ESD Precautions
Integrated circuits on computer boards are sensitive to static
electricity. To avoid damaging chips from electrostatic
discharge, observe the following precautions:
 Do not remove boards or integrated circuits from their anti-static
packaging until you are ready to install them.
 Before handling a board or integrated circuit, touch an unpainted
portion of the system unit chassis for a few seconds. This helps to
discharge any static electricity on your body.
 Wear a wrist-grounding strap, available from most electronic
component stores, when handling boards and components.
