While we're on that topic (or close anyway), what does the final barrel
size come to when you have a 20 mil pad (on all layers), 10 mil FHS, and
26 mil anti-pad? Is there a formula for figuring final barrel size?
Seems like I've seen one, but can't find it. Thanks in advance.

Hey guys,

 

We haven't thrown around anti-pads for a while!

 

What is the smallest anti-pad for an inner plane that you have
successfully used?

 

Has anyone used down to 5 mils a side anti-pad to pad?

 

Thanks,

Gary
