  • Electronic component and method of production thereof
    Patent number: 6262513
    Abstract: An electronic device and a fabricating method for fabricating the electronic device, the electronic device comprising; a surface acoustic wave device 3 having a main surface thereon having a transducer portion 4 and wiring patterns 5 connected electrically to the transducer portion; a printed circuit board 1 having wiring patterns 2 formed at least on one main surface thereof; a plurality of conductive bumps 6 which connect electrically both of the mutually opposed wiring patterns and form a space portion 10 between the surface acoustic wave device 3 and a printed circuit board 1; and resin portion 11 which, by heating/melting and hardening, makes an intimate contact with other main surface of the device and coats the device 3 and seals the device 3 together with the printed circuit board 1, wherein, by employing a highly thixotropic and viscous thermo-setting resin compared with a conventional one, an electronic device having a simple structure can be provided and fabricating process for fabricating the elec
    Type: Grant

  • Image sensor with means to adjust capacitance of signal leads
    Patent number: 4679088
    Abstract: Image sensor wherein there are provided a charge storage type photoelectric conversion section and a drive circuit including an integrated circuit on a substrate, and with these being connected by conductive strips, characterized in that capacitance adjustment conductive strips extend from the drive circuit section, and are arranged so as to pass underneath or close to the photoelectric conversion section and reduce variations in stray capacitances in the conductive strips.
