All

There is a board where this recently came up on.  The vendor is one we
haven't dealt with before.  I looked in the tech net archives, and did not
find an answer to this specific question.  The vias under the BGA are 22 mil
pad, 18 mil solder mask, and 12 mil hole.  I usually ask for the vias to be
filled or plugged...

My question:
1) Has anyone else had experience with running this type of board?
2)If not, has anyone had them reworked?
a)by who?
b) what was cost per via, or board?

Any shared experiences appreciated
Ron
