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.
