Abstract: The invention relates to a method for producing a power module, comprising: providing an insulating substrate, composed of a first metal layer, a second metal layer, and an insulating layer placed between the first metal layer and second metal layer; formation of numerous contact wires located on a first side of the insulating substrate facing away from the second metal layer and on a second side of the insulating substrate facing away from the first metal layer; applying an electrically conductive layer to the first side, which comes in contact with numerous power switches, and applying a heatsink to the second side.

Abstract: A method that makes it possible to produce actual cutting contours on tubes with only rough tolerances, to which contours others of the tubes can be joined and welded, wherein, as a result of the actual cutting contours being modified, the rough shape tolerance of the tubes does not enter the tolerance chain, or enters the latter only a little, for the tubes to be fully welded to form a tubular frame. It also allows the automated reception of only pre-oriented tubes by a gripping arm and the infeed thereof to a laser cutting device.

Abstract: A method for trimming a bent tube along an actual cutting contour, wherein a virtual tolerance envelope is calculated for the tube and a laser beam cutting the actual cutting contour is guided along a desired cutting contour related to the tolerance envelope, wherein the actual cutting contour is produced as a projection of the desired cutting contour or the laser beam is guided along the corrected desired cutting contour, which then corresponds to the actual cutting contour.

Abstract: Optical or optoelectronic array with an assembly holder and an optical or optoelectronic assembly located on it to position the assembly holder on an assembly surface of an optical bench in a way that is movable only in a first plane of adjustment parallel to the assembly surfacewhere the assembly holder has an assembly base for positioning the assembly holder on the assembly surface as well as a seat which is open the entire distance from one outside surface of the assembly holder to the opposite outside surface of the assembly holder in which the optical or optoelectronic assembly is located and which is formed in such a way that the optical or optoelectronic assembly can be moved relative to the assembly holder only in a second plane of adjustment which is non-parallel to the first plane of adjustment, extending parallel to the directional passage of the seat.
