20090163069 | Burn-in socket with plated contacts - A burn-in socket for receiving an IC package comprises a socket body, a plurality of contacts mounted in the socket body and an actuator movably mounted upon the socket body. Each contact in the socket body includes a pair of clipping arms with tip portions at free ends thereof respectively. Solder balls attached to the bottom of the IC package are respectively clipped between the pair of the tip portions and thus the IC package should be brought into electrical contact with the contacts of the burn-in socket. The tip portion is plated with a Pd—Co layer for reducing the attachment of the Sn and preventing the impedance of the contacts to increase. Meanwhile, the IC package can be sucked up successfully without absorption from the contacts of the burn-in socket. | 06-25-2009 |

The contacts each comprise a base portion and a pair of arms received in the pin holes of the sliding plate. The actuator includes a frame and a number of actuating portion for driving the sliding plate to move in a transversal direction. The sliding plate includes a number of projections adjacent to contacts. Each projection and the pair of arms of an adjacent contact together define a receiving space and located at three sides of the receiving space, respectively. | 02-04-2010 |
20100055936 | ELECTRICAL CONNECTOR FOR TEST SOCKET - An electrical connector ( | 03-04-2010 |
20100062623 | IC SOCKET WITH FLOATABLE PRESSING DEVICE FOR RECEIVING TESTING IC PACKAGES OF DIFFERENT SIZES - An IC socket comprises an insulative housing adapted to accommodate an IC package and a pressing device pivotably attached to the insulative housing. The insulative housing defines some first pivoting holes at two opposite ends thereof and some second pivoting holes distant with the first pivoting holes. A pair of first shafts are assembled in the first pivoting hole of the insulative housing to pivotally latch the pressing device on the insulative housing and are movable in a vertical direction, so that the pressing device is floatable and can engage with different packages of different thickness. Two second shafts are assembled in the second pivoting holes. The IC socket further includes a plurality of spring members linking the first shafts and the second shafts to make the pressing device downwardly in a vertical direction. | 03-11-2010 |
20100120270 | TEST SOCKET ASSEMBLY HAVING STACKED INSULATIVE BOARDS - A socket assembly, for electrically connecting IC package and a printed circuit board, has a base with a cavity, a module received in the cavity of the base, a plurality of helical contacts received in the module and a cover mounted on the base. The module has a positioning board, a retaining board and a plurality of stacked insulative boards disposed between the positioning board and the retaining board. Each insulative board defines a plurality of through holes, which cooperatively define a plurality of separate helical channels to receive the contacts. | 05-13-2010 |
20100216328 | BURN-IN TEST SOCKET HAVING SPRING-BIASED LATCHES FACILITATING ELECTRICAL INTERCONNECTION BETWEEN CHIPS AND SOCKET WHEN ACTUATED - An electrical connector includes an insulative housing ( | 08-26-2010 |
20100221929 | BURN-IN SOCKET WITH SLIDING MEMBER MOVABLE IN DUAL DIRECTIONS - A burn-in socket comprises a base, a plurality of terminals received in the base, a lid mounted upon the base, and a sliding member mounted on the base. The terminal has a movable arm and a static arm, the lid has a number of actuating portions downwardly extending from the bottom thereof to drive the sliding member. The actuating portion of the lid drives the sliding member to move in both a longitudinal direction and a transverse direction, so that the movable arm moves not only in the longitudinal direction but also in the transverse direction to avoid interference with a static arm of an adjacent terminal. | 09-02-2010 |
20100311264 | BURN-IN SOCKET - A burn-in socket includes a base, a sliding plate mounted to the base, a number of contacts, and an actuator mounted on the base. The contact each has a base portion secured to the base and a pair of arms extending through the pin holes of the sliding plate. The actuator includes a frame and a number of actuating portion extending downwardly from the frame for driving the sliding plate to slide on the base in a first direction. The actuator includes a number of pushing portions contacting with the sliding plate and driving the sliding plate to move in a second direction opposite to said first direction. | 12-09-2010 |
