| Printed mounting blocks. These stack like legos,
15mm high for now.

| However, a populated wedge has silicon all the way to the top, as well as wirebond encapsulation compound. | 
| ||
| On the back, there are graphite pads, originally for registration and heat transfer. | 
| ||
| The spacing between planes in the FVTX was 80 mm, and each
wedge has its own custom cable.
Image from FVTX%20cooling%20routing%203-8-2010.easm Disks do not exactly line up: they are rotated by multiples of 0.9375° |

| For the small prototype, an existing ROC will be used. Because
of constraints of the cables, the placement of the wedges relative
to the ROC is the same as in the FVTX. Since all cables from a given
disk have the same angular offset, it is not possible to make the
wedges line up.
The dark box will have to enclose much of this whole assembly.

If the enclosure boundary is just to the left of the connectors, all
the hot chips are on the outside.
