Abstract: Electrical connection element having a first flat part made of a metallic substrate and a metallic contact layer applied to one surface of the substrate. A reliable coating is possible through the substrate being friction coated with the contact layer.

Abstract: The subject matter of the invention relates to a method for producing an electrical connection part, in which an electrical conductor (2) is provided, the electrical conductor (2) is electroplated and a contact area (4)of the conductor (2) is exposed by removing the electroplating (6). A method is to be specified with the subject matter of the invention which enables an electroplating (6) provided on the connection part (22) to be removed in a way which is particularly cost-effective and reliable. This is achieved according to the subject matter of the invention by removing the electroplating (6) in the contact area (4) using a beaming source (8).
