Hello
I need to place an NPTH(Non-Plated) hole in our design. whenever we place a hole, it appears with a solder mask opening(tstop layer). And we don't need the solder masking opening.
So in eagle, there is an option for removing mask opening for pads/vias. But there is no option for drill without the solder mask opening.
Please help me out how to place a drill(NPTH hole) without a solder mask opening.
