Does anyone have or know of any published guidelines for BGA layout on PWB's so that they can be tested. Specifically using micro vias? If anyone has any input regarding other test considerations for BGA devices I'd like to hear from you as well.

We are just getting into BGA's and the pitch of via's is presenting a problem for our ICT bed of nails.

Thanks, Robert C.

Make every effort to distribute the test pads, because if you keep them massed at the ball, it would be a bijundo kick in the BGA rear section, when all of those pins released.
