  • Patent number: 9615458
    Abstract: For producing a three-dimensional circuit component, an electronic component is mounted on a synthetic resin block. A plurality of electrically-conductive patterns used to establish an electrical connection to the electronic component are formed on the block along a three-dimensional shape of the block. An end of each electrically-conductive patterns is provided with a solder-disposed section. A solder is provided between the solder-disposed section and an opposed surface of the electronic component. The section of each electrically-conductive patterns other than the solder-disposed section and a section on which the electronic component is mounted is internally formed in the block. Since the section of each electrically-conductive patterns other than the section on which the electronic component is mounted is internally formed in the block, the electrically-conductive patterns are not unnecessarily exposed.

  • Publication number: 20170089784
    Abstract: A pressure sensor includes a pressure sensor element, a joint provided to a target member, and an attachment member that is fitted into the joint through the connection section and connected to the target member. Each of the pressure sensor element and the joint is formed of a material that is not embrittled upon being in contact with a fluid to be measured that embrittles a material, and more rigid than the attachment member. The connection section is subjected to a plastic deformation connection (metal flow). An expensive hydrogen embrittlement resistant material is used for the pressure sensor element and the joint that are brought into contact with the fluid to be measured, and an inexpensive material is used for the attachment member that is not brought into contact with the fluid to be measured, thereby reducing the production cost of the pressure sensor.
