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).
