Abstract:
A pedestal connector that incorporates one or more grouped element channel link transmission lines is seen to have a dielectric body and two opposing contact ends that are intended to contact opposing contacts or traces. The dielectric body has an S-shaped configuration such that the transmission lines supported thereon make at least one change in direction, thereby permitting the use of such connector to interconnect elements lying in two different planes. The transmission lines include slots that extend within the frame and which define opposing, conductive surfaces formed on the dielectric body which are separated by an intervening air gap.

A circuit board, for an electronic circuit having a passive circuit component, has a component region, a non-component region, and circuit wiring conductors on its surface. The component region includes a polymer composition comprising a mixture of polymer resin and filler material that, in combination with the circuit wiring conductors, forms the passive circuit component.

The present invention discloses a printed circuit board. The printed circuit board is made by the method of providing a substrate; forming a first circuit on the substrate; depositing a thin film on the substrate; building an electronic component on the substrate by the thin film and allowing the electronic component to electrically connect the first circuit; forming a blanket dielectric layer enclosing the electronic component; and removing the substrate.
Abstract:
A method is provided for the punching of a bridge break and thereafter sealing the bridge break during the injection molding process of the lead frame. The bridge breaking tool is placed over the bridge that is to be broken. The collar presses down on the circuit and the punch presses down on the bridge with enough force to form the bridge break. Once the bridge break is formed the punch is retracted from the cavity of the template and molten polymer is injected to flow around the ends of the bridge break. The bridge breaking tool's hold down collars and retracted punch form a molding area for molten polymer to flow over the bridge break and the exposed circuit area. The bridge breaking tool is retracted after the bridge break is encased in the cured molten polymer and the cured molten polymer forms a lead frame structure.
Abstract:
Methods of manufacturing optical transceiver modules using lead frame connectors that connect optical sub-assemblies to printed circuit boards. The lead frame connectors include a conductive lead structure that is encased in an insert injection molded plastic casing. The lead frame connector is aligned with the leads that protrude from the back end of the corresponding optical sub-assembly (OSA). The leads pass through corresponding holes in the lead frame connector and are soldered to the conductors of the lead frame assembly. Once the soldering has been performed, the combined OSA and lead frame connector becomes a surface mount device that can then be mounted to the PCB. Assembling an optical transceiver using the lead frame connectors is generally less expensive and more reliable compared to the use of conventional flexible printed circuit board connectors.
Abstract:
A casing (10) is formed by insert molding using an inner portion (30) holding busbars (20) as an insert. The inner portion 30 includes an interlocking portion (33) to be hooked in a mold for molding the casing (10), and is so positioned and supported in the mold by the presence of the interlocking portion (33) as to project from the inner wall surface of the mold. The interlocking portion (33) is formed to project toward the inside of the casing (10) from the inner surface of the casing (10). The casing (10) is formed by covering the inner portion (30) excluding the interlocking portion (33) by a resin portion (13).

A flexible circuit has a roll-molded thermoplastic resin base sheet with an integrally molded mounting structure located to receive a light emitting diode device in an illuminating position. The mounting structure is a pin receptacle constructed to receive a pin of the light emitting diode device. An electrically conductive portion is carried by the resin base and positioned for electric connection to conductors of the device. Another flexible circuit carries discrete integrated circuit chips and a field of fastener elements extending from a surface of a resin strip carrying conductive traces interconnecting the chips.
Abstract:
Exemplary embodiments of the present invention illustrate lead frame connectors for connecting optical sub-assemblies to printed circuit boards in optical transceiver modules. The lead frame connectors include a conductive lead structure that is encased in a plurality of polymer casings. The polymer casings provide electrical insulation for the conductors in the lead frame as well as mechanical support for the finished component. One or more passive components can mount to the conductors of the lead frame connector to aid with impedance matching between an optical sub-assembly, the lead frame connector, and the printed circuit board. The lead frame connectors connect to the leads associated with the optical sub-assemblies and are surface mounted onto the printed circuit board to establish connectivity between the optical sub-assembly and the printed circuit board.
