No, I have no need for traces that fine, but now that I have a stable"platform" I want to test the limits. Once I get the MCUversion online I am going to work on double sided boards.

- 1 - All 5 mm traces are intact.
- 2 - 5 mil traces/10 mil spaces works perfectly - no shorts, no open
- traces, no "near misses".
- 3 - 5/5 does not. The traces are intact but they spread into the
- spaces and short together in many areas. The obvious conclusion is
- that the traces are wider than 5 mil.
- One solution might be to make the traces even thinner so if they
- spread it won't obliterate the spaces.
- What I need is a good way to measure the thicknesses. I do have a
- stage micrometer for my microscope, but I really would like a USB
- microscope with software to measure. Does anyone have asuggestion?
- I could also use a test pattern that has a variety of traces/spaces.
- Does anyone have one in some common format?
- Thanks for your encouragement and suggestions.
