Embodiments of the present disclosure are directed towards techniques and configurations for layered interconnect structures for bridge interconnection in integrated circuit assemblies. In one embodiment, an apparatus may include a substrate and a bridge embedded in the substrate. The bridge may be configured to route electrical signals between two dies. An interconnect structure, electrically coupled with the bridge, may include a via structure including a first conductive material, a barrier layer including a second conductive material disposed on the via structure, and a solderable material including a third conductive material disposed on the barrier layer. The first conductive material, the second conductive material, and the third conductive material may have different chemical composition. Other embodiments may be described and/or claimed.

A jumper may be adapted to transmit an electrical signal. The jumper may be included in a system on a chip. The system on a chip may include a substrate, and the substrate may include one or more routing layers. The jumper may be included in the one or more routing layers of the substrate. A first interconnect may be positioned on a first side of the system on a chip, and a second interconnect may be positioned on a second side of the system on a chip. The jumper may be in electrical communication with the first interconnect, and may be in electrical communication with the second interconnect. The jumper may be electrically isolated from other components of the system on a chip, such as one or more die coupled to the substrate.

A metal core board assembly can include a metal base layer upon which at least one electrical component is disposed. The metal core board assembly can also include a circuit assembly disposed proximate to the metal base layer, where the circuit assembly is isolated from the metal base layer, where the circuit assembly is electrically coupled to the at least one electrical component. Separating the circuit assembly from the metal base layer can reduce effects of capacitive coupling on the circuit assembly.

A motor driving device that converts alternating-current power to direct-current power and drives a motor, the motor driving device including a printed circuit board having a first plate surface and a second plate surface, having an inverter module and an inverter module provided on the first plate surface, having a first power pattern provided on the second plate surface and connected to the inverter module, having a second power pattern provided on the second plate surface and connected to the inverter module, and having a jumper portion to connect the first power pattern and the second power pattern. A cross-sectional area of the jumper portion is larger than a cross-sectional area of the first power pattern or the second power pattern.

A power module includes a number of sub-modules connected via removable jumpers. The removable jumpers allow the connections between one or more power semiconductor die in the sub-modules to be reconfigured, such that when the removable jumpers are provided, the power module has a first function, and when the removable jumpers are removed, the power module has a second function. The removable jumpers may also allow for independent testing of the sub-modules. The power module may also include a multi-layer printed circuit board (PCB), which is used to connect one or more contacts of the power semiconductor die. The multi-layer PCB reduces stray inductance between the contacts and therefore improves the performance of the power module.

A printed circuit board (1) comprises a conductive outer layer (2) and at least one conductive inner layer (4, 14). At least one bus bar (7, 8) for conducting high current and at least one power semiconductor (12) for controlling and/or activating the high current are disposed on a side of the outer layer (2) facing away from the at least one inner layer (4, 14). The printed circuit board (1) allows for a high level of component density while simultaneously providing for effective heat dissipation. Furthermore, the printed circuit board (1) can be produced economically and flexibly.

A compact solid state relay (7) is provided. Solid state devices (74, 75), such as Triacs or Thyristors are used to implement the relay functionality. The device is at least partially enclosed in a housing that has pins for mounting on an electronics board. A number of U shaped jumpers (72) or other jumpers or wires are provided in the housing to act as heat sinks. A sub-miniature fan (70) is positioned to create an air flow over the heat sinks and dissipate heat from the device.

A wireless relay may include a housing; an output, disposed within the housing; and a wireless interface, disposed within the housing, wherein the wireless interface is to receive wireless communication signals including settings to configure one or more functionalities associated with the wireless relay.

A circuit assembly 1 includes a semiconductor switching element, a main substrate, a plurality of bus bars and a sub-substrate that are overlaid on the main substrate, and a jumper wire. The main substrate includes a first insulating substrate and a first conductive path. The sub-substrate includes a second insulating substrate and a second conductive path, and is overlaid on the main substrate and arranged in the same layer as the bus bars. The jumper wire connects the first conductive path with the second conductive path. A plurality of terminals of the semiconductor switching element include a drain terminal 42 and a source terminal that are connected to the bus bar and a gate terminal connected to the second conductive path. A noise reduction element is mounted on the sub-substrate.

A battery bridge for an electronic device, preferably for an electronic implant, has an electrically conductive first contact element, an electrically conductive second contact element and an insulator. The first contact element and the second contact element comprise a weldable material. In a first state of the battery bridge, the first contact element is distanced from the second contact element via a predefined air gap and the first contact element is electrically insulated from the second contact element by the air gap and the insulator. The battery bridge is formed in such a way that it can be transferred, by welding the first contact element and the second contact element together, into a second state, in which the air gap between the first contact element and the second contact element is closed electrically conductively, at least in part. A method for activating such an electronic device is also disclosed.
