Fred-
I've just finished a board with a "Microstar" BGA-240 with 0.8mm pitch.
I used 5mil trace and spacing with a 20mil via pad, 11mil drill . The
PCB is 4 layers (2 signal and 2 power/ground) and is 0.062" thick. So
far the PCB house hasn't had a problem with fabrication. Escape routes
can be tricky with 4 layers, but it worked.
