I found out that "standard" PCB fabs usually start to charge extra cost if
you go below 20 mils hole diameter (0.5mm). But it much depends on the
tooling they got.
Similarly I use trace width above 8 mils (200um).

What is the standard minimum finished via size that will not add cost
too much? I do not want to specify the very small via which will drive
the price very high and at the same time not too big via size from the
real estate point of view.
