Abstract: An IC package mounting device that includes a plurality of independently operative sliding latches or clips to secure the IC package to the device. The sliding latches are housed in guide slots that prevent the latches from becoming disengaged from the carrier assembly, with the guide slots being oriented at an angle relative to the lateral peripheral dimensions of the IC package.

Abstract: A socket for carrying an integrated circuit (IC) package. The socket, which is particularly useful for burn-in testing, includes a base 18 which houses a plurality of conductive contacts 46 and a movable top 108 which is shiftably connected to the base. A table 32 is connected to the base 18 and supports the IC package after insertion. The socket also includes a contact actuation plate 72 which is operably connected to the movable top 108 and is shiftable with the top. Latches 96 are shiftably connected to the base 18 and shift with the top 108 between latched and unlatched positions to secure the IC atop the table during testing. The actuator plate 72 may also include retractable location pins 82 to insure proper IC alignment in the socket.

Abstract: A connector for an integrated circuit (IC) chip to secure the IC chip during testing. The connector includes a unique latching system with a pivotal contact pad carried beneath a latch plate for self-adjusting alignment prior to engaging the leads of the IC chip. The latching system also includes an actuator and hook member pivotally connected to the latch plate in an over center movement fashion to increase the clamping force uniformly across IC leads.

Abstract: A socket for securing an integrated circuit (IC) during burn-in or test procedures. The socket includes a base which carries a plurality of electrically conductive contacts. Opposed hold down rollers are shiftably journaled in the base. The socket also includes a movable top connected to the base and a contact with the rollers. Movement of the top shifts the rollers between secured and open positions. A rotatable lever housed in the base is connected to an actuating arm which is also shiftable by movement of the top. The lever is operably associated with the contacts and shifts the contacts between an operative position in contact with the IC chip leads and a standby position spaced from the IC chip leads.

Abstract: A socket for carrying an integrated circuit (IC) chip. The socket includes a plurality of opposed contacts which have upper and lower integral beams. The socket also includes a spring-biased movable top with inclined inner side walls to urge the contacts into a latched position with the upper beam contacting a lead or a pod on the IC to establish electrical contact. As the top is pushed down, the resilient nature of the contacts allows the lower beam to ride up the inclined side wall into an unlatched position wherein the IC may be removed from the socket.

Abstract: A socket for securing an integrated circuit (IC) during burn-in or test procedures. The socket includes a base which carries a plurality of electrically conductive contacts. Opposed hold down latches are shiftably connected to the base and include outer cams. The socket also includes a movable top which has an integral nib for contacting the latch cams to effect shifting of the latches. A rotatable lever housed in the base is connected to an actuating arm which is shiftable by movement of the top. The lever is operably associated with the contacts and shifts the contacts between an operative position in contact with the IC leads and a standby position spaced from the leads.

Abstract: An IC carrier socket having a top with integrally molded guide pins for initially engaging and maintaining an IC carrier in the proper orientation and position during seating the carrier within the socket.

Abstract: A connector for an integrated circuit (IC) to secure the IC during testing. The connector includes a unique latching system which includes an actuator and a hook which are pivotally connected in an over-center movement fashion to significantly increase the clamping force from the force applied to latch the actuator or a connected latch plate.

Abstract: A chip carrier socket which includes conductive contacts each having an outwardly extending upwardly directed cantilevered projection which engages a moveable top forming a part of the socket. The top, when moved downwardly, relative to the base of the socket which carries the contacts forces the contacts outwardly to allow the insertion or removal of the chip carrier. The top includes a multiple-angled camming surface which engages the upwardly extending cantilevered projection of each contact to apply a more generally even force against the contact during depression or downward movement of the top.

Abstract: A modular socket for an integrated circuit package, wherein a single base is adapted to receive a plurality of replaceable contact modules having a variety of conductive lead counts. The modularity permits tooling of a single base to accommodate a variety of integrated circuit packages.The socket includes a lid pivotally connected to the base by a hinge and hinge pin. The hinge pin defines a pivot axis which is in a plane with the bottom surface of the lid to limit lateral movement on the contacts carried by the module.

Abstract: A zero insertion force socket using normally closed contacts and three adjacently overlying plates. Upon lifting the activating arm, a cammed cylinder is rotated which pushes the middle plate and pulls the top plate to thereby open the prongs of the contact for component lead insertion therebetween. Upon the activating arm being moved back into its original position the cammed cylinder rotates and the middle plate shifts back to its original position under the influence of a contact prong closing about the component lead as the top plate shifts back to its original position under the influence of the cammed cylinder.

Abstract: A socket device for an integrated circuit package having fine pitch or closely spaced leads or contact pads. The socket device includes a base having a platform for supporting the IC package. Opposed actuating latches are pivotally carried upon the base at opposite sides of the platform to accommodate receipt and retention of the integrated package. The socket device includes a plurality staggered contacts in multiple ranks at opposite sides of the platform adjacent the actuator latches. The contacts engage the actuator latches so as to be moved between open and closed positions upon pivotal movement of the latches.

Abstract: A chip connector which includes conductive contacts which electrically contact the carrier. The contacts include an outwardly extending cantilevered projection to allow the contacts to be shifted outwardly on downward engaging movement of the connector top to allow insertion or removal of the chip. The connector base includes a wall positioning part which biases the contacts into a preloaded or clamped position.
