Is there a "correct" way to create a through hole pad with different diameters on the top and bottom (same drill size of course)?
I've created a part that attaches with a small screw with a spacer on the opposite side. The bottom pad needs to be large (0.3inches) to cover the area under the bolt head.
The top pad just needs to be large enough for the plated through hole. Using a standard pad (large diameter on both sides) makes routing very difficult in that area.
I created a circle around the pad in the bottom copper and solder stop layers for now. This works but always generates a DRC error which I have to ignore.
In Orcad and Altium I simply make the correct padstack -- is there some type of equivalent in Eagle?
Thank you for your help,
