3. Static Electricity Countermeasures
The laser diode inside the traverse unit (optical pickup) can be damaged by static electricity from your body. Be sure to take static
electricity countermeasures when working around the optical pickup.
1. Ground yourself
Use an anti-static wrist strap to discharge static electricity from your body.
2. Ground the workbench
Lay a conductive material (sheet) or steel sheet on the surface where the traverse unit (optical pickup) is to be placed, then
ground the sheet.
3-1. Static Electricity Countermeasure Methods
Solder the land in the flexible cable of the optical pickup.
Notes
• Be sure to do this before disconnecting the flexible cable of the optical pickup from the traverse P.C.B.
• Use an anti-static soldering iron to short-circuit and unshort-circuit laser diode.
(Recommended soldering iron: Hakko with ESD countermeasure)
• After you have finished repairing the laser diode, follow the correct procedure to remove the solder from the short-circuit
location.
