Bob: The process of putting two or more parts on one process panel is often referred to as "nesting". This is generally frowned upon, and can lead to more "nightmares" than those you alluded to (i.e., part number name, etc.). Here are a few that come to mind: * You will be hit with multiple tooling charges if some parts are ordered in higher quantities than others. The fabricator will have to tool up various panels with all parts on one panel, one part on others, etc. * You will be paying for dummy layers if the layer counts don't match up on all nested parts; the board house will have to fabricate the panel to the highest layer count. The same holds true for copper weights. * If there is a yield problem on one of the nested parts, all parts will have to be remade. This may add to cost, and somewhere along the line, price. If you decide to go the "nested" route, I would suggest that the nested parts be given one part number name. Most fab shops will need to track the product as one part number. Keep in mind all of the issues outlined above. I would recommend getting the parts quoted as both "nested" (you will need to supply a proposed array drawing) and individually. In this way you can make an enlightened decision as to whether nesting is worth it or not. Good luck!
