2.3 Installing Heatsink & Heatspreader
For thermal dissipation, the heatsink & heatspreader enable the SCM180 components to
dissipate heat efficiently. All heat generating components are thermally conducted to the
heatsink or heatspreader in order to avoid hot spots. Below procedures illustrate how to install
the heatsink and heatspreader on SCM180.
2.3.1

Heatspreader

1. The heatspreader is designed for the SCM180 module. The thermal pad on the
heatspreader is designed to make contact with the necessary components on the
SCM180 module. When mounting the heatspreader you must make sure that the
thermal pads on the heatspreader make complete contact (no space between
thermal pad and component) with the corresponding components on the SCM180
module. This is especially critical for SCM180 module that is with high CPU speed to
ensure that the heat spreader acts as a proper thermal interface for cooling
solutions.
2. This CPU module has four assembly holes for installing heat spreader plate. Use the
four screws to secure the heat spreader plate to the SCM180. Be careful not to
over-tighten the screws.
2.3.2 Heatsink & Heatspreader
1. The heatsink is designed to work with heatspreader for SCM180 module. Before
installing the heatsink to the CPU module, please ensure that the heatspreader is
installed and then secure fore screws onto heatspreader.
