5. Handling the Lead-free Solder
5.1. About lead free solder (PbF)
Distinction of PbF P.C.B.:
P.C.B.s (manufactured) using lead free solder will have a PbF stamp on the P.C.B.
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).
- When soldering or unsoldering, please completely remove all of the
solder on the pins or solder area, and be sure to heat the soldering
points with the Pb free solder until it melts enough.

7.1. Function of Power Circuit (IC1150)
1. General
We adopted IC module as the Switching Power Circuit for lower power consumption.
IC1150 is constructed with Switching materials and Control IC, and is partial resonance module.
We realized Switching Power with high efficiency, low noise and low power consumption.
