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 figure, below).
