  • Patent number: 11217955
    Abstract: A method for manufacturing an electrical connector is provided. A metal plate is provided, and defines multiple terminals. Each terminal has a base portion and an elastic arm connected to the base portion. A portion of a lower surface of the base portion defines a conducting area. The base portion is cut on the metal plate, thereby forming a cutting slot on the metal plate located at a side edge of the base portion. An insulating body is formed on the metal plate by injection molding, such that the insulating body fills the cutting slot. The insulating body covers only the base portion and not the conducting area and the elastic arm, thereby forming a through hole on the insulating body to expose the elastic arm. Then, the elastic arm is cut on the metal plate, thereby forming a through slot on the metal plate surrounding the elastic arm.

    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.

  • Patent number: 7772047
    Abstract: A semiconductor device having a redistribution layer, and methods of forming same, are disclosed. After fabrication of semiconductor die on a wafer, a tape assembly is applied onto a surface of the wafer, in contact with the surfaces of each semiconductor die on the wafer. The tape assembly includes a backgrind tape as a base layer, and a film assembly adhered to the backgrind tape. The film assembly in turn includes an adhesive film on which is deposited a thin layer of conductive material. The redistribution layer pattern is traced into the tape assembly, using for example a laser. Thereafter, the unheated portions of the tape assembly may be removed, leaving the heated redistribution layer pattern on each semiconductor die.

  • Patent number: 7748116
    Abstract: A method of creating an electrical contact involves locating a barrier material at a location for an electrical connection, providing an electrically conductive bonding metal on the barrier material, the electrically conductive bonding metal having a diffusive mobile component, the volume of barrier material and volume of diffusive mobile component being selected such that the barrier material volume is at least 20% of the volume of the combination of the barrier material volume and diffusive mobile component volume. An electrical connection has an electrically conductive bonding metal between two contacts, a barrier material to at least one side of the electrically conductive bonding metal, and an alloy, located at an interface between the barrier material and the electrically conductive bonding metal. The alloy includes at least some of the barrier material, at least some of the bonding metal, and a mobile material.

  • Patent number: 7716810
    Abstract: A method of manufacturing a commutator main body which has a cylindrical insulating body, and a plurality of segments arranged in an outer circumference of the insulating body. A short-circuit member is arranged in an end in an axial direction of the insulating body. The short-circuit member has a plurality of first short-circuit pieces and a plurality of second short-circuit pieces. A tabular insulating portion covers first coupling portions of the first short-circuit pieces, and second coupling portions of the second short-circuit pieces. The insulating portion has a restriction recess, and the end in the axial direction has a restriction projection. The restriction projection is engaged with the restriction recess, whereby the movement of the short-circuit member in the circumferential direction with respect to the commutator main body is restricted. Accordingly, the assembly of the short-circuit member in the commutator main body is facilitated.

  • Patent number: 7504925
    Abstract: An electric device generates a predetermined amount of heat in the event of a malfunction. The electric device is protected from overheating in that it is arranged, with a fuse in a circuit, such that the fuse and the electric device are thermally coupled to one another, so that the generation of the amount of heat by the electric device causes a fusible material in the fuse to melt. In this manner, the current terminal path of the electric device is interrupted.

  • Patent number: 7486480
    Abstract: Embodiments of the invention relate to making reconnection when a soldered connection fails in a head/slider used in a magnetic disk drive. In one embodiment, a solder mass deposited on a slider pad of a head/slider is separated from a lead pad and a solder ball connection is yet to be made between the slider pad and the lead pad. A shaping tip is heated to a temperature near a melting point of a solder. The shaping tip is moved in parallel with a surface of the slider pad toward the side of the lead pad to soften the solder mass. The solder mass is thereafter irradiated with a laser beam so as to form a solder fillet, thereby making a soldered connection between the lead pad and the slider pad.

  • Patent number: 7240429
    Abstract: A conductor pattern is formed on a resin film which is made of a thermoplastic resin. Each single-sided conductor pattern film has via-holes filled with an electrically conductive paste. A printed conductor pattern and a printed resistor are formed on a ceramic substrate. The single-sided conductor pattern films are laminated on the ceramic substrate. Then, the multilayered assembly is heated and pressed from both sides thereof to obtain a printed circuit board. During the heat and press treatment, respective single-sided conductor pattern films and the ceramic substrate bond together while the interlayer connection is obtained between the conductor patterns as well as between the conductor pattern and the printed conductor pattern.
