Very often, you would like to fit multiple designs onto a board order. These are designs that you will cut apart yourself – the manufacturer does not need to cut a V-groove or drill a row of holes or cut a slot. Some manufacturers will allow this without charging extra, some will charge extra, and some will not allow it at all.
PCBShopper now lets you specify whether you will have multiple designs on the board, and will factor that into the price results. We can’t overemphasize this: the feature applies only to multiple designs that require no extra effort on the manufacturer’s part. If you want your designs separated by grooves, etc., that is another feature that PCBShopper does not, as yet, support.
