual

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).
