3.4 Thermal Solutions
There are two thermal solutions for the COM Module CT-CIB61 to dissipate
the heat. One is by using a fan sink and the other one is by using a heat
spreader.
Fan Sink 3.4.1
Step 1: Place the fan sink on top of the CT-CIB61 module.
Step 2: Use three screws (M2.5x5L) to secure the fan sink with the CT-CIB61,
as illustrated below.
Step 3: Connect the COM Express connectors on the CT-CIB61 to the
corresponding COM connectors on the Carrier Board. Make sure the four
holes at the corners of CT-CIB61 module align to the corresponding pillars on
the Carrier Board.
Step4: Use five screws (M2.5x15L) to secure the fan sink with the Carrier
Board through the corresponding holes on the CT-CIB61.
