Preventing Electrostatic Discharge Damage
Figure 8
Attaching the ESD Wrist Strap Clip to the System Ground Lug Screw
In addition, follow these guidelines when handling modules:
•
Handle modules by the metal carrier or edges only; avoid touching the printed circuit boards or
connectors.
•
Place a removed module component board-side-up on a properly grounded antistatic surface or in a
antistatic bag. If you plan to return the module to the factory, immediately place it in an antistatic
bag.
•
Never attempt to remove the printed circuit board from the metal carrier.
Caution
For safety, periodically check the resistance value of the antistatic strap. The measurement should be
between 1 and 10 megohm (Mohm).
