METHOD FOR GENERATING AT LEAST ONE THROUGH-HOLE AND DEVICE FOR CARRYING OUT SUCH A METHOD

摘要

The invention relates to a method for generating at least one through-hole (3, 4) in a wall of a workpiece (2) bounding a hollow space (12) of the workpiece (2), said method using a laser beam (7) directed onto the wall (9) from the exterior. A paste-like protective agent (13) is thereby introduced into the hollow space of the workpiece (2). The paste-like protective agent (13) is applied in an extension (10) of the laser beam (7) guided through the through-hole (3) in front of a rear wall bounding the hollow space (12). Reliable protection of the rear wall (11) during laser drilling of the through-hole (3) is thereby ensured.
