Abstract:
1. A method for controlling a manufacturing process of a printed circuit board, the method comprising: calculating at least one layer misalignment between layers of the printed circuit board that are expected to be mutually aligned; wherein the layers are manufactured by at least a direct imaging device that exposes a photo-resistive material to radiation to provide a pattern; wherein the calculating is responsive to at least one image acquired by an automatic optical inspection tool; selecting, if the at least one layer misalignment does not exceed the at least one allowable misalignment threshold, a first selected response that comprises manufacturing at least one additional layer of the printed circuit board; and selecting a second selected response out of a plurality of responses, if the at least one layer misalignment exceeds the at least one allowable misalignment threshold; wherein the selecting of the second selected response is responsive to a cost of an execution of response of each of the plurality of responses.
