12 Servicing Information
Caution:
•
Pb free solder has a higher melting point than standard solder; Typically the melting point is 50 - 70°F(30-40°C) higher. Please use
a high temperature soldering iron. In case of the soldering iron with temperature control, please set it to 700 ± 20°F (370 ± 10°C).
•
Pb free solder will tend to splash when heated too high (about 1100° F/600°C).
