soldered using the lead free solder

Among some types of lead free solder currently available,
it Is recommended to use one of the following types for
the repair work

0 Sn + Ag + Cu (tin + Silver + copper)

- Sn + Cu (tin + copper)

. Sn + Zn + Bi (tin + Zinc + bismuth)

Caution:
As the melting pomt 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
