0.6 STATIC ELECTRICITY PRECAUTIONS
Before removing the board from its anti-static bag, read this section about static electricity precautions.
Static electricity is a constant danger to computer systems. The charge that can build up in your body
may be more than sufficient to damage integrated circuits on any PC board. It is, therefore, important to
observe basic precautions whenever you use or handle computer components. Although areas with
humid climates are much less prone to static build-up, it is always best to safeguard against accidents
that may result in expensive repairs. The following measures should be sufficient to protect your
equipment from static discharge:
 Touch a grounded metal object to discharge the static electricity in your body (or ideally, wear a
grounded wrist strap).
 When unpacking and handling the board or other system components, place all materials on an
anti-static surface.
 Be careful not to touch the components on the board, especially the “golden finger” connectors on
the bottom of the board.
