2.2.4 Thermal Solution Important notice: 1. Please Note - the heat-spreader shipped with Advantech’s SOM product is not a "COMPLETE" thermal solution. The function of this heat-spreader is for conducting heat from SOM module to the customer's own heat-sink or cooler which is added onto this heat-spreader. 2. An extra-efficient heat-sink or cooler is required to add onto this heat-spreader to ensure the SOM module can work appropriately. 3. An inefficient heat-sink or cooler may damage the SOM module.
