Embodiments disclosed herein include an electronic package. In an embodiment, the electronic package comprises a package substrate with a first surface and a second surface opposite from the first surface. In an embodiment, pads are on the first surface of the package substrate, where the pads have a first width. In an embodiment, a layer is on the first surface of the package substrate, where the layer comprises wells through the layer, and where the wells have a second width that is wider than the first width. In an embodiment, a liquid metal is in the wells and in contact with the pads.

An apparatus (1) for making contact with an electrical conductor (10, 20), in particular a cable conductor of a power supply cable, has a connecting body (4) that delimits a receiving space (6) into which the conductor (10, 20) with which contact is to be made can be inserted by way of its end. The apparatus (1) has a contact medium (30) with which electrical contact can be made with the end of the conductor (10, 20) under the action of a contact force. The contact medium (30) has a large number of electrically conductive contact bodies (32) introduced into the receiving space (6) and bearing against one another. At least some of the contact bodies can be brought into electrical contact-making contact with the ends of the conductors (10, 20).

Disclosed is a ground-connection apparatus for coolant-conducting components in motor vehicles. The ground-connection apparatus includes a coolant-conducting component and an electrically conductive ground connector. The coolant-conducting component includes a housing which is not or only poorly electrically conductive and comprises a passage opening for receiving an electrically conductive rivet element. The electrically conductive ground connector can be connected at a first end to a ground and comprises at a second end an opening for the rivet element, in particular a blind rivet. The rivet element along its longitudinal axis comprises a cooling liquid contact portion, a fastening portion, and a ground connection portion. A first end of the rivet element forms the cooling liquid contact portion, which is arranged within the housing in such a way that it can contact a cooling liquid located in the housing in order to establish an electrical connection with a cooling liquid. The fastening portion is, in regions, tangentially surrounded by the housing in the region of the passage opening. The ground connection portion is connected to the ground connector in such a way that an electrical connection is established between the ground connector and the housing rivet element, and the rivet element is connected by deformation to the housing in the region of the passage opening via the fastening portion.
