[PCB_FORUM] Re: Removing unused pad rings on inner layers DURING design...

Austin,

I have to ask the question..

What size anti-pad are you using for your vias ?  (Hole size + ?)

In one of your previous responses you indicated that you will still
have a plane reference when routing thru the suppressed pad area
so I wanted to know how you are accomplishing this.

Thanks,
Mike

BTW:  I think it would be a cool option to suppress the via pads
so you are able to route more traces thru between vias but I
don't know if I would really use it.

Hi Jim,

With a 10 mil drill, yes.  This is the technology that has to be used, and
again, it will work, so there should be no need to go to another more
expensive technology just to work around an issue that the tool should be
able to better handle.

Regards,

Austin
