Suggested Pbf Solder; How To Recognize That Pb Free Solder Is Used - Panasonic KX-TCD510ALV Service Manual

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).
