  • Publication number: 20150334259
    Abstract: A circuit board includes: a printed board including SWB pads for wire bonding and lands; image sensor ICs mounted on the printed board by a thermosetting adhesive and including FWB pads for wire bonding to be electrically connected to the SWB pads by wire bonding; and surface-mount elements mounted on the lands by soldering, wherein the surface-mount elements and the lands are connected by solders including bromine-containing flux, and coating films are formed on surfaces of the solders to prevent attachment of bromine to the SWB pads and the FWB pads.

  • Patent number: 5912504
    Abstract: A semiconductor optical device is provided with a photo-electric conversion unit having plural photo-electric conversion elements and is entirely sealed by a sealing member. The photo-electric conversion elements are connected to external leads with electrical connectors. The distance D between a planar outer surface and a photoelectric conversion area satisfies the equation, D.gtoreq./2.multidot.l/tan .theta., where .theta. is a critical angle of total reflection of the sealing member with respect to air and l is the maximum length of said photoelectric conversion area.

  • Patent number: 5587814
    Abstract: In a color photoelectric conversion apparatus in which a plurality of semiconductor image sensors each having a plurality of light-receiving windows are arrayed, and a plurality of light-receiving windows in a main scanning direction constitute one color light-receiving element, the last light-receiving window or at least two light-receiving windows including the last light-receiving window of a first semiconductor image sensor of adjacent semiconductor image sensors, and the first light-receiving window or at least two light-receiving windows including the first light-receiving window of the next semiconductor image sensor constitute one color light-receiving element.

  • Patent number: 5583076
    Abstract: In a method for manufacturing a semiconductor photo-sensor, an assembly including a photoelectric conversion element having a photoreceiving section, and a lead terminal having an inner lead connected to the photoelectric conversion element by a bonding wire is provided. A light transmitting member is also provided within the cavity spaced apart from the photoelectric conversion element and at a light-incident side of the photoelectric conversion element, the light transmitting member having an inner surface facing an upper surface of the photoelectric conversion element and an outer surface opposite the inner surface. The photoelectric conversion element, the inner lead and the bonding wire are sealed by introducing a light transmitting resin into the cavity so as to provide a relation l<2.multidot.(d.sub.1 +d.sub.2).multidot.tan.theta..sub.1, wherein l is a length of the photoreceiving section of the photoelectric conversion element, d.sub.

  • Patent number: 5079190
    Abstract: A method for producing a resin-sealed photoelectric converting device which eliminates the problem of uneven resin refractive index produced when the resin is injected past the lead wires and over the light receiving elements. The photoelectric converting device has a photoelectric converting element, and wires for electrically connecting electrodes of the photoelectric converting element with lead electrodes. A transparent portion is present on the light receiving portion of the photoelectric converting element. The method includes the steps of placing the photoelectric converting element and the lead electrodes in a mold cavity having a resin-injecting gate; and injecting resin from the gate and guiding the injected resin which bypasses said wires to an area away from the photoelectric converting portion, and sealing the entire photoelectric converting element with the injected resin.
