Hello, What methods are people using to measure line widths after etch on innerlayers. The copper weight can be 0.5 to 1 oz. The trace width can be 2 to 10 mils. The current method is too slow. An operator uses a video inspection system. He manually puts the piece on the table, lines it up and uses knobs to align reticules on a screen with the image. Is anyone using things like electrical tests, controlled impedance, TDR? What about laser edge detection systems? What kind of automation is available?
