FreeLists / si-list / [SI-LIST] 1 mm BGA and two traces between balls

["Steven M. Waldstein" <swldstn@xxxxxxxxxxxx>]

I'm told that some people have been able to 
achieve routing two traces between the vias
that create a picked fence when using a 1mm BGA.

If you have achieved this please let me know. Also
can you share your trace width and space, via drill size
and pad and antipad clearance to achieve this?

Any help here is appreciated.

Thanks in advance.
