1. As the melting point temperature of the lead free solder
is about 30°C to 40°C (50°F to 70°F) higher than that of
the lead solder, be sure to use a soldering iron suitable
to each solder.

2. It lead solder must be used, be sure to remove lead-
free solder from each terminal section of the parts to be
replaced and from the area around it completely before
soldering, or make sure that the lead free solder and

2 lead solder melt together fully.
