Latest Patents
One of Bernd Leukel's latest patents is a method for manufacturing semiconductor power modules with an insulated design. This method involves presoldering a plurality of semiconductor sandwiches and a carrier unit that includes a metal base plate, ceramic insulating discs, and connecting tabs using a high-melting solder in the first step. In the second step, the semiconductor sandwiches and the carrier unit are joined together with a low-melting solder. Notably, both soldering steps are performed without flux in a gas environment consisting of hydrogen and forming gas, while preventing a mixture of the high-melting and low-melting solders during the second step.
Another significant patent is for a power transistor module. This module features a housing with a frame that forms the housing wall and a ceramic plate fastened to the frame, creating the housing bottom. The structured metallizations on the ceramic plate form conductor runs and terminal pads. The module includes components such as at least one power transistor and a bypass diode connected to the terminal pads. Additionally, wiring elements are connected to the components and are freely accessible from the top of the housing, including an auxiliary collector terminal and an auxiliary diode connected between the auxiliary collector terminal and the collector electrode of the power transistor.
