Abstract:
An easily bendable high-frequency signal transmission line includes a dielectric body including a protection layer and dielectric sheets laminated on each other, a surface and an undersurface. A signal line is a linear conductor disposed in the dielectric body. A ground conductor is disposed in the dielectric body, faces the signal line via the dielectric sheet, and continuously extends along the signal line. A ground conductor is disposed in the dielectric body, faces the ground conductor via the signal line sandwiched therebetween, and includes a plurality of openings arranged along the signal line. The surface of the dielectric body on the side of the ground conductor with respect to the signal line is in contact with a battery pack.
Abstract:
A connection substrate 13 includes a base material 130 formed by stacking a plurality of dielectric layers 130a to 130f and a plurality of through conductors 20 provided penetrating through the dielectric layers 130c to 130f adjacent to each other. A plurality of radiation shielding films 21a to 23a formed integrally with each of the plurality of through conductors 20 and separated from each other are provided at two or more interlayer parts in the dielectric layers 130c to 130f. A region PR1 of the radiation shielding film 21a (21b) formed integrally with one through conductor 20 in one interlayer part projected onto a virtual plane normal to a predetermined direction and a region of the radiation shielding film 22b or 22c (22c) formed integrally with another through conductor 20 in another interlayer part projected onto the virtual plane do not overlap each other. Accordingly, the readout circuits of an integrated circuit device can be protected from radiation, and an increase in parasitic capacitance can be suppressed.

Abstract:
Described herein are electronic assemblies including a subassembly film and methods for making the same. In some embodiments, a first subassembly is formed by placing an electronic die at a die placement location on a subassembly film. A second subassembly may be formed by placing the first subassembly at a subassembly placement position on a base layer, such that electrical contacts/traces on the first film overlap with electrical contacts/traces at a subassembly connection point on the base layer. Placement of the die on the subassembly film may be performed with automatic placement machinery that has a placement accuracy that is greater than that required to place the first subassembly on the base layer. As a result, the costly and time consuming manual inspection of die placement may be avoided.
Abstract:
A paddle card construction disclosed for use in connecting electronic devices together. The paddle card takes the form of a circuit board that has a plurality of conductive contact pads arranged thereon in pairs. The contact pads of each pair are spaced apart from each other to provide a pair of points to which cable wire free ends may be terminated, such as by soldering. The spacing of the pads apart from each other in effect reduces to amount of capacitance in the cable wire termination area on the circuit board, thereby reducing the impedance and insertion loss in that area at high frequencies. The contact pads of each pair may be further interconnected together by a thin, conductive trace that extends lengthwise between the contact pads.

An electronic control device includes a substrate, a plurality of component-mounted wires disposed on the substrate, a plurality of electronic components mounted on the respective component-mounted wires, a common wire disposed on the substrate and coupled with each of the electronic components, an interrupt wire coupled between one of the component-mounted wires and the common wire, a connection wire via which the interrupt wire is coupled with one of the common wire and the one of the component-mounted wires, and a solder disposed between each of the electronic components and a corresponding one of the component-mounted wires and having a lower melting point than the interrupt wire. The interrupt wire is configured to melt in accordance with heat generated by an overcurrent so as to interrupt a coupling between the one of the component-mounted wires and the common wire.

A capacitance is created between the first ground conductor and each of the floating conductors, and has a greater value than a capacitance created between the signal line and the floating conductor.
