  • Apparatus related to an inductive switching test
    Patent number: 9097759
    Abstract: In one general aspect, an apparatus can include an energy storage device configured to store energy during an unclamped inductive switching test of a target device, and a switch device configured to shunt at least a portion of energy away from the target device in response to the target device changing from a breakdown state to a failure state.
    Type: Grant

    Assignee: Fairchild Semiconductor Corporation
    Inventors: Daren W. Keller, John T. Andrews
  • INTEGRATED WIRE BONDER AND 3D MEASUREMENT SYSTEM WITH DEFECT REJECTION
    Publication number: 20150162299
    Abstract: An apparatus comprises a wire bonder system including a wire bonding device, a measuring device and a rejection device. The wire bonding device is configured to attach wire bond type electrical interconnect to an electronic assembly. A wire bond is formed between a first semiconductor device and a second electronic device to form at least a portion of the electronic assembly. The measuring device is configured to perform a three dimensional measurement associated with a wire bond, and the rejection device is configured to identify an electronic assembly for rejection according to the three dimensional wire bond measurement.
