A composite assembly of three stacked joining partners, and a corresponding method. The three stacked joining partners are materially bonded to one another by an upper solder layer and a lower solder layer. An upper joining partner and a lower joining partner are fixed in their height and have a specified distance from one another. The upper solder layer is fashioned from a first solder agent, having a first melt temperature, between the upper joining partner and a middle joining partner. The second solder layer is fashioned from a second solder agent, having a higher, second melt temperature, between the middle joining partner and the lower joining partner. The upper joining partner has an upwardly open solder compensating opening filled with the first solder agent, from which, to fill the gap between the upper joining partner and the middle joining partner, the first solder agent subsequently flows into the gap.
