How feasible is it to edge plate a PCB or at least a portion of one? I've seen it done but as I understand the outer edge is only cut after plating at most fab houses. Is this something that's commonly possible? I'm currently working on a board that would benefit from this as it slides into a metallic case and needs to be connected to it.
Answer
If you mean solid edge plating (rather than castellations) then it's certainly possible, but you will have to ask your PCB house if they can do it. As far as I am aware it's not too hard to do, it's just not such a common requirement (good for EMC behaviour)
