    Abstract: Aspects include a hybrid socket dynamic warp indicator for socket connector systems and methods of using the same to measure the warpage of a printed circuit board assembly. The method can include providing a printed circuit board having a plurality of pads and a socket. A warp indicator having a plurality of solder joint connections and a resistor array is electrically coupled to the printed circuit board to build a printed circuit board assembly. The printed circuit board assembly is subjected to a thermal event. A resistance across the resistor array is measured after the thermal event.

  • Patent number: 11867650
    Abstract: Optical component integrity monitoring circuitry monitors an optical component integrity sensing path in an optical component. If a rise in resistance of the sensing path is detected, the circuitry prevents the optical component from emitting light. The optical component may have a light-emitting device that emits light through an optical element. The sensing path may have a first path that is used to detect damage to the optical element and a second path that is coupled to a package covering the optical element and light-emitting device. The first path may have a segment formed from a metal trace on the optical element and a segment formed from a wire bond, providing mechanical compliance to tolerate strains expected in the use case. The second path ensures that the package is present to constrain movement of the optical element and its wires within a safe envelope defined by the package interior.

  • Patent number: 11846668
    Abstract: A method for assessing the state of damage of a semiconductor module that is subject to operational loading, in particular a semiconductor module of a drive system converter, that includes at least one semiconductor component arranged on or in a support structure. It is possible not only to estimate a spent service life for the entire semiconductor module, but also to detect unexpected or undesirable loading states and thus a premature reduction of the remaining service life of the semiconductor module. Continuous load assessments are thus possible already during the operation of the semiconductor module and allow interventions to be made in good time.
