Not only is this unnecessary in that the thermal drop of the
escape etch of the SMT pad should be the same or better
than four spokes, but inductance to the power plane is
increased and the power plane is chopped up, especially
in high density BGA areas where you need it the most.
If you have a report that shows this, or think that I am off
my rocker, please post as I imagine that many folks reading
this may be in a similar situation.
The bounds of Time, Space or Mechanics should never stand
in the way of a perfectly good idea.......
The time is gone, The email's over, thought I'd
something more to say.........
