Abstract:
A layer of electrically insulating material is applied to a substrate and a component located thereon, in such a way that said layer follows the surface contours.
Abstract:
A film, based on polyimide or epoxy, is laminated onto a surface of a substrate under a vacuum, so that the film closely covers the surface and adheres thereto. Contact surfaces to be formed on the surface are uncovered by opening windows in the film. A contact is established in a plane manner between each uncovered contact surface and a layer of metal. This establishes a large-surface contact providing high current density for power semiconductor chips.
Abstract:
A switching device for switching a high operating voltage is described. The switching device-includes a first switching arrangement with a first self-conducting switching element), which has a control connector and a first and second main connector for forming a switching section. The switching device may include a second switching arrangement having a first and a second connector for forming a switching section, which is wired serially in respect to the switching section of the first switching arrangement. The second switching arrangement includes an optically triggerable switching element for switching the switching section of the second switching arrangement so it becomes conductive. The second connector of the second switching arrangement is connected with the control connector of the first self-conducting switching element.

Abstract:
An arrangement in which a first contact surface (2) for bonding one end (51) of the bonding wire (5) and a piezoelectric actuator (3) are fixed on a support body (1) and a second contact surface (4) for bonding another end (52) of the bonding wire (5) is fixed to the actuator by an unsupported support body (34). The second contact surface moves back and forth in relation to the support body by means of an actuator, at a frequency of between 0.1 Hz and a few KHz and in one or more directions (31, 31′, 31″). The arrangement is suitable for use in testing the endurance of bonding wire connections.
Abstract:
A circuit design includes an electrical circuit, which has at least one electronic component attached to a substrate and a flat conductor track electrically contacting the component. An elastic element is provided on the electrical circuit and a device applies a force to the elastic element so that the elastic element is pressed onto the electrical circuit. Thus, crack formation in a solder under the component is prevented.
