Abstract:
Buffer structures are provided that can be used to reduce a strain in a conformable electronic system that includes compliant components in electrical communication with more rigid device components. The buffer structures are disposed on, or at least partially embedded in, the conformable electronic system such that the buffer structures overlap with at least a portion of a junction region between a compliant component and a more rigid device component. The buffer structure can have a higher value of Young's modulus than an encapsulant of the conformable electronic system.

Abstract:
A method of connecting circuit boards capable of easily accomplishing the connection maintaining reliability. A method of connection comprising the steps of obtaining a laminated body of a first circuit board, an adhesive sheet and a second circuit board, and accomplishing electric conduction between the first circuit and the second circuit by applying heat and pressure to the laminated body of the first circuit board, the adhesive sheet and the second circuit board, wherein an end of the circuit formed on at least either the first circuit board or the second circuit board is terminated at a position separated away from an end of the substrate, and the adhesive of the adhesive sheet is partly arranged between the end of the substrate of the circuit board and the end of the circuit so as to be adhered to the opposing circuit board.
Abstract:
A jack with a flexible printed circuit board (FPC) is provided. The FPC is connected to the plug interface contacts and has a compensation circuit to compensate for near-end crosstalk (NEXT) and far-end crosstalk (FEXT). Capacitive and inductive compensation in the compensation circuit are of opposite polarity and are substantially equal in magnitude. The compensation circuit has a FEXT compensation zone containing compensation for the FEXT. Inductive and capacitive compensation in the FEXT compensation zone are distributed.
Abstract:
A communications jack assembly (200) includes: a jack frame (212) having a plug aperture (214); a dielectric mounting substrate attached to the jack frame; and a plurality of conductors (222a-228b) engaged with the mounting substrate, each of the conductors including a fixed end portion mounted with the mounting substrate and a free end portion extending into the plug aperture for electrical contact with a mating plug, each of the free end portions having substantially the same profile and being substantially transversely aligned in side-by-side relationship. A first pair of conductors (222) is sandwiched inside a second pair of conductors (226). The second pair of conductors includes a crossover (231), the positioning of crossover being selected to provide differential to common mode crosstalk compensation.
Abstract:
An apparatus and method for crosstalk compensation in a jack of a modular communications connector includes a flexible printed circuit board connected to jack contacts and to connections to a network cable. The flexible printed circuit board includes conductive traces arranged as one or more couplings to provide crosstalk compensation.
Abstract:
A connector is provided for simultaneously improving both the NEXT high frequency performance when low crosstalk plugs are used and the NEXT low frequency performance when high crosstalk plugs are used. The connector includes PCB substrates made of materials having different dielectric frequency characteristics.
