Cautions to be taken when replacing the optical pickup
The optical pickup may break down due to the static electricity of human body. Take proper
protection measures against static electricity before repairing the parts around the optical pickup. (See
the page describing the PREVENTION OF STATIC ELECTRICITYDISCHARGE.)
1. Do not touch the areas around the laser diode and actuator.
2. Do not judge the laser diode with a tester. (The tester will be damaged easily.)
3. It is recommended to use a destaticized soldering iron for short-circuiting or removing the
laser diode. (Recommended soldering iron) HAKKO ESD Product
4. Solder the land of the flexible cable in the optical pickup.
Note:
❍
When using a soldering iron which is not destaticized, short-circuit the terminal face of
the flexible case with a clip. After that, short-circuit the land.
❍
After the repairing work is completed, remove the solder according to the correct
procedure shown in this Technical Guide.
