        Motorola's application note AN1231 puts forth the best
        attempt at a method I've seen yet.  It suggests that
        the attach pad on the PWB should match the attach pad
        on the bottom of the device.  Seems pretty logical to
        me, but the problem then becomes that device vendors
        do not always include this dimension.....
