John, After talking with the board house, I've decided to just plate the whole thing in hard gold. It turned out to be much cheaper than selectively plating one component. The only reason I hadn't planned to gold plate the whole thing was cost - wrong again! BTW for all who asked, the component is a six land circular pattern to mate with a gold POGO pin connector.

Is there a way to specify this? Bob You could probably specify this on a spare mechanical layer and add it to the top layer ident to make sure it gets noticed. On the print preview you could merge these layers (in colour) to give a graphical view of the where, why, when. The plating, is it going to be immersion or hard gold? Both will need masking of the rest of the board but because of the electrical requirements of hard gold you might need to add some way of coupling the nets together electrically (same idea as edge connector). Any reason the board cannot be completely immersion gold? (if this one part needs to be hard gold the anser does not matter as same issues apply).
