Hello everyone, I'm a newbie on PCB design, now I'm facing a problem that I tried to fix but I can't, hope you guys can give me a hand. I tried to draw 2 pads on both sides of the PCB, one on top, the other on the bottom at the same (x, y) coordinate, but when I check DRC, the software tells that the clearance between the bottom and the top layer less than DRC rule, I don't understand because I set two pads to both sides which don't connect anymore, so how can I fix it? Thanks.
