You should be aware, that an attempt to drill holes as you specified it very likely would break the drill tool. So the PCB manucturer has to filter it and replace it by a milling contour. You should check, which techniques are available at the manufacturer and prearrange if you should define either a placeholder drill tool or a milling contour in your CAD data.I provide multiple circular drills of size equal to width of pad drill at the same loaction with little offsets
I've just exparienced this problem. I have a board with a DC jack that throughole "blade" pins. I usualy do the layout and order board fab myself, but this time another guy did it for me. He specified something for the blade connectors. But instead of oval slots 4x1mm the manufacturer made oval pads on top and bottom with two holes at the ends of the pads.FvM said:The most important aspect is to make unequivocal production data and to avoid possible misunderstandings by the PCB manufacturer.
