A conductor assembly can include one or more conductors formed by a conductive material, and one or more filter cores formed integrally on and at least partially around the one or more conductors. The one or more filter cores can be formed of a material different than the conductive material and can be configured to reduce electromagnetic emissions from the one or more conductors.

A novel and useful system wiring apparatus and related techniques that address the

need to feed power and electronic signals to and from a sample board between the cold, low pressure region in a vacuum chamber and outside room temperature and atmospheric pressure. The wiring apparatus balances electrical resistance with the thermal conductivity of the power and signal conductors. Printed flexible cables are used having an annular sealing region which together with O-rings provide vacuum sealing while allowing electrical signals to pass between integrated circuit(s) inside the vacuum chamber and equipment outside the chamber. A thermal anchor is placed along the printed flexible cable to maintain a desired temperature along the cable. The printed flexible circuits are multilayer with two outer layers serving as an RF shield while two inner layers comprise the signal lines which typically require shielding, electrical isolation from each other and from external electromagnetic fields.

Disclosed is a method of manufacturing a transmission line using a nanostructured material. The method includes locating a first insulating layer above a first nanoflon layer including nanoflon, forming a first conductive layer above the first insulating layer, forming a first pattern, which transmits and receives a signal, by etching the first conductive layer, and locating a first ground layer below the first nanoflon layer. Here, the nanoflon is a nanostructured material formed by electrospinning a liquid resin at a high voltage.

An electronic device includes a circuit boards that have a same or substantially same shape, and flat cables that have a same or substantially same shape. The circuit boards are provided in a predetermined arrangement and are connected by the flat cables. Each of the flat cables is a semi-rigid cable, having a shape in accordance with the predetermined arrangement of the circuit boards.

A shielded electrical cable includes conductor sets extending along a length of the cable and spaced apart from each other along a width of the cable. First and second shielding films are disposed on opposite sides of the cable and include cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the films in combination substantially surround each conductor set. An adhesive layer bonds the shielding films together in the pinched portions of the cable. A transverse bending of the cable at a cable location of no more than 180 degrees over an inner radius of at most 2 mm causes a cable impedance of the selected insulated conductor proximate the cable location to vary by no more than 2 percent from an initial cable impedance measured at the cable location in an unbent configuration.

A shielded electrical ribbon cable includes adjacent first and second longitudinal conductor sets where each conductor set includes two or more insulated conductors. The first conductor set also includes a ground conductor that generally lies in the plane of the insulated conductors of the first conductor set. At least 90% of the periphery of each conductor set is encompassed by a shielding film. First and second non-conductive polymeric films are disposed on opposite sides of the cable and form cover portions substantially surrounding each conductor set, and pinched portions on each side of each conductor set. When the cable is laid flat, the distance between the center of the ground conductor of the first conductor set and the center of the nearest insulated conductor of the second conductor set is σ1, the center-to-center spacing of the insulated conductors of the second conductor set is σ2, and σ1/σ2 is greater than 0.7.

A shielded flat cable 1 includes one or more ground wires G1, the ground wires G1 being arrayed parallel to each other, one or more signal wires S1 and S2 arrayed parallel to the one or more ground wires G1, insulating layers 11 and 12 covering the one or more ground wires G1 and the signal wires S1 and S2, and shield layers 21 and 22 provided on outer surfaces of the insulating layers 11 and 12. In a cross-section of the one or more ground wires, the insulating layers 11 and 12 include openings 13 and 14 of which bottoms are respectively an upper surface and a lower surface of one ground wire G1, and the one ground wire G1 and the shield layers 21 and 22 are electrically coupled at the openings 13 and 14, and the signal wires S1 and S2 are surrounded by the one or more ground wires G1 and the shield layers 21 and 22.

A connecting object is used for connection to a device. The connecting object has a sheet-like shape. The device has at least two ground pins and at least one signal pin. The at least one signal pin is arranged between two of the ground pins in a pitch direction. The connecting object has a wiring layer, a shield layer and an insulator. The wiring layer is formed with only a signal line which is configured to be connected with the signal pin. The wiring layer is formed with no ground line which is configured to be connected with the ground pin. The shield layer covers the wiring layer via the insulator which is positioned between the shield layer and the wiring layer.

A flex flat cable structure includes metallic transmission lines having a power line and signal lines, first insulating jackets, a second insulating jacket, a third insulating jacket, and a shield layer. Each of the first insulating jackets encloses one of the metallic transmission lines. The second insulating jacket surrounds the first insulating jackets. The third insulating jacket encloses the first insulating jackets, and the second insulating jacket encloses the third insulating jacket. The shield layer is used to isolate the second insulating jacket from the third insulating jacket. The shield layer includes an insulating film, a first block layer, and a second block layer.

A ribbon cable includes a plurality of cable groups arranged side by side in a width direction of the ribbon cable and a wrapping film continuously wound on an outer side of the cable groups in a multi-turn wrapping manner at an inclined angle with respect to the width direction. There is a gap between every adjacent pair of cable groups.
