| 20120025859 | COMBINED PROBE HEAD FOR A VERTICAL PROBE CARD AND METHOD FOR ASSEMBLING AND ALIGNING THE COMBINED PROBE HEAD THEREOF - A combined probe head being disposed in a space transformer of a vertical probe card is provided, in which the combined probe head is used for differentiating or segmenting a layout area of the probes in the vertical probe card. The combined probe head may include a locating plate and sub-probe heads. The locating plate may include fixed portions. Each sub-probe head may include corresponding sub-dies and probes inserted between the sub-dies, and each sub-probe head is assembled and fixed in the corresponding fixed portion. Therefore, the layout area of the probes in the vertical probe card can be respectively differentiated or segmented from the sub-probe heads in order to avoid mutual interference under repair process. In addition, a related method for assembling and aligning the above mentioned combined probe head is provided. | 02-02-2012 |

| 20110221462 | PROBE CARD HAVING CONFIGURABLE STRUCTURE FOR EXCHANGING OR SWAPPING ELECTRONIC COMPONENTS FOR IMPEDANCE MATCHING AND IMPEDANCE MATCHING METHOD THEREFORE - A probe card having a configurable structure for exchanging/swapping electronic components for impedance matching and an impedance method therefore are provided. In the probe card, an applied force is exerted on the electronic component so as to make the electronic component electrically connected with at least one conductive contact pad of a supporting unit. The supporting unit is a circuit board or a space transformer. In order to facilitate the exchange or swap of the electronic component, the applied force can be removed. The probe card includes a pressing plate which can be moved between a pressing position and a non-pressing position. The pressing plate has a pressing surface which is contacted with the top end of the electronic component while the pressing plate is in the pressing position. Therefore, the applied force can be generated or removed by changing the positioning of the pressing plate. | 09-15-2011 |

| 20090007421 | METHOD FOR MANUFACTURING FLEXIBLE PRINTED CIRCUIT BOARDS - An exemplary method for manufacturing flexible printed circuit board is provided. A metal foil is supplied from a first feeding roller. The metal foil has a first surface and a second surface on two opposite sides of the metal foil. A first coverlay having a number of first openings defined therein is supplied from a second feeding roller and laminated on the first surface of the metal foil. Electrical traces are formed with the metal foil. A second coverlay having a number of second openings defined therein is supplied from a third feeding roller and laminated on the second surface of the metal foil. Each of the second openings registers with the respective first opening so that the electrical traces are exposed from the corresponding first and second openings. The method can improve quality and efficiency of manufacturing flexible printed circuit boards in a hollowed out form. | 01-08-2009 |

| 20100117462 | Damper Power-Generating System - A damper power-generating system includes a damper, a driving apparatus, and a generator. The driving apparatus simply consumes energy to do work for generation of electric power. That is, the work is done by utilizing the displacement due to the strong up-and-down vibration within a damper, wherein the displacement due to the up-and-down vibration drives a set of gear racks, which, in turns, drives gears having a one-way driving apparatus, so that rotation can be achieved in one direction, and, further, buffering springs and accelerative gears are used, so that speedy and uniform rotation can be achieved. | 05-13-2010 |
