Installing Qseven Module and Thermal Solution
For thermal dissipation, a heatsink enables the components on the Qseven module 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 heatsink.
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 Qseven module. The thermal pads on the
heatsink are designed to make contact with the necessary components on the Qseven
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 Qseven module. This is especially critical for
Qseven modules that have higher CPU speeds (for example 1.46GHz 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. Fix the heatsink
plate to the Qseven module and install to carrier board. Be careful not to over-tighten the
screws.
