What are the possible manufacturing issues and drawbacks involved in using a pad layout that is exactly the same dimensions as the <br>maximum tolerance of the footprint of the device being installed?&nbsp;&nbsp;Can I get away with having a 7% overhang of the interior &quot;heel&quot; of the surface mount part relative to the pad?&nbsp;&nbsp;Why should I follow an IPC recomended pad layout that takes up so much of my board space when the device will fit snug on a smaller layout?
 
You want to make sure that you have an adequate heel fillet (as well as toe fillet). Your main concern should be for the heel fillet.
