1. A method for producing a contact bump connection, said method comprising:

  • pressing a contact bump arranged on a first terminal face into a contact surface of a contact material of a second terminal face in a press-in direction,wherein pressing comprises driving the contact bump to penetrate into the contact material, said contact bump having a raised edge and at least one displacement pin in a displacement compartment being surrounded by the raised edge and being open towards a head end of the contact bump,wherein said pressing occurring in such a manner that, in the displacement compartment of the contact bump, while the raised edge and the displacement pin penetrate into the contact material of the second terminal face, in relation to the press-in direction, said contact material is exposed to pressure both by the raised edge radially inwardly and by the displacement pin radially outwardly,wherein the contact material moves into to the displacement compartment in response to the pressure exposure,wherein, in a first phase of producing the connection, the contact material of the second terminal face, in the displacement compartment of the contact bump, is exposed to pressure radially inwardly by the raised edge of the contact bump until reaching the free end of the connection pin, andwherein, in a second phase of producing the connection, when the contact bump continues to penetrate into the contact material of the second terminal face, the contact material is exposed to pressure radially inwardly by the raised edge and radially outwardly by the connection pin.
