  • Patent number: 7331723
    Abstract: Provided are an enhanced structure of a coplanar waveguide that is a kind of transmission line used for optical communication for radio frequency (RF), and an optical communication module employing the same. While having a basic structure including a conductive strip and ground strips at both sides of the conductive strip on a dielectric substrate, the coplanar waveguide has the structure in which metal patterns of a portion of the conductive strip located around points where an RF propagation direction is changed and of a portion of an inside ground strip are removed to make electrical lengths of an outside ground strip and the inside ground strip similar each other. Using the coplanar waveguide, it is possible to fabricate an optical module that has an optimized RF characteristic and also can freely change an RF propagation direction of several tens GHz, without an additional process.

  • Publication number: 20080029923
    Abstract: A method for manufacturing a tape wiring board in accordance with the present invention may employ an imprinting process in forming a wiring pattern thereby reducing the number of processes for manufacturing a tape wiring board and allowing the manufacturing process to proceed in a single production line. Therefore, the manufacturing time and cost may be reduced. A profile of the wiring pattern may be determined by the shape of an impression pattern of a mold. This may establish the top width of inner and outer leads and incorporate fine pad pitch. Although ILB and OLB process may use an NCP, connection reliability may be established due to the soft and elastic wiring pattern.
