A method for attaching two electronics boards, e.g., a testing PCB and a space transformer, comprises rack welding resin prepreg and a mylar film to a testing PCB; laser drilling via holes in the resin prepreg and mylar film such that the holes are aligned on one side of the resin prepreg with connection/capture pads on the testing PCB and aligned (after attachment) on the other side of the resin prepreg with connection capture pads on a space transformer, filling the via holes with sintering paste; applying a pressure treatment to remove air, bubbles, and voids from the sintering paste; removing the mylar film; and using a lamination press cycle to attach a space transformer to the resin prepreg.

An apparatus may include a press-fit connection for a printed circuit board and a connecting element, where the connecting element is pressed into the printed circuit board in that the connecting element is tapered at the end facing the printed circuit board, and where an insertion depth to which the tapered section is inserted in the printed circuit board ensures a compensation for tolerances.

Example implementations relate to an electrical socket for an electronic packaging assembly, which accepts a modular integrated circuit (IC) on one side and a circuit board on another side. In some examples, the electrical socket has a first body mountable on a first surface of the circuit board and a second body mountable on a second surface of the circuit board. The first body includes a plurality of conductors (wire-terminated contacts), where each first conductor includes a first end to protrude beyond the first surface of the circuit board and a second end to protrude beyond the second surface of the circuit board. The second body includes a plurality of receptacles, where each receptacle is coupled to the second end of a respective first conductor.

An example apparatus includes a first printed circuit board (PCB) including: a first voltage phase circuit cluster; a second voltage phase circuit cluster; and a cluster of traces, the cluster of traces routed substantially perpendicular to the second voltage phase circuit cluster; a second PCB positioned below the first PCB; and a connector to connect the first PCB to the second PCB, the connector electrically coupled to the first voltage phase circuit cluster by the cluster of traces.

A power converter, for a vehicle that is at least partially electrically powered, has a first printed circuit board with DC link capacitors, a circuit breaker group for each alternating current phase, and terminals for alternating current busbars and direct current busbars. A second printed circuit board has a control apparatus for actuating the circuit breaker groups. Also, it has a respective signal pin carrier for the respective circuit breaker group. The signal pin carrier connects the first and the second printed circuit board. Thus, signals between the first and the second printed circuit board can be transmitted via the respective signal pin carrier. The signal pin carrier has six signal pins that are arranged on a plastic carrier.
