Installing Thermal Solution
For thermal dissipation, a thermal solution enables the CEM501/511’s
components 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 thermal solution on CEM501/511.
1. There is a protective plastic covering on the thermal pads. This must
be removed before the heatspreader can be mounted.
2. Each thermal solution is designed for a specific CEM module. The
thermal pads on the heatspreader are designed to make contact with
the necessary components on the CEM module. When mounting the
heatspreader you must make sure that the thermal pads on the
heatspreader 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
heatspreader acts as a proper thermal interface for cooling solutions.
3. Before installing the heatspreader to the CPU module, please apply
thermal grease on the CPU die. This CPU module has four assembly
holes for installing heatspreader plate. Use the four screws to secure
the heatspreader plate to the CEM501/511. Be careful not to over-
tighten the screws. Then, apply thermal grease at the bottom of
heatsink and secure the heatsink on the heatspreader by another four
screws.
Note: When installing CEM501/511 on CEB94011, please add stand-off
and secure with nut. Then, use the screws to secure the
heatsink plate to the CEM501/511.
