Abstract (en)

[origin: WO2018197314A1] The invention relates to a solder preform (11) for diffusion soldering. This consists of metal films (12), between which a paste (16) containing particles (15) is retained. The particles can consist of a soldering material, for example, while the films (12) consist of copper, for example. With the forming of the solder connection, intermetallic connections of the diffusion solder connection occur in a diffusion zone. The advantage of the use of a paste for producing the sandwich structure in the solder preform (11) lies in the fact that production is simplified and the paste (16) can guarantee a tolerance compensation to a certain extent. As well as the solder preform (11), the invention also relates to a method for producing a solder preform of this type, and a method for forming a diffusion solder connection with this solder preform.
