  • Patent number: 6981880
    Abstract: A method and apparatus for interconnecting an electronic module to a substrate through resilient wire conductors in an interposer arrangement. A carrier layer of insulating material with an array of apertures, arranged to align with both the electrical pads on an electronic module and electrical contacts on a substrate, each hold, for example, a resilient wadded wire connector. Each connector extends through the aperture provided and beyond the upper and lower surfaces of the carrier layer. Each resilient wadded wire connector and aperture is encapsulated with a elastomeric insulating material sufficiently deformable so as to allow said resilient wadded wire connector to deform upon application of a normal force from each side tending to depress the connector into its aperture. The encapsulation prevents loss or smear of a wadded wire connector when handling.

  • Publication number: 20050289019
    Abstract: A method and system for tracking goods, etc., food products, which involves identifying the received goods at a specified location and thereafter assigning an encoded readable code to each of the goods which can be only accessed by authorized personnel responsible for handling the goods on through to and including shipment, e.g., to customers. A host computer includes a database for encoding received identification data and thereafter encoding same to provide the readable codes. The method and system also allows the customer/recipient to access the codes to discern whether he/she has received the correct goods he purchased.

  • Patent number: 6974915
    Abstract: The details of a printed wiring board (PWB) sub-assembly and the method of producing the same are described. The sub-assembly comprises a printed circuit board electrically joined through a plurality of connections to one or more area array devices, such as modules or printed wiring boards. The sub-assembly can serve as a part of an original assembly. The sub-assembly can function as an after market item that can be readily substituted as a replacement for a failed component wherein the dimensional space between the printed circuit board and one or both of the area array devices must provide sufficient clearance for surface mounted devices.

  • Publication number: 20050270160
    Abstract: A radio frequency (RF) device (or “tag”) for containing specific information relating to a particular good being shipped from one location (e.g., warehouse) to another (e.g., customer). The device includes a circuitized substrate (e.g., a printed circuit board), a semiconductor chip, an antenna and a power regulator, and is designed in one embodiment to be partly inserted within a good (e.g., a cardboard box) containing one or more of the goods being shipped and tracked. Alternatively, the device may be attached by other means (e.g., adhesive). A shipper can simply track the goods containing such devices using wireless communication devices (e.g., satellites) to quickly and readily ascertain the specific location of the goods at any time as well as the appropriate desired information relating to such goods (e.g., quantity, weight, type, etc.).

  • Patent number: 6964884
    Abstract: A circuitized substrate in which three conductive layers (e.g., electroplated copper foil) are bonded (e.g., laminated) to two dielectric layers. Each of the foil surfaces which physically bond to a respective dielectric layer are smooth (e.g., preferably by chemical processing) and may include a thin, organic layer thereon. One of the conductive layers may function as a ground or voltage (power) plane while the other two may function as signal planes with a plurality of individual signal lines as part thereof. An electrical assembly and an information handling system utilizing such a circuitized substrate are also provided, as is a method of making the substrate.

  • Publication number: 20050039950
    Abstract: A circuitized substrate including a plurality of conductive and dielectric layers and also a plurality of conductive thru-holes therein for passing high speed signals, e.g., from one component to another mounted on the substrate. The substrate utilizes a signal routing pattern which uses the maximum length of each of the thru-holes wherever possible to thereby substantially eliminate signal loss (noise) due to thru-hole “stub” resonance. A multilayered circuitized substrate assembly using more than one circuitized substrate, an electrical assembly using a circuitized substrate and one or more electrical components, a method of making the circuitized substrate and an information handling system incorporating one or more circuitized substrate assemblies and attached components are also provided.

  • Patent number: 6848914
    Abstract: A structure and method for electrically coupling two substrates (e.g., a printed wiring board and an electronic module). Initially, a dielectric core is provided. A conductive wiring is helically wound circumferentially around the dielectric core. Additionally, a dielectric jacket may be formed around the conductive wiring. The resultant conductive rod structure is cut axially along the length of the conductive rod to generate conductive buttons having end contacts. The end contacts of the conductive buttons may be used to electrically couple the two substrates at corresponding pads of the two substrates.

  • Patent number: 6741778
    Abstract: Optical packages and a method of fabricating same, wherein an active optical device can be located relative to a substrate and coupler. The structure includes a substrate having electrical contact pads and alignment pads with precision aligned through-holes for at least one optical fiber. The optical fibers are supported by a housing, or coupler, having alignment pins that are precision located relative to the through-holes in the substrate and the optical fiber. A die, or active optical device, with one or more active optical elements on a first die surface and electrical contacts on a second die surface, is aligned with the electrical pads of the substrate and the active optical elements. The method incorporates the steps of grinding alignment pins into metallic pads and grinding optical fibers in one pass and then aligning the active optical device and the optical fibers by using the surface tension of conductive adhesive liquid. The fibers are then bonded.
