Abstract: A system for making flexible circuit films includes an inelastic conveyor, a web handling apparatus configured to pass a flexible substrate around the inelastic conveyor, an image acquisition apparatus configured to measure positions of a first set of alignment marks on the flexible substrate at a first conveyor location, an exposure apparatus configured to patternwise expose a photosensitive material on the flexible substrate at a second conveyor location, and an image processor configured to receive the measured positions of the first set of alignment marks, and to compare the measured positions with reference positions of the first set of alignment marks. The exposure apparatus is configured to patternwise expose the photosensitive material based on the comparison between the measured positions and the reference positions.

Abstract: Approaches for enhancing web position determination involve phase locking a web movement encoder signal to a sensed web fiducial signal. Fiducials disposed along a longitudinal axis of a substrate are sensed and corresponding sensor signals are generated. An estimated web position is provided by one or more encoder signals. The phase difference between the sensor signals and the encoder signals is calculated and the web position error is determined based on the phase difference. The web position error signal can be fed back to adjust the encoder signals which improves the accuracy of the web position determination.
