20150068796 | PRINTED CIRCUIT BOARD INCLUDING CONTACT PAD - Provided is a printed circuit board (PCB) used as a signal transmission line of a terminal, comprising a first ground layer elongating in one direction, a first dielectric layer deposited on a top of the first ground layer and elongating in the same direction as the first ground layer, a signal transmission line deposited on a top of the first dielectric layer and elongating in the same direction as the first dielectric layer, a ground pad elongating from one end of the first ground layer and in contact with an external ground, and a signal line pad extended from one end of the signal transmission line and in contact with an external signal line. | 03-12-2015 |
20140154906 | Connector for Preventing Unlocking - Disclosed is a connector for preventing unlocking which includes a signal pin transferring a signal; a body into which the signal pin is inserted and which is electrically isolated from the signal pin; a first housing having a hollow portion into which one end of the body is inserted, a thread groove and at least one protruding portion or a plurality of fixing grooves formed at an inner circumferential surface of the other end thereof; and a second housing having a hollow portion into which the other body end is inserted and through which the second housing is moved along an outer circumferential surface of the body in an axial direction. | 06-05-2014 |
20110121851 | PROBE CARD - A probe card of a semiconductor test apparatus having a plurality of space transformers supporting probe units of the probe card is provided. A probe card of the present invention includes a plurality of probe units, each comprising a guide member and at least one probe secured by the guide member and contacting a chip pad to be tested; a plurality of space transformers arranged below the respective probe units, each space transformer having wires electrically connected to lower terminals of the probes; a frame having a plurality of guide holes for fixedly positioning the respective probe units; an interposer array arranged below the space transformers for supporting the space transformers, interposer array comprising electrical connection means for supplying test signals to the wires of the space transformers; and a printed circuit board arranged below the interposer array for supporting the interposer array and electrically connected to the electrical connection means for supplying the test signals. In the probe card of the present invention, the probe units are independently supported by respective space transformers such that it is possible to reduce thermal distortion of the probe card and simplifying the manufacturing and repairing processes. | 05-26-2011 |
20110031991 | PROBE BLOCK - A probe block mounted on a probe card is provided for achieving fine pitch probes. A probe block for a probe card of a semiconductor test device according to the present invention includes a guide member and a probe. A guide member includes pairs of upper and lower holes and middle holes each interconnecting the upper and lower holes of each pair. A probe includes a first pin tip protruded through a corresponding upper hole for contacting a pad of a device to be tested and a second pin tip protruded through a corresponding lower hole for transferring an electrical signal to the device and a bridge part situated within the middle hole for interconnecting the first and second pin tips. The upper, lower, and middle holes allow the probe to elastically moves in vertical direction. The probe block of the present invention is advantageous in that the probes are supported by guide members so as not to be bent while maintaining a fine pitch. Also, the probe block of the present invention is advantageous in fabrication and repair since probes are elastically contacted rather than directly bonded to the circuit substrate of the probe card. | 02-10-2011 |
20100015849 | COAXIAL CONNECTING DEVICE - A coaxial connecting device is provided for making an electrical connection between a coaxial cable and a device under test. A coaxial connecting device electrically connects a coaxial cable to a signal pad and a ground pad. The coaxial contractor of the present invention includes a signal pin for electrically connecting a signal conductor of the coaxial cable to the signal pad; a ground connector for electrically connecting a ground conductor of the coaxial cable to the ground pad; a cylindrical guide tube surrounding the ground conductor for elastically contacting the ground connector while maintaining a predetermined distance with the signal pin; and a dielectric member surrounding a part of the signal pin for electrically isolating the cylindrical guide tube and the signal pin from each other and coaxially maintaining the guide tube and the signal pin. The coaxial connecting device of the present invention minimizes a contact path between the ground conductor of a coaxial cable and a ground pad and provides impedance matched coaxial signal transmission link, resulting in improvement of frequency characteristics. | 01-21-2010 |
