If you happen to work with larger voltages, you need isolated gaps on the PCB. I would do that by drawing a filled polygon on the bottom layer, or a group of overlapping or conntected wires, as if the isolation were a wire. | If you happen to work with larger voltages, you need isolated gaps on the PCB.

After the milling, I would use a sharp knive to lift the copper from the board at a corner, and peel it off. If you know the trick, it works quite well. | After the milling, I would use a sharp knive to lift the copper from the board at a corner, and peel it off.

[[Datei:peeledpcb.png|600 px|A peeled off PCB. Ok that not for isolation. You see here that I needed to peel off multiple areas. If I had connected the individual regions with overlapping wires, I could have saved some time.]] | [[Datei:peeledpcb.png|600 px|A peeled off PCB. Ok that not for isolation.
