1 INTRODUCTION
1.1. INTRODUCTION
This service manual contains technical information which will allow service personnel´s to understand and service this
model.Please place orders using the parts list and not the drawing reference numbers.
If the circuit is changed or modified, this information will be followed by supplement service manual to be filed with original service
manual.
Note 1:
These movie camera is used Q-Mechanism.
Disassembly, Assembly and Adjustment Procedures for Mechanism Chassis separated volume.
Information for Q-Mechanism should be referd to the another manual as below.
Order No. : VMD0109026C8
1.2. ABOUT LEAD FREE SOLDER (PbF)
Distinction of PbF PCB: PCBs (manufactured) using lead free solder will have a PdF 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.
