  • Patent number: 4996476
    Abstract: A test clip is provided which has multiple contacts that can engage the leads of a surface mount integrated circuit device whose leads are very closely spaced, while being reliably held down to the circuit device during a test procedure. The test clip has a housing with a recess (72, FIG. 10) that very closely recieves the top of the body of the circuit device (12) to align the clip with the circuit device, the clip being devoid of engagement with the lower part of the device. Instead, the test clip relies solely on frictional engagement of its contacts (24) with the circuit device leads (64) to hold down the test clip. Each contact has a first part (80) that initially lies against a contact-locating outer surface (82) of the housing. Each contact also has a second part (84) that extends below the contact-locating outer surface and that is positioned to be outwardly deflected slightly as it wipes across a circuit device lead, as the test clip is moved directly downwardly against the circuit device.

  • Patent number: 4970460
    Abstract: A controlled impedance testsite for the testing of integrated circuits, including matched impedance cables. Decoupling capacitors are used in the matched impedance cables in test situations where high frequency decoupling is required. The testsite includes a socket style ejector and a spring return. The contacts are a flat wire style affixed to the flexible Kapton matched impedance cables. A contact board and BUS board are positioned for decoupling purposes at one end of each cable adjacent to the contact area of the testsite and the integrated circuit to be tested. A hard PWB with connection pins affixed is used as a termination contact point, and is positioned at the opposing end of each flexible cable.

  • Patent number: 4956604
    Abstract: A contactor assembly for testing electronic devices that are packaged with a dual-in-line pin array has an insulating base that mounts two rows of contacts, each adapted to flex into electrical connection with a pin of the device, and a pair of flexible ground planes each spaced closely from an associated one row of said contacts. A flexible, insulating spacer maintains the ground planes and their associated row of contacts with a substantially fixed spacing there between during the flexural movement of said contacts. In the preferred form, the upper edge of the ground planes adjacent the pins includes an arrangement for securing a chip electronic device, a capacitor or a resistor. The other end of the chip mounts a contact tip that makes electrical connection with an associated pin when the associated contact also connects with the pin. The signal path provided by the holder, chip and tip is extremely short, preferably less than 0.150 inch.

  • Patent number: 4797118
    Abstract: A test adapter is provided for connection to a SOIC (small outline integrated circuit) carrier which can be locked to the carrier during test, has a relatively low profile thereby increasing the adapter's stability, and is very simple in construction. The adapter includes a one piece integral frame having two slots in which a pair of contact housings are mounted. The sidewalls of the frame running along the slots are resilient so that they will deform when the contact housings are mounted into the slots. A cam device is mounted on the housings above the frame. When the cam device is actuated, it pivots the housings to bring the contacts thereon into firm engagement with the leads of the carrier.

  • Patent number: 4735580
    Abstract: A test adapter is provided for connection to a PLCC (Plastic Leaded Clip Carrier), hereinafter referred to as a carrier, which assures accurate alignment with the carrier, which can be locked to the carrier during a test, which has a width only slightly greater than that of the carrier to enable testing of closely mounted carriers, and which can be simply constructed. The adapter includes an inner housing that bears against the top of the carrier and four contact frames pivotally mounted on the housing and carrying contacts that engage leads of the carrier. Each contact frame has separators between the contacts, the separators passing between the leads of the carrier to directly engage the sides of the carrier housing. The lower surface portions of the separators are slightly angled from the vertical so when they press against angled surfaces on the carrier housing sides, the adapter is locked to the carrier.

  • Patent number: 4710134
    Abstract: Chip carrier connector comprises a housing having a base and walls extending normally therefrom. The housing is movable relative to terminals between a first position and a second position. When the housing is moved to the second position, the terminals are moved inwardly thereby pressing the contact portions of the terminals against contact pads on the chip carrier. As this occurs, the terminals provide a wiping action on the contact pad to ensure that positive electrical contact is effected. The housing may also cam the terminals outwardly to permit placement of the chip carrier in the recess under zero insertion force conditions.

    Abstract: Testsite system for use in an integrated circuit handler, the testsite system for testing plastic leaded chip carriers (PLCC), leadless chip carriers (LCC) and other IC packages. The testsite system utilizes a pocket in a socket which is moveable in a frame between a insert position for the IC and a test position for the IC. The testsite includes an ejector which operates against a first spring constant and a moveable pocket assembly which operates against a second spring constant. The moveable pocket in the socket provides for alignment between the IC package and the contact wires insuring positive electrical integrity. The spring action provides for ejection of an IC after test from the pocket by a spring actuated ejector, as well as the socket assembly returning to a home position while carrying the ejector and IC at the same time through the second spring action.
