Temperature-stable composite of a stranded wire having a contact pad

A method for producing a connecting element on a contact surface, comprising:

• a. providing a stranded wire, a contact surface, and a sintering agent, b. coating at least a part of the stranded wire with sintering agent to obtain a coated stranded wire, c. positioning the coated stranded wire on the contact surface, d. exerting pressure on the coated stranded wire by means of a heated punch, thereby pressure sintering the coated stranded wire to the contact surface to produce a connecting element, wherein the heated punch comprises a depression with an opening, wherein the depression in the heated punch partially receives the coated stranded wire during the connection process, wherein the opening of the depression is larger than the diameter of the coated stranded wire so that the coated stranded wire is pressed onto the contact surface into the depression in the punch during pressure sintering, and wherein the aspect ratio of the connecting element of height (h) to width (b) is in the range of 0.5 to 3.
