Many PCB Design tools do not have a countersink hole in the pad stack.
 
You need to call this out in your Fabrication Drawing as a Flag or Note.

How do you define/create countersink or counterbore NPTH padstacks? Do we have a design rule or standard like placing regular pads or anti-pads or keepouts?]]> Sun, 13 Sep 2015 17:39:38 +0000 https://www.PCBLibraries.com/forum/countersink-counterbore-padstacks_topic1757_post7196.html#7196
