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 materia ls 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.
