  • Patent number: 10162016
    Abstract: A microelectronic device, possibly a packaged microelectronic device, contains a magnetic sensor component and magnetizable structural features. Magnetic moments of the magnetizable structural features are aligned parallel to each other. The microelectronic device is formed by applying a magnetic field so as to align magnetic moments of the magnetizable structural features with the applied magnetic field. Application of the magnetic field is subsequently discontinued. The magnetic moments of the magnetizable structural features remain aligned parallel to each other after the applied magnetic field is discontinued.

  • Patent number: 10126127
    Abstract: Printed circuit boards (PCBs) are configured with an athermalized mounting suitable for securing and positioning and the PCBs within an inertial measurement unit (IMU). The PCBs include integrated circuit (IC) components, such as accelerometers and/or gyroscopes, which require relative positional stability within the IMU environment in order to provide accurate results. The athermalized mounting configuration of the PCB enables the PCBs to experience thermal expansion within the IMU without causing significant displacement of the IC relative to the IMU environment.
