What are the typical dimensions of a micro via? Drill and diameter. Dimensions that are accepted by fabrication houses.

    Short answer - 4 mil drill, 12+ mil pad

    But really, it depends.  Each design house will have it's own guidelines for what it things is standard dimensions for that manufacturing capability, or advanced, or call me with your bank card number and we'll get it done.  Streamline circuits happens to be a bigger manufacturer who does a good job documenting their capability, so you can go there and see what they can build easy, with care, or with wads of cash.   Sizing the pad size is more about reliability than can it be done, so it is a bit more squishy.
