So I had recently a PCB made, and assembled. It came back perfect !
But, when I was placing another order, I noticed that there was a "DFM Analysis"
from that project, and I took a quick peek at it. Apparently, JLCPCB guys had to "fix"
the placement. Please see this image:

It appears from this image that the placement was "rotated".
However, before placing the order, I DID verify the PCB and placements in the 3D viewer
and JLCPCB Gerber viewer. I did not see any such errors.
My Question is, what did go wrong ? How can I avoid this type of errors in the future ?
It might be not as obvious on more complex PCBs what needs to be done ..
Many Thanks,
rudi
