Boardhouse: Not to be confruntational, just trying to better understand what you're telling us. When you say, "Standard spacing most board houses would like to see is" blablabla. * What are the units of these dimensions? * You'd like to see these dim

Hi Richard, I assume that you deal with a component that has 20mil pitch. In this case depending on your pad design you get from 8 to 10mil spacing for your apertures. With a slight reduction of the aperture (10 to 15% for avoiding shorts)and a 6mil
