3.4.5 Module Assembly Hardware
The SMARC sAT30 module is attached to the carrier with four M2.5 screws. A 4mm length screw is usually used. The
attachment holes are located on the corners of the module. Attachment holes have a 6mm diameter pad, 2.7 mm dia
drill hole as shown Figure 7: SMARC sAT30 Top side components.
3.4.6 Module Cooling Solution Attachment
Two Penn Engineering and Manufacturing (PEM) ( www.pemnet.com ) “SMTSO” surface mount standoffs with M2.5
internal threads and 3mm stand-off height are soldered into the Module top side, adjacent to the Tegra SoC. They are
provided for the attachment of a heat spreader or heat sink, independent of the corner mounting holes. The PEM
SMTSO parts have excellent pull- strength and the Module PCB will deform before the standoffs can be pulled out.
The heat sink/heat spreader mounting holes are shown in Figure 7: SMARC sAT30 Top side components. The Heat
Spreader is secured to the Module with two 6mm flathead M2.5 screws.
For a large-area heat spreader or heat sink, the corner holes should be used as well, with suitable standoffs.
