2.8.3. Heatspreader Plate Assembly Dimensions
The module’s cooling concept uses a heatspreader plate assembly 95 mm x 125 mm (3.7“x 4.9“) fasten on the module
via the heatspreader plate standoffs, see Figure 10, pos. 4. The heatspreader plate works as a COM Express® standard
thermal interface and must be used with a heat sink or external cooling devices to maintain the heatspreader plate at
proper operating temperatures. For module and heatspreader plate height information, see Chapter 2.8.2: Module
Height.
