Grounding for electrostatic breakdown prevention

• As for parts that use optical pick-up (laser diode), the optical pick-up is destroyed by the static electricity of the working environ-
ment.
Repair in the working environment that is grounded.
2.3.1. Worktable grounding
• Put a conductive material (sheet) or iron sheet on the area where the optical pickup is placed and ground the sheet.
2.3.2. Human body grounding
• Use the anti-static wrist strap to discharge the static electricity form your body Figure 2-2.
