Hi,

I would like some idea's or suggestions concerning a board that has a 0.5mm
BGA.
Specifically, I would like to know what type of via was used to break out.
We are currently designing a board that will have 12 layers and we are
going
to use micro-vias for this type of BGA.

Is there any other way ?

Thanks in advance,
