9.2 Thermal Solution
9.2.1 Heat Spreaders
The function of the heat spreader is to ensure an identical mechanical profile for all COM Express modules. By using a heat spreader, the
thermal solution that is built on top of the module is compatible with all COM Express modules.
9.2.2 Heat Sinks
A heat sink can be used as a thermal solution for a specific COM Express module and can have a fan or be fanless, depending on the
thermal requirements.
9.2.3 Installation
Install a heat spreader or heat sink using the following instructions.
Step 1: Before mounting the heatsink, install the required memory modules onto the SODIMM socket(s) on the COM Express module.
Step 2: Remove the protective membranes from the thermal pads.
Step 3: Assemble the heatsink onto the COM Express module.
