Attaching Your ESD Grounding Strap

In addition, follow these guidelines when handling modules:
• Handle carriers by available handles or edges only; avoid touching the printed circuit boards or
connectors.
• Place a removed component board-side-up on an antistatic surface or in a static-shielding container.
If you plan to return the component to the factory, immediately place it in a static-shielding
container.
• 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).
