  • Patent number: 7541058
    Abstract: A circuitized substrate (e.g., PCB) including an internal optical pathway as part thereof such that the substrate is capable of transmitting and/or receiving both electrical and optical signals. The substrate includes an angular reflector on one of the cladding layers such that optical signals passing through the optical core will impinge on the angled reflecting surfaces of the angular reflector and be reflected up through an opening (including one with optically transparent material therein), e.g., to a second circuitized substrate also having at least one internal optical pathway as part thereof, to thus interconnect the two substrates optically. A method of making the substrate is also provided.

  • Publication number: 20090093073
    Abstract: A method of making a circuitized substrate (e.g., PCB) including at least one and possibly several internal optical pathways as part thereof such that the resulting substrate will be capable of transmitting and/or receiving both electrical and optical signals. The method involves forming at least one opening between a side of the optical core and an adjacent upstanding member such that the opening is defined by at least one angular sidewall. Light passing through the optical core material (or into the core from above) is reflected off this angular sidewall. The medium (e.g., air) within the opening thus also serves as a reflecting medium due to its own reflective index in comparison to that of the adjacent optical core material. The method utilizes many processes used in conventional PCB manufacturing, thereby keeping costs to a minimum.

  • Patent number: 7252515
    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.

  • Patent number: 7142121
    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.).

  • Publication number: 20060214010
    Abstract: A circuitized substrate in which selected ones of the signal conductors are substantially surrounded by shielding members which shield the conductors during passage of high frequency signals, e.g., to reduce noise. The shielding members may form solid members which lie parallel and/or perpendicular to the signal conductors, and may also be substantially cylindrical in shape to surround a conductive thru-hole which also forms part of the substrate. An electrical assembly and an information handling system are also defined.

  • Publication number: 20060180343
    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: 20060121722
    Abstract: A method of making a printed circuit board in which openings of different length are formed using a cover atop one of the openings to prevent dielectric material from an interim layer of heat-deformable dielectric material from entering the opening when the sub-composite having the opening therein is bonded to a second sub-composite. The bonded sub-composites are then provided with a second opening which extends there-through, this second opening being longer than the first. Pins of an electrical component may then be inserted within the first and second openings of different length.

  • Patent number: 6995322
    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.
