    Abstract: A monolithic, multi-layer heating element forms the high temperature tip of a glow plug assembly. The heating element includes a conductive core which is surrounded by an insulator layer, which in turn supports a resistive layer. An optional conductive jacket can surround the resistive layer. These layered components are pre-formed in prior operations and then assembled one into the other to form a precursor structure. The precursor structure is transferred to a die, where it is compressed to form a so-called green part having dimensional attributes proportional to the finished heating element. The individual layers remain substantially intact, with some boundary layer mixing possible to enhance material-to-material bonding. The green part is sintered to bond to various materials together into an essentially solid mass. Various finishing operations may be required, following which the heating element is assembled to form a glow plug.

    Abstract: In order to make it possible to produce a secure and permanent contact connection between an electrical conductor made from a soft material, in particular an aluminum conductor, and a contact element made from a harder material, the conductor is encapsulated at least partially in a contact region by an electrically conductive material. The electrically conductive material is harder than the soft material of the conductor. The electrically conductive material is applied with the aid of a thermal spraying process, with the result that there is a pressure-free electrical connection between the soft material and the sprayed-on material. Electrical contact is made with the contact element indirectly via the sprayed-on material. The thermal encapsulation by the spraying in the contact region makes it possible for a reliable electrical contact to be made even in the case of soft materials having a tendency towards cold flow.

  • Patent number: 7168154
    Abstract: An integrated lead suspension includes a solder ball that is placed between a lead wiring pad provided on a flexure of the suspension, and a bonding pad provided on a slider of a head gimbal section. The lead wiring pad and bonding pad are soldered by melting the solder ball. As a result, there is provided a recessed section into which a solder ball is placed by way of surface raised sections, using gravitational force, in the vicinity of the center line of the surface of the lead wiring pad. In this way the position of the solder ball is not displaced from the center line when a bonding pad and lead wiring pad are connected by means of a solder ball.

  • Patent number: 7168165
    Abstract: During fabrication of an electrical medical lead, a cut end of a stranded wire conductor is subjected to electrical current sufficient to heat and weld the strands together upon discharge of a high voltage between the cut end and a ground metal plate formed of a material of the stranded wire conductor. The discharge of weld energy between the stranded wire cut end and the ground plate induces heat in the wire strands at the stranded wire cut end and the ground plate sufficient to transfer conductive material from the ground plate to fuse the wire strands together. The fusing inhibits unraveling of the wire strands at the fused cut end, whereby the insertion of the stranded wire cable through a lead body lumen and the connection of the fused stranded wire cut end to a further lead component, e.g., a proximal lead connector element or distal electrode, is facilitated.

  • Patent number: 7153764
    Abstract: A method of manufacturing a semiconductor device includes an improved bump forming process. The bump forming process includes a bump forming step for forming a bump on the pad by feeding a gold wire from a capillary while moving the capillary; a sliding step of slightly moving the capillary in an almost horizontal direction after the formation of the bump to reduce the strength of the base portion of the gold wire connected to the bump; and a wire cutting step of cutting the gold wire at the base portion after the sliding step. In the sliding step, a moving speed of the capillary is made smaller than that in the bump forming step.

  • Patent number: 7146722
    Abstract: A bond pad structure comprising two bond pads, methods of forming the bond pad structure, an integrated circuit die incorporating the bond pad structure, and methods of using the bond pad structure are provided. Each of the bond pads comprise stacked metal layers, at least one lower metal layer and an upper metal layer. When the two pads are connected by a conductive material, they function as a single pad. The lower metal layer of one of the bond pads forms an extension that extends beneath the upper metal layer of the other of the bond pad. The lower metal extension functions to block the etching of a dielectric layer that is put down over the upper metal layers and the underlying substrate, for example, during a passivation etch to form the bond pad opening, to protect the substrate from damage.

  • Patent number: 7146723
    Abstract: The mechanical connection of contacts through induction soldering is improved. To which end, a plastic dome is produced through preliminary encapsulation by injection molding of at least one contact and subsequent final encapsulation, where the two contact geometries to be joined can, for example, be premated. With an appropriate solder preform, the plug-in connection can be secured through induction soldering by enclosing this dome. The appropriate tool is then placed over the plastic dome, by which the heat generated melts the solder preform and securely joins the two contacts to one another.

  • Patent number: 7134190
    Abstract: The present invention is an automated wire harness machine (40) capable of manufacturing a wire harness (42) unique in-part due to the automation process. The novel wire harness is generally a plurality of bundled, preferably un-stripped, insulated wires (46). Each un-stripped end portion (180, 182) of each wire is preferably terminated to one of a series of electrical connectors (44) of the wire harness. Each connector has at least one wafer (52) which houses a plurality of terminals (54) preferably crimped and electrically terminated to the ends of the wires. The wire harness machine preferably utilizes a pallet (56) which holds all of the wafers of one wire harness. A conveyor (58) transports the pallet and wafers through a series of stations which perform automated manufacturing steps. The first station is a terminal inserter (64) which inserts and locks the terminals within pre-assigned cavities (114) of the wafers.
