- 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.
6. Handling Precautions For Traverse Deck
The laser diode in the traverse deck (optical pickup) may break down due to potential difference
caused by static electricity of clothes or human body.
So, be careful of electrostatic breakdown during repair of the traverse deck (optical pickup).
- Handling of traverse deck (optical pickup)
1. Do not subject the traverse deck (optical pickup) to static
electricity as it is extremely sensitive to electrical shock.
2. To prevent the breakdown of the laser diode, an antistatic
shorting pin is inserted into the flexible board (FFC board).
3. Take care not to apply excessive stress to the flexible board (FFC
board). When removing or connecting the short pin, finish the job
in as short time as possible.
4. Do not turn the variable resistor (laser power adjustment). It has
already been adjusted.
