Circuit board linewidth measuring instrument

Circuit board linewidth measuring instrumentTesting principle:

Using a light source to illuminate the circuit board under test, the image signal is transmitted to the computer through optical amplification and CCD photoelectric signal conversion, displaying a clear image on the interface. Then, the measurement area of the image is directly selected with the mouse for edge detection and returning the measurement result.
