4 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. (Fig 4.1)
4. Do not turn the variable resistor (laser power adjustment). It has already been adjusted.
·
Grounding for electrostatic breakdown prevention
1. Work table grounding. (Fig 4.2)
Use the anti-static wrist strap to discharge the static electricity from your body.
2. Work table grounding. (Fig 4.2)
Put a conductive material (sheet) or steel sheet on the area where the traverse deck (optical pickup) is place, and ground
the sheet.
Caution:
The static electricity of your clothes will not be grounded through the wrist strap. So, take care not to let your clothes touch the
traverse deck (optical pickup).
Caution when replacing the Traverse Deck
The traverse deck has a short point shorted with solder to protect the laser diode against electrostatics breakdown. Be sure to
remove the solder from the short point before making connections.
