Abstract: An electronic power circuit includes several power modules (1) and is especially for controlling an electrical machine. Each power module (1) includes a plate-shaped integrated electronic circuit arrangement (2) having several electrical terminals. A perpendicular bent-over electrically conducting side leg (3) is arranged on each of two opposite-lying sides of the plate-shaped circuit arrangement (2). The side leg (3) forms an electrical contact and, in this way, the power module (1) has a U-shaped cross section. Each side leg (3) is provided with connecting elements via which two or several power modules (1) can be electrically and mechanically fixedly connected to each other while forming a mutual spacing between the plate-shaped circuit arrangement (2) via the side legs (3) for forming the electronic power circuit.

Abstract: The invention is a process to facilitate contacting of one or several power electronics components (10) with strip conductors (14, 15) on a substrate (12, 18) with the aid of a contact device (1) with several flat contact elements (6, 8) that are connected to each other by means of bridges (4, 5), including the following steps: (a) the contact device (1) is set on the upper side of the component (10); (b) the underside of a contact element (6, 8) is electrically connected both with a contact surface (S, G) on the upper side of a component (10) and with a strip conductor (14, 15); (c) at least one of the bridges (4, 5) between the individual contact elements (6, 8) is severed by means of thermal gouging. The invention also includes an assembly (16, 16′) produced with the process as well as a contact device (1) with several flat contact elements (6, 7) to facilitate contacting of power electronics components (10).

Abstract: Method of manufacturing a laser which is provided with a metal layer and a solder layer as early as in the wafer stage, and which is particularly suitable for so-called epi-down final mounting. An individual laser is obtained in that first a block comprising a row of lasers is formed from the wafer by cleaving, and subsequently the individual lasers are separated from the block. Strip-shaped openings are formed in the metal layer at the areas of end faces to be formed before the block is formed, and subsequently a score is provided in the surface of the semiconductor body in each opening in the longitudinal direction thereof, whereupon the solder layer is provided over the metal layer and over at least part of the openings therein, and the block is subsequently formed through cleaving at the areas of and in the direction of the scores.
