Abstract: The device is used for the mutual alignment of perforated printed circuit boards and pattern carriers, for example films. It consists of a support (10) with parallel pins (16) axially slidable and laterally immovable within guides disposed thereon. In order to achieve a very exact alignment of the printed circuit boards and the films in spite of unavoidable tolerances regarding the position and the diameter of the centering bores cooperating with the pins (16), the pins are substantially polygonal in cross-section, having parallel lateral surfaces with either chamfered or rounded corners. The corners of the pins taper from the support (10) toward their free ends. They furthermore can be retracted into the support (10) using an actuator to prevent the tilting of the printed circuit boards in the course of their removal.
