Mutual alignment of film and circuit board for printing

摘要

To align a film (14) and a circuit board (20), before the circuit board is printed, at least two markings (16) are registered simultaneously with reference marks (22), by at least one camera (12).Also claimed is an assembly with at least two cameras (12) which can register optically the marking (16) on a film (14) in relation to a reference mark (22) on the circuit board (20). In the event that they do not coincide, a sliding mechanism corrects the circuit board (20) position in relation to the film within a tolerance range.
