The ISIS is based on PC/104-Plus form factor standard.
The CPU module is mounted via a 220-pin stacking interface connector to the ISIS
board. An 8mm stacking height is used in order to accommodate PCI Express Mini Card
heights of up to 5mm. The vertical height of the ISIS does not fully comply with the
PC/104-Plus specification; however access to the top side PC/104 and PC/104-Plus
connectors is still possible.
A custom designed heat spreader is required for the processor and chipset. The heat
spreader is used on top of the CPU module. It connects to the ISIS through 4 spacers,
two of which go through the CPU module, and two mount directly to the ISIS. Another two
mounting holes on the CPU module are used to connect to the heat spreader.
Mechanical drawings are shown on the following page.
