  • Publication number: 20200412213
    Abstract: A method of manufacturing a core product includes injecting molten resin into a resin injection portion provided in a core body so as to extend in a longitudinal direction of the core body, and forming a core product by welding the core body. A buffer region is set between the resin injection portion and a periphery of the core body in a lateral direction of the core body. The core product is formed by welding the core body so that a weld bead formed on the core body is prohibited from reaching the buffer region, and so that the weld bead is spaced apart from the resin injection portion in the lateral direction of the core body.

  • Publication number: 20200294874
    Abstract: A case includes a terminal disposition portion which includes a disposition surface projecting from an inner wall surface toward an open area, exposes an exposure region on a front surface of an external connecting terminal, and embeds therein a rear surface of the external connecting terminal. In the case, at at least part of both sides along a pair of opposite sides of the exposure region, the disposition surface is located between the front surface and the rear surface to have a level difference to the front surface. In a semiconductor device with the above-described configuration, the case does not extend to the exposure region on the front surface of the external connecting terminal. Therefore, no encapsulation resin flows into an interfacial debonding gap between the external connecting terminal and the case, thus curbing further advance of the interfacial debonding.

  • Patent number: 10688779
    Abstract: A screen printing apparatus includes an inspection region setter and an operation stop controller. The inspection region setter sets an inspection region in an inspection plane that intersects with a moving path of a mask until the mask positioned at a printing-job performing position moves to a mask shelter position by the moving mechanism. In addition, the inspection region setter excludes a passing region of the mask from the inspection region while the mask to be positioned at the mask shelter position passes over the inspection plane from the printing-job performing position.

  • Patent number: 9397015
    Abstract: A semiconductor device has an insulating substrate, a semiconductor element which is mounted on the insulating substrate, a hollow casing which surrounds a peripheral edge of the insulating substrate to contain the semiconductor element therein, and a sealing material which is charged into the casing to seal the inside of the casing. The casing has protrusion portions each of which partially protrudes from an upper surface of the casing. Thus, it is possible to provide a semiconductor device in which poor external appearance or lowering of adhesion to a cover can be prevented even when a sealing material is injected up to the vicinity of an upper surface of a casing.
