3 Precaution of Laser Diode

SL-CT582VEE

The laser diode in the traverse deck (optical pick-up) 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 pick-up).

4.1. Handling of traverse deck

(optical pick-up)

1. Do not subject the optical pick-up to static electricity as it is

extremely sensitive to electrical shock.

2. To protect the laser diode against electrostatic breakdown,

be sure that the short land of the flexible board (FFC board)

should be short-circuit by solder before pulling out the FFC.

Then inserting a short pin or similar object into the tip of the

flexible board.

(Refer to Fig. 4-1.)

3. Take care not to apply excessive stress to the flexible board

(FFC board).

4. Do not turn the variable resistor (laser power adjustment). It

has already been adjusted. (Refer to Fig. 4-1.)

Fig. 4-1.

4.2. Caution when replacing

traverse deck

The new traverse deck short-circuits by the short pin, the foil

(B) and short lands to protect the laser diode against

electrostatic breakdown. Be sure to replace to new one

following procedures.

1. Remove the short pin from the FFC, and then connect it to

the connector.

2. Cut the foil (B). (Refer to Fig. 4-1.) (Take care not to make

contact with cutting point each other.)

3. Unsolder the short lands. (Refer to Fig. 4-1.)

4.3. Grounding for electrostatic

breakdown prevention

4.3.1. Human body grounding

Use the anti-static wrist strap to discharge the static electricity

from your body. (Refer to Fig. 4-2.)

Fig. 4-2.

4.3.2. Work table grounding

Put a conductive material (sheet) or steel sheet on the area

where the traverse deck (optical pick-up) is placed, and ground

the sheet. (Refer to Fig. 4-3.)

Fig. 4-3.

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 pick-up).
