General Descriptions - Panasonic NV-SV120EG Service Manual

If the circuit is changed or modified, this information will be followed by supplementary service
manual to be filed with original service manual.
Note:
Adjustment procedures, Disassembly Procedures and Assembly Procedures for Mechanism
Chassis are separate volume from this service manual. / Please refer to the service manual for Z-
Mechanism Chassis. (Order No. VRD9802005C2)
1.2. ABOUT LEAD FREE SOLDER (PbF)
Distinction of PbF PCB:
PCBs (manufactured) using lead free solder will have a PbF stamp on the PCB.
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 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.
