  • Patent number: 8923005
    Abstract: An electrical component and a method for the manufacture thereof, comprising a connection arrangement between an active surface of an electrical component and a carrier, wherein electrical connecting elements are disposed in a connection zone on the active surface and/or on the carrier, and at least one spacer element is provided, which is disposed on the active surface and/or on the carrier. The at least one spacer element has a smaller height than the connecting elements before the connecting elements are reflowed to produce the electrically conductive connection, and is preferably disposed in an edge region of the connection zone.
    Type: Grant
    Filed: February 20, 2012
    Date of Patent: December 30, 2014
    Assignee: Micro Systems Engineering GmbH
    Inventors: Rainer Dohle, Florian Schuessler, Rolf Diehm, Oliver Kessling, Thomas Oppert
  • Patent number: 8450611
    Abstract: A connecting wire having an electrically conductive core, preferably provided by a wire or ribbon, with a coating provided on the surface of the core. The coating is composed of a nitrogen-containing tantalum alloy or tungsten alloy, and also optionally contains silicon as an additional alloy component. A manufacturing method for producing such a connecting wire involves passing a wire or ribbon core past a coating source to apply the coating.

  • Publication number: 20040120371
    Abstract: An improved electrical contact structure can be manufactured by plating a component of a first material such as molybdenum with a second material such as copper or silver. The first and second materials are selected to provide a desired effective coefficient of thermal expansion (CTE) and electrical conductivity. The contact structure can be made very thin for implementations in which multiple lasers are to be stacked closely together. The manufacturing processing can be carried out very inexpensively by first etching the outline of multiple components in a sheet of the first material and then plating the etched sheet with the second material.

  • Patent number: 6424667
    Abstract: Laser modules that are operated intermittently are prone to stop operating after only a few thousand cycles or less. The laser modules sometimes experience a significant increase in operating temperature before they stop operating and, in some cases, manifest an opening of the electrical circuit that connects the laser diodes in the stack of laser subassemblies. In extreme cases, the laser module disintegrates into component subassemblies. These problems arise from structural failures in affixing agents like solder that are used to affix component parts to each other. The structural failures are caused by cyclical thermal expansion and contraction of component parts that exceed the elastic limit of the solder.

  • Patent number: 5920584
    Abstract: A high-power diode laser and a method for mounting same are described. Predetermined breaking locations in the laser bar are provided which, during cooling after the laser bar has been soldered to a heat sink having a smaller thermal expansion coefficient, lead to breakage at defined locations between the single laser diodes of the laser bar. As a result of the physical division of the laser bar, it is possible to use a solder which has low ductility (hard solder) at room temperature, since destruction of the single laser diodes of the laser bar as a result of mechanical stresses can be ruled out.
