FreeLists / si-list / [SI-LIST] BGA routing

[Darshan Mehta <darshanmehta2k@xxxxxxxxx>]

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
