Abstract: A method of separating a workpiece into a plurality of sections includes generating one or a plurality of lines of modified material along one or a plurality of predefined separating lines in the workpiece in a first step by local material processing using a laser beam through a surface of the workpiece, which results in a reduction of breaking stress of the workpiece along the separating lines, and dividing, in a second step, the workpiece into the sections along the separating lines by thermal laser beam separation, wherein the one or the plurality of lines are generated completely or at least in portions at a distance from the surface in the workpiece.

Abstract: A method of producing a multilayer element with a substrate and at least one conductor structure connected in an areal manner to the substrate, which has first regions of electrically conductive material present in accordance with a prescribed pattern, electrically non-conductive second regions lying between the first regions to produce RFID antennas or flexible printed circuit boards in a roller-to-roller process, the method including connecting a conductor foil to the substrate by a laterally structured layer of adhesive lying in between such that in first regions a partial bonding contact between the substrate and the conductor foil is created at a multiplicity of bonding zones, and in laterally extended second regions the conductor foil is not connected or is connected less firmly by adhesive to the substrate; structuring the conductor foil by cutting the conductor foil along boundaries of the first regions; and removing contiguous pieces of foil of the conductor foil from laterally extended second region
