    Flat-Heatspreader Dimensions For cooling solutions where it is desirable to mount the cpuModule to a flat surface, the CMA24BT may be ordered with a flat heatspreader instead of the standard passive heatsink. Each flat-heatspreader has five mounting locations which use 6-32 UNC x 0.207” long threaded insert. Use the table below to correlate the heatsink figure to each ordering part number.
