  • Patent number: 7499287
    Abstract: A structural printed wiring board panel includes a multilayer printed wiring board having opposing, outer faces and interlayer interconnects that route RF, power and control signals. Connection areas are formed in or on at least on one face for connecting the interlayer interconnects and any electrical components. A metallic face sheet is secured onto at least one outer face, adding structural rigidity to the multilayer printed wiring board. A metallic face sheet can have apertures positioned to allow access to connection areas. RF components can be carried by a face sheet and operatively connected to connection areas. Antenna elements can be positioned on the same or an opposing face sheet and operatively connected to RF components to form a phased array printed wiring board (PWB) panel.

  • Patent number: 7495177
    Abstract: A printed wiring board manufacturing process comprises forming a conductive metal layer on at least one surface of an insulating film with a sputtered metal layer in between, selectively etching the conductive metal layer and the sputtered metal layer to produce a wiring pattern, treating the laminated film with a first treatment liquid capable of dissolving nickel of the sputtered metal layer, and treating with a second treatment liquid capable of dissolving chrome of the sputtered metal layer and also capable of eliminating the sputtered metal layer in the insulating film to remove a superficial surface of the insulating film exposed from the wiring pattern together with the residual sputtered metals in the superficial surface. A printed wiring board comprises an insulating film and a wiring pattern, wherein the insulating film in an area exposed from the wiring pattern has a thickness smaller by 1 to 100 nm than that of an area under the wiring pattern.

  • Patent number: 7470864
    Abstract: A multi-conducting through hole structure is provided. The multi-conducting through hole structure has a substrate, at least two signal lines and at least a reference line. The substrate has a through hole passing therethrough. The signal lines are disposed on a portion of an inner surface of the through hole and extended through the through hole. The reference line is disposed on a portion of the inner surface of the through hole and extended through the through hole, wherein the reference line is disposed between the lines for signal. Because the signal lines are separated by the reference line, the electromagnetic coupling generated by signals can be reduced to lower the cross-talk interference between signals passing through the through hole, so as to promote the signal-transmission quality.

  • Patent number: 7465882
    Abstract: Signal line conductors passing through vertical vias in an insulative substrate for supporting and interconnecting integrated circuit chips are provided with shielding conductors in adjacent vias that link respective power and ground planes. The shielding conductors' presence in positions around a signal via is made possible through the employment of power plane and ground plane conductive grids that are laid out in rhomboid patterns. The power plane and ground plane grids possess a left-right mirror relation to one another and are displaced to place the rhomboid's corners to avoid overlapping any of the grid lines.

  • Patent number: 7455533
    Abstract: An insulating resin layer 50 is formed on a surface of a conductor portion 2 by performing a plating pretreatment to the conductor portion 2 that has been formed on a surface of a wiring board substrate 1, and forming numerous dendrites 3 on the surface of the conductor portion 2 using an electroplating or chemical plating method. The insulating resin layer 50 is then formed by stacking an insulating resin plate 50 that has a semi-cured adhesive layer 40 formed thereon in advance on the conductor portion 2 and the dendrites 3, and then applying pressure and raising temperature for laminate bonding.

  • Patent number: 7450396
    Abstract: According to embodiments, small holes or openings may be cut on or through the ground plane(s) adjacent to a selected trace line, so that C and L will be changed accordingly. Then phase velocity will also be changed. As a result, the flying time from one location or point to a different location or point of the transmission line will also be changed. This concept applies to a single trace. Similarly, this concept may be applied to one trace of a differential pair of traces (e.g., so that the two parts of the differential signal transmitted at one point in time at a location on the pair arrive at the same time at another location of the pair).

  • Patent number: 7450394
    Abstract: A printer circuit board for mounting electrical components such as LEDs has outward edge protrusion on which an electrically conductive material is deposited such that the board itself can be used to make electrical contact in a pre-existing, commercially available fitting, such as a screw-in or base fitting designed to receive incandescent light bulbs. For a screw-in fitting the board can optionally be made slightly wider than the inner diameter of the fitting but be provided with at least one axially extending slit; the board is then compressed slightly but biased outward to provide better electrical contact when inserted into fitting.
