To get the pull back on power layers we use Route keepout around
NP pins. This also serves the same function on signal layers to keep traces out
of the holes.

We put a pad but in the flash name we put “BLANK” and then it’s
not actually a pad on the board, just a pad for Allegro to use. Alternate would
be to put a route keepout around the pin.

To
All,
I’m
looking for alternative way of creating Non plated holes in allegro.
I
have 2 situations:
1)
Non
plated hole, No pad. – What are people using to keep traces away from the edge
of the drill hole?
2)
Non
plated hole with a pad. – In this case a donut shaped pad would be best where
one could specify an inside diameter and an external diameter.
I
have a current method, but am curious as to how other folks are doing either of
the above.
Thanks
Dave
