Non Plated Through Hole Settings

[tarun172]

Hi all,
        I am running into issues setting non-plated through hole in Altium. I have configured hole as mounting hole 3.08 mm non-plated, 0.127 mm solder mask expansion. When I unselect pad option as plated and run through DRC and DFM check, here is what I see:

1. DRC Error: Unplated multi-layer pad(s) detected
2. DFM error from 4PCB: Insufficient Inner Spacing.

I am trying to understand where and how to fix this issue? Can someone please advise?

Are these are 4PCB errors or Altium errors?
It seems like they support both so simply having unplated is not the issue: https://www.4pcb.com/pcb-manufacturing-custom-standard.html

Maybe you can post the pad properties you've chosen: https://www.altium.com/documentation/altium-designer/pcb-pad-properties?version=19.0
Simple pad stack or top middle bottom?

I just ran into this a month ago.

It’s not an error, just a warning, and it’s hard-coded and cannot be disabled. Just ignore it.

FYI, the Altium support forums aren’t searched by Google. Log into the Altium website and then search there. That’s the only place I found the answer.
