About lead free solder

All of the P.C.B.s installed in this unit and solder joints are soldered using the lead free solder.

Among some types of lead tree solder currently available, it is recommended to use one of the following types for the
repair work.

0 Sn + Ag + Cu (tin + silver + copper)
0 Sn + Cu (tin + copper)
0 Sn + Zn + Bi (tin + Zinc + bismuth)

Caution:
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.
