Installing Heatsink
For thermal dissipation, a heatsink enables the CEM881’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 heat spreader.
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 four assembly holes for installing heatsink plate.
Use the four screws to secure the heatsink plate to the CEM881. Be
careful not to over-tighten the screws.
Note: When installing CEM881 on CEB94006, please add stand-off and
secure with nut. Then, use the screws to secure the heatsink
plate to the CEM881.
