We use microvias for these kinds of BGAs.

Subject: [PCB_FORUM] micro vias or thin traces
questions i asked our board house, but i didn't get a response. I
ordered the IPC book but it hasn't arrived. Getting desperated. Right
now i need to know if board houses can do 2.6 mil traces.
I'm trying to lay-out a board using a .5mm pitch BGA. The pads are .012
mils which leaves about .008 mils of space between pads. We are using
the two outside row so we could do this without vias, but that would
mean 2.6 mil trace with 2.6 mil space from pads. I would like to know
what kind of technology we can apply to this dense package.
If i can't use traces i will use 12 mil pad with 8 mil drill, is this
possible? Can your shop do micro via's? If so, can i get dimensions to
use for creating pads.
Thanks for any input.
