You can also take the following steps to prevent damage from electrostatic
discharge (ESD):
• When unpacking a static-sensitive component from its shipping
carton, do not remove the component from the antistatic packing
material until you are ready to install the component in your system.
Just before unwrapping the antistatic packaging, be sure to discharge
static electricity from your body.
• When transporting a sensitive component, first place it in an antistatic
container or packaging.
• Handle all sensitive components in a static-safe area. If possible, use
antistatic floor pads and workbench pads and an antistatic grounding
strap.
