BGA Design/process Guru,
We are designing board with 1mm (39.37 mils) pitch 672 pin BGA. I have the
following questions which I need urgently.
(1) What is the recommended pad size?
(2) What the recommended via size?
(3) What will be the trace width and air gap if I need to pass 2 traces? We
are limited in number layers so we want to go for double traces instead of
single trace between the pads.
re,
Ken Patel
