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. )
