The question of, "do we consider the aspect ratio to be from the plated hole or the drilled hole?" I called my vendor, Holaday Circuits Inc. and asked the question fully expecting the answer, "from the nominal plated hole", to my surprise it was the opposite! My sales engineer said that they look at the aspect ratio to the drilled hole! Yeppieee! we have more room!
