The second resistor, formed on the outer layer, can have a smaller area than the first resistor. Accordingly, the usable area of the outer layer is increased to thereby reduce the size of the multilayer wiring board. | 01-20-2011 |
20120007781 | ANTENNA MODULE - There is provided an antenna module. The antenna module according to the present invention may include a patch antenna resonator formed on a surface of a dielectric substrate; and a surface wave-radiation resonator disposed to be separated from the patch antenna resonator, and formed to surround the patch antenna resonator so that signals from the patch antenna resonator are radiated. In this instance, the signals may flow on the surface of the dielectric substrate. | 01-12-2012 |
20120013360 | Method of repairing probe card and probe board using the same - There are provided a method of repairing a probe card and a repaired probe board. The method of repairing a probe card includes: in a board body composed of a sintered ceramic having first and second pillar surfaces disposed at a position opposed to each other, preparing the board body including a plurality of main channels for electrically connecting a first pad formed on the first pillar surface to a second pad formed on a second pillar surface and reserved channels disposed to be adjacent to the main channels to repair to damaged main channels; when the main channels are damaged; removing the first and second pads formed in the main channels and the reserved channels; forming cavities by partially removing the board between the damaged main channels and the reserved channels adjacent to the main channel; and forming repair connection parts in the cavities in order to electrically connect the damaged main channels to the reserved channels adjacent thereto. | 01-19-2012 |
