I recently had the same problem and it drove me nuts. Finally discovered that I was using one fiducial twice instead of two different fiducials. Regards Bert

I'm with hoss67. Trust the local pcb fids. Have you run the camera down one edge of the board to see if it runs off due to a poorly scored breakaway? Some fab houses do not hold very tight tolerances for breakaways.

From looking at your images I would say it could be poor solderability on the terminations of the component itself. Can you get your hands on a different date code and try them out?

Solder mask misalignment: mismatch in registration between the solder mask and the features on the PCB. It when the things that are supposed to covered are not covered by the solder mask.

I will try to get a pix for heels. Normal IPC standard Yes, all for sides are the same (ignore the little misalignment, usually that is fine). I wonder if the IC is maybe too lite and 'swims' on the liquid tin and if it would help to put some weig

It turns out it was a misaligned fiber sensor on station 12?, the after rotation nozzle verification.
