METHOD FOR WELDING WITHOUT FILLER MATERIAL AND ELECTRONIC POWER MODULE PRODUCED BY THIS METHOD

摘要

The method according to the invention concerns welding without filler material in order to link together first and second elements (3, 4) made from metal materials, and involves bringing a welding part (8) of the second element (4) linked by a fold (11) to a support part (9) of the second element (4) into contact with the first element (3), and directing a laser beam (7) on the welding part in such a way as to cause the materials to melt locally. In the present application, the first element (3) is a conductive track of a power module (1) formed on a flat substrate (2, 3), the second element (4) is a connection terminal of the power module (1), and the laser beam (7) is directed on the welding part perpendicularly to the substrate (2, 3).
