DFF Backdrill to Pad

PCB6453 11 days ago

Hello All,

I'm setting up my DFF constraints for backdrills on vias. The value that I have for Backdrill to antipad is 10 mils. I'm unsure of what value I need to put in for Backdrill to pad if I want the whole pad removed.

Thanks!

Hi! Are you intending to configure these values so that it sets up your backdrill? The way to set up the backdrill is actually in Manufacture > NC > Backdrill Setup

No really. I'm trying to make sure that the clearance from the edge of my backdrill is far enough from the pad that it will delete the whole pad entirely. So, I saw this on the DFF section and I was thinking that this is where I have to put in the rule.
