Abstract: A method and an apparatus for the pressure-sintering connection of a first and a second connection provide a frame element lowerable onto a frame surface surrounding the supporting surface, having a sintering ram lowerable lowered from the normal direction onto the second connection partner and exerts pressure thereon, and converting a sintering paste between the connection partners into a sintered metal, and having an auxiliary apparatus for the arrangement of a separating film for the peripheral covering of the frame surface and the connection partners. This arrangement of the separating film produces an inner region bounded by the frame element and bounded by a separating film portion within the frame element and by the supporting surface, and injection opening and an outlet opening allow a second gas to flush through said inner region from the injection opening to the outlet opening and displace a first gas.

Abstract: A method and a device for pressure sintering connection of a joining group composed of a first and a second joining partner by means of a device with a lower tool and an upper tool having the steps: providing the joining group at room temperature as an initial temperature, arranging the joining group between the supporting surface and the pressure surface, wherein the joining group has no direct thermal contact with the supporting surface and no direct thermal contact with the pressure surface, introducing pressure onto the joining group, wherein at the start of the introduction of pressure the starting temperature of the joining group is no more than 100K above an initial temperature; increasing the temperature of the sintering agent by at least 50K above the starting temperature; ending the introduction of pressure.
