Electrical connection element for contacting an electrically conductive structure on a substrate

A method for producing a pane with at least one electrical connection element, the method comprising:

• 1) producing an electrical connection element for electrical contacting of an electrically conductive structure on a substrate through the following steps:
• a) preparing two first solid subelements and a second solid subelement, wherein:
• i) the first and second subelements are made of different materials,
• ii) each of the two first subelements comprises a depression region on a soldering face of said subelement, and the second subelement comprises two foot regions and a bridging region arranged therebetween, and
• iii) the second subelement for connection to an electrical connection cable,
• b) arranging the second subelement atop each of the two first subelements, and
• c) connecting each of the two first subelements to the second subelement by means of a respective rivet that is guided through a hole that is formed in the depression region of each of the two first subelements;
• 2) applying a lead-free soldering compound on a contact surface of each of the two first subelements of the produced electrical connection element;
• 3) arranging the produced electrical connection element with the applied lead-free soldering compound on a region of an electrically conductive structure that is applied on a region of a substrate;
• and
• 4) connecting the produced electrical connection element to the electrically conductive structure under application of energy,
• wherein a difference between a coefficient of thermal expansion of the substrate and a coefficient of thermal expansion of each of the two first subelements is less than 5×10−6/° C.,
• wherein each of the two first subelements is arranged on an underside of a respective one of the two foot regions between the second subelement and the substrate, and
• wherein each of the two first subelements is implemented as a flat plate.
