Latest Patents

One of Klaus Bunk's latest patents is a semiconductor power module that includes a substrate formed of metallized ceramic. This innovative module features at least one semiconductor power component with a base surface soldered to the metallized ceramic. Additionally, it incorporates at least one heat conduit integrated into the module, which includes a condensation area that has a larger surface than the base surface. This design allows for effective distribution of dissipation heat from the semiconductor power component.

Another significant patent is a method for manufacturing insulated semiconductor power modules. This method involves presoldering a plurality of semiconductor sandwiches and a carrier unit, which includes a metal base plate, ceramic insulating discs, and connecting tabs with a high-melting solder in a first step. In a second step, the semiconductor sandwiches and the carrier unit are joined together using a low-melting solder. Notably, both soldering steps are performed without flux in a gas from the group consisting of hydrogen and forming gas, while preventing a mixture of the high-melting solder and the low-melting solder during the second step.
