  • Publication number: 20240120317
    Abstract: A fan-out semiconductor device includes stacked semiconductor dies having die bond pads arranged in columns exposed at a sidewall of the stacked semiconductor dies. The stacked dies are encapsulated in a photo imageable dielectric (PID) material, which is developed to form through-hole cavities that expose the columns of bond pads of each die at the sidewall. The through-hole cavities are plated or filled with an electrical conductor to form conductive through-holes coupling die bond pads within the columns to each other.

  • Patent number: 11924964
    Abstract: Devices and methods are described for reducing etching due to Galvanic Effect within a printed circuit board (PCB) that may be used in an electronic device. Specifically, a contact trace is coupled to a contact finger that has a substantially larger surface area than the contact trace. The contact finger is configured to couple the electronic device to a host device. The contact trace is electrically isolated from the rest of the PCB circuitry during a fabrication process by a separation distance between an exposed portion of the contact trace and an impedance trace. The contact finger and the exposed portion of the contact trace are plated with a common material to reduce galvanic etching of the contact trace during fabrication. The contact trace is then connected to the impedance trace using a solder joint.

  • Patent number: 10675797
    Abstract: A stainless steel and synthetic resin composite molded body and preparation method thereof. After the surface of the flat and even stainless steel had anchor effect, it was connected with various synthetic resin pieces by means of insertion molding. Regardless of the material of the stainless steel piece, the indenting test proved that the strength, of over 15 N/mm2 after connection enabled stable tightness. With insertion molding of the stainless steel piece having anchor effect in the present invention, composite molded products comprising various resin parts can be produced if no displacement or height difference occurs.

  • Patent number: 7278155
    Abstract: The present invention discloses a single sign-on system for remotely operating an application program via a network. With the present invention, a user may operate a client computer, which connects and signs on to a single sign-on server to retrieve sign-on information. Then, the client computer connects and signs on to an application program server with the sign-on information, and updates the sign-on information saved in the single sign-on server by sending the sign-on information back to the single sign-on server.

  • Publication number: 20040078762
    Abstract: A distributed communications network apparatus and method employ a plurality of static information pages in a plurality of languages. The apparatus and method also employ a language selection utility for purposes of selecting a static page within the plurality of static pages, in accord with a language preference determined with respect to a requester. The requester may then be directed to the static page within the plurality of static pages, in accord with the language preference. By employing the plurality of static pages in conjunction with the language selection utility, the apparatus and method are provided with enhanced efficiency.
