Abstract

A workpiece, designed as a printed circuit board for example, can be moved by means of a transport device under a laser unit in such a way that a region to be machined of the workpiece passes into the deflecting region of the laser beam. The workpiece is set between clamping jaws to a vertical position in which the laser beam is focused exactly on that surface of the workpiece which is to be machined. As a result, the machining accuracy can be considerably increased.
