What’s the smallest via BatchPCB will except on a two layer board?
With a smallest drill size of 20mil, how large do I need to make the ring around the hole? I’ve seen 40mil discussed when talking about pads. Can vias be made smaller safely?
(The traces are low voltage, low current signals only)
Thanks,
Frank
That info should be in the Batch PCB spec.

I was guessing a via was just a small plated through hole. Are vias treated differently?
No, they are just pads with holes like any others as far as most PCB suppliers are concerned. Very high performance boards sometimes have micro-vias drilled by laser, those are treated differently from the other pads.
