Assembly
A heat spreader is included in the standard package. The heat spreader and components
required for mounting are illustrated below.
The heat spreader is designed to be mounted onto the module as illustrated below. Please
make sure the contacting sides of the heat spreader and the module are correct — the CPU
side of the module shall be facing the interface metal side and legs of the heat spreader.
Rotate horozontally so the interface metal sits right on top of the CPU. Remove any plastic
cover on the interface metal and apply thermal paste/adhesive if it is required.

Module side to chassis Heat spreader side to chassis
Rotate the module and heat spreader combo so that the I/O is facing the desired side, and
place the combo in the position of the chassis reserved for your module.
Align the screw holes of the combo to those on the chassis. The combo can be mounted
onto the chassis in two manners — 1) module side to the chassis, or 2) heat spreader side to
the chassis as illustrated below. This shall depend entirely on the design of the chassis with
regard to interior spacing, thermal, and I/O.
Place the screws that come with the standard package into the screw holes, and use a screw
driver to fasten the screws until the combo is securely fixed onto the chassis.
