Thermal Solution Assembly 

The reference thermal solution is a passive extruded heatsink with thermal and mechanical 
interfaces. It is attached using a clip with each end hooked through an anchor soldered to the 
board. Figure 8 shows the reference thermal solution assembly and associated components. 

Figure 9 and Figure 10 show alternate views of the reference solution. Full mechanical drawings of 
the thermal solution assembly and the heatsink clip are provided in Appendix B. Appendix A 
contains vendor information for each thermal solution component.
