 +Seems that the connection solution is not optimal. The Cu zone is to close to the mounting hole. So the cable scratches the solder mask and creates short circuits. My current solution is to use plastic washers to create some distance. But now the nuts on the bottom of the boards are required to directly touch the boards for a reliable connection. Microscope images of the follow.

 +Mounted the first boards on the backplane. I started again with the ALU, similar to the preproject. Some wires left. Also the zero-detection logic is not mounted yet. But so far everything seems to work perfectly!

 +  - Clearing around M2 holes bigger! The problem is that after some mountings and unmountings the soldermask gets holes and the Cu gets through. You got a short circuit than. Not good!
