5 Handling Precautions for Traverse Unit
The laser diode used inside optical pickup could be destroyed due to static electricity as a potential difference is caused by
electrostatic load discharged from clothes or human body. Handling the parts carefully to avoid electrostatic destruction during
repair.
5.1. Handling Optical Pickup
1. Do not impact on optical pickup as the unit structurally uses an extremely precise technology.
2. Short-circuit the flexible cable of optical pickup remove from the circuit board using a short-circuit pin or clip in order to prevent
laser diode from electrostatic destruction (Refer to Fig. 3.1 and Fig. 3.2)
3. Do not handle flexible cables forcibly as this may cause snapping. Handle the parts carefully (Refer to Fig. 3.1)
4. A new optical pickup is equipped with an anti-static flexible cable. After replacing and connecting to the flexible board, cut the
anti-static flexible cable. (Refer to Fig. 3.1)
Fig 3.1
5.2. Replacing Precautions for Optical Pickup Unit
Optical Pickup
The optical pickup by which part supply was carried out attaches the short clip to the flexible board for laser diode electrostatic
discharge damage prevention. Please remove the short clip and be sure to check that the short land is open, before connecting.
(Please remove solder, when the short land short-circuits.)
5.3. Grounding for Preventing Electrostatic Destruction
1. Human body grounding
Use the anti-static wrist strap to discharge the static electricity accumulated in your body. (Refer to Fig. 3.2)
2. Work place grounding
Place a conductive material (conductive sheet) or ironboard where optical pickup is placed. (Refer to Fig. 3.2)
Note :
Keep your clothes away from optical pickup as wrist strap does not release the static electricity charged in clothes.
