Abstract:
A multilayer circuit board assembly includes one or more radio frequency (RF) interconnects between different circuit layers on different circuit boards which make up the circuit board assembly. The RF interconnects can include one or more RF matching pads which provide a mechanism for matching impedance characteristics of RF stubs to provide the RF interconnects having desired insertion loss and impedance characteristics over a desired RF operating frequency band. The RF matching pads allow the manufacture of circuit boards having RF interconnects without the need to perform any back drill and back fill operation to remove stub portions of the RF interconnects in the multilayer circuit board assembly.
Abstract:
A flexible circuit has a roll-molded thermoplastic resin base sheet with an integrally molded mounting structure located to receive a light emitting diode device in an illuminating position. The mounting structure is a pin receptacle constructed to receive a pin of the light emitting diode device. An electrically conductive portion is carried by the resin base and positioned for electric connection to conductors of the device. Another flexible circuit carries discrete integrated circuit chips and a field of fastener elements extending from a surface of a resin strip carrying conductive traces interconnecting the chips.

Abstract:
The present invention relates to a socket for electronic component which contains an electronic component. The socket for electronic component comprises a platy base, containers formed to be concaved on a front face of the base and to contain LED packages therein, connectors provided on side faces and connected to other members, supports each of which supports and fixes the LED package contained in the container and electrically connected to the LED package, heat conductors each of which is provided continuously from a bottom face side of the container to a rear face of the base and contacts the LED package contained in the container so as to conduct heat generated by the LED package, and terminals electrically connected to the other members coupled with the connectors and the supports. The heat generated by the LED package is conducted to the rear face of the base through the heat conductors, and effectively radiated to an installation member on which the socket for electronic component is mounted.
Abstract:
An electrical connector includes a first connector body having an interlocking feature extending therefrom. The interlocking feature interlocks the first connector body with a complimentary interlocking feature extending from an adjacent second connector body to distribute a lateral force on either the first or second connector bodies across the adjacent connector body thereby reducing a rotational moment at a base of each electrical connector connected to a printed circuit board (PCB).
Abstract:
A method and structure is disclosed for forming a removable interconnect for semiconductor packages, where the connector is adapted to repeatedly change from a first shape into a second shape upon being subjected to a temperature change and to repeatedly return to the first shape when not being subjected to the temperature change. The connector can be disconnected when the connector is in its second shape and the connector cannot be disconnected when the connector is in its first shape.
