    • A method for applying multiple discrete layer fragments made of dried metal sintering compound onto predetermined, electrically-conductive surface areas of a carrier for electronic components, comprising the steps: (1) application of multiple discrete layer fragments made of metal sintering compound on one side of a flat transfer substrate in mirrored arrangement to the predetermined, electrically-conductive surface areas, (2) drying of the metal sintering compound thus applied while preventing sintering, (3) arranging and contacting of the transfer substrate with the layer fragments made of dried metal sintering compound facing toward the surface of the carrier for electronic components and while guaranteeing a congruent positioning of the surface area of the transfer substrate provided with the dried metal sintering compound and the predetermined, electrically-conductive surface area of the carrier for electronic components, (4) application of pressing force on the contact arrangement created in Step (3), and (5) removal of the transfer substrate from the contact arrangement, wherein the adhesive force of the dried metal sintering compound following the completion of Step (4) is greater with respect to the predetermined, electrically-conductive surface areas of the carrier for electronic components than with respect to the surface of the transfer substrate, wherein the flat transfer substrate is a non-sinterable and, if necessary, coated metal film or a thermoplastic plastic film, wherein the carrier for electronic components describes a substrate with a flat surface having one or more indentations from 10 to 500 μm and at the same time is selected from the group consisting of pressed screens, ceramic substrates, DCB substrates, and metal composite materials, and wherein at least one predetermined, electrically-conductive surface area is located in an indentation. The carrier for electronic components can already be populated with one or more electronic components. The carrier substrate can have recesses for electronic components already present on the carrier. The carrier for electronic components provided with dried metal sintering compound is used in a method, in which initially a sandwich arrangement is created from the carrier for electronic components provided with dried metal sintering compound and the electronic components, and the sandwich arrangement is subsequently subjected to a sintering process.
