A wiring board has a metal-made base having a front surface and a back surface, an insulating frame body bonded to the front surface of the base through a bonding layer made of bonding material, a mounting area where a component is supposed to be mounted on the front surface of the base, and a restriction portion formed by a groove or a protrusion that is provided on the front surface of the base or by a combination of the groove and the protrusion. The restriction portion is arranged in at least a part of an area between the mounting area and the frame body on the front surface in plan view.

Electromagnetic interference (EMI) shields having attenuation interfaces are disclosed. A disclosed example EMI shield includes side walls defining sides of the EMI shield, and an attenuation interface to be placed into contact with a circuit board. The attenuation interface includes an inner perimeter having an EMI absorber and an outer perimeter having a metal backing to at least partially surround the EMI absorber.

A circuit board assembly is provided and includes a first circuit board, a second circuit board and a first connecting module. The first connecting module includes a first connecting wire, a first connector and a second connector. The first circuit board includes a first processor, and the second circuit board includes a second processor. One end of the first connector is connected to one end of the first connecting wire, and the other end of the first connector is connected to the first circuit board. One end of the second connector is connected to the other end of the first connecting wire, and the other end of the second connector is connected to the second circuit board. The first connector is adjacent to the first processor, and the second connector is adjacent to the second processor.

A computing system is provided. The computing system includes a semi-flexible printed circuit board assembly (PCBA) with a first element and a second element. The first element is configured to move in a non-planar direction with respect to the second element. The computing system also includes an internal trace connecting the first element and the second element of the semi-flexible PCBA. The computing system also includes a support mechanism, which is configured to constrain relative movements between the first element with respect to the second element of the semi-flexible PCBA.

A vehicle steering wheel assembly includes a steering wheel frame having a rim portion and a hub portion within the rim portion. The hub has a first surface facing a rear of the vehicle and a second surface facing a front of the vehicle. An electronic control unit (ECU) has a first surface facing the rear of the vehicle located in a plane that is disposed between a second plane that includes the second surface of the hub and the front of the vehicle. An electrical connector extends from the first surface of the ECU towards the first surface of the hub portion. The ECU comprises a clock spring connector electrically coupled to the electrical connector via a wire trace. By incorporating wire traces that provide electrical connections between the electrical connectors and the clock spring connector, the ECU reduces the size and/or number of wire harnesses used in the steering wheel assembly.

An apparatus for combining PCBs may include a pick-up mechanism, a gripping mechanism and a combining mechanism. The pick-up mechanism may pick-up the PCBs connected with each other by a flexible connection member. The gripping mechanism may grip a frame. The combining mechanism may press the flexible connection member using the frame to combine the PCBs with the frame. The process for combining the PCBs with the frame may be automatically performed so that a time for combining the PCBs with the frame is reduced and errors related to the combining process are decreased.

A method for fabricating an assemble substrate is provided, including stacking a circuit portion on a plurality of circuit members. The circuit members are spaced apart from one another in a current packaging process to increase a layer area. The assemble substrate thus fabricated meets the requirements for a packaging substrate of a large size, and has a high yield and low fabrication cost.

An electronic device and associated methods are disclosed. In one example, the electronic device includes a first rigid substrate, a second rigid substrate, a flexible substrate comprising a first portion attached to the first rigid substrate, a second portion attached to the second rigid substrate, a middle portion connecting the first portion to the second portion, wherein the middle portion is bent, and metallic traces therethrough, and a component forming a direct interface with the middle portion of the flexible substrate, the component electrically coupled to the metallic traces. In selected examples, the device further includes a casing.

A power-electronic metal-ceramic module (10) comprising a metal-ceramic substrate (12) made of a ceramic carrier (14) having a metal top and bottom ply (16, 18), which is joined on or in the metal top ply (16) and/or the metal bottom ply (18) with a metal layer (16, 18, 22, 23) forming a frame (24) for accommodating at least one electronic component (30) and at least one electronic component (30) accommodated in the frame (24).

A method includes preparing a circuit board that includes a first metal pattern over a first face side of the substrate, a first electrode in a periphery of the first metal pattern, a second electrode over a second face side of the substrate, and a second metal pattern thermally connected to the first metal pattern and in which an electronic device is fixed on the first metal pattern and an electronic component is electrically connected to the second electrode, and connecting the first electrode and a third electrode of the electronic device by a bonding wire with the electronic device being heated. By a board support stage, the electronic device is heated by transferring heat to the electronic device via the second and then first metal pattern with the circuit board being supported to form a space including the electronic component between the second face and the board support stage.
