We have seen the same problem with missing fiducials. Our supplier is
using horizontal hot air leveling equipment. The fiducials were being
'ripped' off by a roller at the exit of the machine. Like your
problem, the missing fiducials were isolated and, naturally, at the
same location on every board. Our supplier changed panelization of
the board and added some thieving circles around the fiducials to
prevent future occurrences.
