Darshan,
Besides what Steve has pointed out you may also want to consider the
mechanical stress (sheer) you are going to put on the part using this
type of via.

Subject: [SI-LIST] BGA routing
Hi All,
I have one general question regarding BGA routing. I have seen many BGA
boards and nobody puts via exactly below the BGA pad. Most of the times,
we generate Fanout outside the BGA pad. Is there is a specific reason
for that? I think we can save lot of space if we put via exactly below
BGA pad. Is there will be any problem if we put via exactly below the
pad of BGA? Thanks.
Best Regards,
Darshan Mehta
