ESD Precautions
Computer boards have integrated circuits sensitive to static electricity. To prevent chipsets
from electrostatic discharge damage, please take care of the following jobs with precautions:
Do not remove boards or integrated circuits from their anti-static packaging until you are
ready to install them.
Before holding the board or integrated circuit, touch an unpainted portion of the system
unit chassis for a few seconds. It discharges static electricity from your body.
Wear a wrist-grounding strap, available from most electronic component stores, when
handling boards and components.

For thermal dissipation, a heatspreader enables the PICO822’s components to dissipate heat
efficiently. Images below illustrate how to install the heat spreader.
Installing Heatspreader
The PICO822 has four assembly holes for installing heatspreader plate. Align both of them and
use the four screws to firmly secure the heatspreader plate to the PICO822. Be careful not to
over-tighten the screws.
