Heatsink Design
NOTE: The heatsink is insufficient for cooling the card on platforms with little or no forced airflow (e.g. a PC with a SPEC). The recommended cooling solution for PCs is an add-on fan for the SPEC card (see SPEC Fan Design).
The heatsink is CNC-machined from a single piece of aluminium. It attaches to the board by replacing the stand-offs next to the FMC connector and by thermoconductive adhesive tape applied to the most heat-dissipating components (i.e. the AD9516 PLL and the SY89285 delay lines) as well as some empty spots on the PCB.
The design (STEP/IGES/DXF formats) is hosted in the repository
