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.

2.3 Installing CEM Module and Heatsink
For thermal dissipation, a heatsink enables the components on the CEM module to dissipate
heat efficiently. All heat generating components are thermally conducted to the heatsink in
order to avoid hot spots. Below images illustrate how to install the heatsink.
1. There is a protective plastic covering on the thermal pads. This must be removed before
the heatsink can be mounted.
2. Each heatsink is designed for a specific CEM module. The thermal pads on the heatsink
are designed to make contact with the necessary components on the CEM module.
When mounting the heatsink you must make sure that the thermal pads on the heatsink
make complete contact (no space between thermal pad and component) with the
corresponding components on the CEM module. This is especially critical for CEM
modules that have higher CPU speeds (for example 1.0GHz or more) to ensure that the
heatsink acts as a proper thermal interface for cooling solutions.
3. This CPU module has six assembly holes for installing heat sink plat e. Use the six screws
to secure the heatsink plate to the CEM module. Be careful not to over-tighten the
screws.

Note
When installing the compact size CEM module on CEB94011, please add stand-off
and secure with nut. Then, u
se the screws to secure the heatsink plate to the
CEM module.
