--001a11c39e7287f7df052dcb062a Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable What about using a through hole jumper to perform the same function as the zero ohm SMD when the planes are on the surface? Assuming you have some freedom to place the cross connect anywhere along their boarder you should be able to find two spots for the through holes. I don't know if that would change the cost of manufacturing an otherwise all SMD board with only layer to layer vias, but I would think the process for making a top to bottom via would also make plated through holes. I just know that setting up something I just HAVE to do on the very last run before submitting is a surefire recipe for disaster for me. I would rather put up with seeing the short every time I rand DRC than risk sending the files off to hastily.
