Hello, I have not seen any example of via-in-pad and via-on-pad yet. So I am not sure if I can determine which one is via-on-pad and the other is via-in-pad because I can not imagine. Do they have differences because of design, manufacture, or assemly?

It is just a naming thing. If the via is on a pad, it's in it. I love 'em because they reduce layers and open up channels for routing signals. Any questions, don't hesitate to email me. I can send you screen shots of notes and stackups. Best regards, Bob Wilson, CID http://www.cstone-design.com/home.html > > 1.
