Almost there, but not quite – the backplane was printed reversed on the bottom side, so I need to get it redone. I accidentially sent the PCB vendor a reversed image for backplane bottom, and they blindly made it backwards. I need to get a new batch of backplane boards made before I can take money or ship. The PCB vendor have generously offered to redo and expedite the replacement backplane PCBs.

The good news is that everything lines up nicely, with no issues. The other cards pass the visual inspection and mechanical fit tests.
