  • Patent number: 11830611
    Abstract: According to one embodiment, a device management apparatus includes processing circuitry. The processing circuitry acquires information indicating occurrence of a first failure prediction of a first device. The processing circuitry adjusts detection sensitivity of a second failure prediction of a second device relating to the information based on relevance between the first device and the second device. The second device is different from the first device.

  • Publication number: 20230298990
    Abstract: A semiconductor device includes a lead, a semiconductor element, and a sealing resin. The lead includes an island portion having an obverse surface and a reverse surface facing opposite sides in a thickness direction. The semiconductor element is mounted on the obverse surface of the island portion. The sealing resin covers the semiconductor element and the island portion. The sealing resin has a first portion and a second portion that overlaps with the island portion as viewed in the thickness direction. The sealing resin is configured such that the infrared transmittance of the second portion is higher than that of the first portion.
