PCB Editor DRC errors with non-plated mechanical holes that are just holes

Jessicak

Hi All,

I have connector that requires mounting holes. These are just holes, no copper. I have defined the padstack as non-plated. and mechanical. but it seems not to undrstand that there can be no copper.

I have added a pad as padstack requires it, I have tried smaller than the drill size, equal drill size but I get the following DRC errors when I use the symbol.

Annular Ring: Pin Pad Missing mask. But I do not need or want a mask there is no copper to mask as it is drilled away

Annular Ring: Pin hole to Pad Again no annulus ring as there is no copper.

It is as if Cadence does not understand that sometimes all you want is a hole.

I guess there is something hidden somewhere that I can set that tells cadence that it is just a hole

Thanks for any help

Jessica

    Hi Jessicak on the error you receive was that error caused when you were trying to save the padstack or is the error caused when creating a footprint that uses that padstack in the editor ?

    Normally the padstack editor wont allow the creation of a padstack that gets drilled away. The idea here is that the padstack editor is trying to protect you from a possible problem.
