We have been using a .018" (specified as .021" max.) in a .030 dia. pad for years and have not  had any problems.

Good morning everyones around the World,

I have a design/manufacturing question.  If we use a 0,018" VIA, what is
the smallest pad size we can use on this VIA without causing problem in
PCB manufacturing?

thanks
