Abstract:
Compact sub-assemblies of flexible circuits and drivers are provided. The sub-assemblies can occupy less space in an electronic device than conventional sub-assemblies. In one or more embodiments of the present invention, the flexible circuits can be attached to or wires can be disposed on portions of the substrate that previously were unoccupied in conventional sub-assemblies. In one or more embodiments, the sub-assemblies of the present invention also can have wires disposed underneath the driver or vary the width of the wires. In one or more embodiments, the sub-assemblies of the present invention also can have composite wires that occupy less space than wires of conventional sub-assemblies, while still maintaining similar energy flux.
Abstract:

Abstract:
A method of making a printed circuit board panel, a printed circuit board panel made according to the method, and a system incorporating a printed circuit board provided onto the panel. The printed circuit board panel has a panel top edge, a panel bottom edge parallel to the panel top edge, and two parallel panel side edges, and further includes a first set of fiber bundles extending at the predetermined angle with respect to the panel side edges, and a second set of fiber bundles extending at the predetermined angle with respect to the panel top edge.
Abstract:
An apparatus is disclosed. The apparatus comprises a device and a counter system coupled thereto. The counter system provides an indication of a number of times the device is inserted into a slot. Through the use of the device disclosed above, a history and a number of insertions of a particular device within a system can be known and therefore it can be determined if the integrity of the device is threatened.
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:
According to one embodiment, a component-embedded printed circuit board is provided with a built-in component mounted on a component mounting surface of a substrate and enclosed by an insulating layer, an interior pattern layer for heat radiation which is provided on the opposite side of the built-in component from the substrate and radiates heat generated from the built-in component, and an exterior pattern layer for heat radiation connected to the interior pattern layer for heat radiation.
Abstract:
A shielding case for accommodating a wiring board includes a board mounting member with a fitting member formed at an outer frame thereof so that the wiring board is fixed and held to the board mounting member through fitting of the fitting member into a through hole formed at the wiring board.
Abstract:
A filter includes a coil leading structure and at least one coil. The coil leading structure includes a board and at least one pin. The pin is disposed at a side of the board and formed integrally with the board as a monolithic piece. The core is disposed on the board and has at least one end to be coupled with the pin.
Abstract:
An alignment structure of individual printed circuit board and method thereof are disclosed. The alignment structure of individual printed circuit board includes a panel body and an assembling part. An aligned part having a geometric feature is disposed on an inner side of the panel body. The assembling part coupled with an individual printed circuit board is similar to the geometric feature of the aligned part so that the individual printed circuit board is combined with the panel body.
