We are having the same problem on one of our assy. Not sure of the via size but it close as is the number. Quality is handling this with the vendor. I will let you know what comes about. In our case we have 3 out of 15 boards with open vias.

Subject: [TN] PCB_OPEN_VIAS_PROBLEMS
We are having 6 layer boards contract manufactured and are having difficulty
with open vias at random places on the finished (assembled)PCB.
The PCBs have 15mil vias (lots of them 400 or so).
Does anybody have any success stories in this area. I Would love to hear
them.
Thanks in Advance
