Hi all, I'm looking for some help. I've got some 1mm BGAs on my board, and I need to get two between routing on the inner layers without going to uVias. I'm currently trying with .012" FHS vias, but they don't do two between. The board is .070" thick and I can go to an 8/1 aspect ratio. Give me your best shots... TIA.
