2.3 Installing Heatsink

For optimum performance SCM186 has to be cooled by a passive heatsink optionally available
for ordering. For thermal dissipation, the heatsink enable the SCM186 components to dissipate
heat efficiently. All heat generating components are thermally conducted to the heatsink in order
to avoid hot spots. Below procedures illustrate how to install the heatsink on SCM186.

2.3.1 Heatsink

The heatsink is designed for the SCM186 module. The thermal pad on the heatsink is designed
to make contact with the necessary components on the SCM186 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 SCM186 module. This is especially critical for SCM186 module that
is with high CPU speed to ensure that the heatsink acts as a proper thermal interface for
cooling solutions.
This SMARC module has four assembly holes for installing heatsink. Use the four copper pillar
screws and four screws to secure the heatsink to the SCM186. Be careful not to over-tighten
the screws.
