Abstract:
A routing element for use with a multichip module. The routing element includes a substrate that carries conductive traces that provide either additional electrical paths or shorter electrical paths than those provided by a multichip module substrate. The conductive traces may be carried upon a single surface of the routing element substrate, internally by the routing element substrate, or include externally and internally carried portions. The routing element also includes a contact pad positioned at each end of each conductive trace thereof to facilitate electrical connection of each conductive trace to a corresponding terminal of the substrate or to a corresponding bond pad of a semiconductor device of the multichip module. Multichip modules are also disclosed, as are methods for designing the routing element and methods in which the routing element is used.
Abstract:
A circuit board assembly and method of fabricating an assembly are provided. The assembly preferably comprises a first circuit board defining an aperture and a second circuit board having an edge. The first circuit board has at least one conductive feature proximate the aperture, and the second circuit board has at least one conductive feature proximate the edge. Each board has at least one circuit trace in electrical communication with its respective conductive feature. The conductive features of the boards are placed in electrical communication with each other by way of the edge of the second board being disposed in the aperture of the first board. A solder joint can be disposed on the assembly so as to connect the first and second boards.
Abstract:
A time switch includes a circuit board equipped with a time switch circuit operated by a commercial power source, a battery board to which a back-up battery for supplying a back-up power to the circuit board in case of an interruption of a power supply from the commercial power source is mounted, and a casing in which the circuit board and the battery board are mounted. The battery board is a member separated from the circuit board, or integrally formed with the circuit board by way of an easy-to-break portion having a relatively weak mechanical strength. Thus, the battery board can be detached from the circuit board so that the back-up battery is disposed apart from the circuit board.
Abstract:
A mounting for a solderable component module (SCM.TM.) interconnect includes an elongated trench or blind via for receiving an edge of the module. The interconnect may be adjusted to reduce the parasitic inductance associated with the connection of the SCM interconnect and the motherboard. Preferably, the design of the finger connectors associated with the SCM interconnect or other board module can be adjusted to reduce parasitic inductance. Alternatively, the capacitance associated with the SCM interconnect or motherboard may be adjusted. The SCM interconnect preferably includes finger connectors which have a rectangular shape. The finger connectors preferably have a shape wherein the length is greater than the width and have an enhanced thickness which reduces parasitic inductance. The finger connectors are spaced close together.
Abstract:
A disk drive has an electrical interconnect for coupling one or more conductors provided on an actuator arm to a flexible connector. The interconnect consists of one or more tabs extending beyond a peripheral edge of the actuator arm and one or more slots formed on the flexible connector to receive the tabs. After the tabs are inserted into the corresponding slots, the tabs and flexible connector define L-shaped joints. Solder beads are deposited in these L-shaped joints to electrical couple the actuator arm to the flexible connector.

The present disclosure provides a power supply module used in a smart terminal and a power supply module assembly structure, the power supply module includes a substrate having first and second surfaces opposite to each other; a power passive element, an active element and a plurality of first conductive parts disposed at the substrate; the power passive element being independently disposed on the first surface of the substrate as a whole; wherein a maximum height of the power passive element disposed on the first surface of the substrate is greater than a sum of a maximum height of an element disposed on the second surface of the substrate and an half of the thickness of the substrate.
Abstract:
A mounting assembly for electro-mechanically connecting an electrically-powered device to a structure includes a housing, a first printed circuit board, an adapter, and a second printed circuit board. The housing has a shape defining a front opening and a first mating structure. The first printed circuit board is located within the housing and has a first plurality of electrical contacts facing the front opening. The adapter is attachable to the device and has a second mating structure that removably engages with the first mating structure of the housing. The second printed circuit board is coupled with the adapter and has a second plurality of electrical contacts exposed on its back surface to electrically connect to the first plurality of electrical contacts when the first mating structure of the housing engages with the second mating structure of the adapter.
Abstract:
An electrical connector for a circuit card assembly including a PCB includes a mating housing having a mating end movable relative to the PCB and contact modules coupled to the mating housing including signal contacts having a mating conductor, a mounting conductor and a flexible conductor. The flexible conductor is flexible to allow relative movement of the mating conductor relative to the mounting conductor. The flexible conductor has a bent portion changing shape. The contact modules have ground contacts providing electrical shielding for the signal contacts. The ground contacts include covers extending along and providing shielding along at least one side of the bent portion of the corresponding signal contact.
