If you are expecting FR4 Fiberglass with 1oz copper foil, you aren't going to get it with this board. First it isn't FR4, but instead it is old school Phenolic. Then the copper is so thin on these boards the traces are really fragile. I have broken a few traces just from normal handling. I probably make 100 boards a year using my CNC, so I do know a bit about what I'm talking about. I would have sent these back, but unfortunately I couldn't wait for replacements, so I used them.
