Patent number: 6529021Abstract: A self scrubbing buckling beam contactor for contacting an array of pads positioned on a device under test is described. The contactor consists of three insulating dies: a top, an offset and a lower die separated from each other by an insulated spacer of variable thickness. Each die is provided with holes.

Patent number: 6429672Abstract: A bed-of-nails type or needle-card type test probe has clusters of parallel buckling beams arranged in a spaced arrangement. The buckling beams are arranged and electrically connected within a cluster so that a contaminant, which may be on the device being tested, does not reduce the accuracy of the test measurements. In particular, the spacing of the buckling beams is such that multiple buckling beams are capable of contacting a single feature on an electronics package to be tested. The buckling beams deflect independently of each other in response to compressive force, and the buckling beams within a cluster are electrically connected in parallel to each other to define redundant, independent conductive paths through the buckling beams. In this way, if a contaminant prevents one of the buckling beams of the cluster from making electrical contact with the feature to be tested, the other one or more of the buckling beams of the cluster will make the required electrical connection.Type: GrantFiled: June 30, 1998Date of Patent: August 6, 2002Assignee: International Business Machines CorporationInventors: Robert N. Wiggin, Yuet-Ying Yu

Patent number: 6404211Abstract: A buckling beam probe assembly and a process to make the assembly using insulated metal to hold the vertical beam probe wires. The buckling beam probe assembly electrically connects a test apparatus with contact pads on the surface of a device to be tested. The assembly is formed with a plurality of buckling beam wires each having a head, a body, and a tail. Each of the beam wires is pressed vertically onto the contact pads and buckles laterally to adapt to height differences of the contact pads caused by irregularities on the surface of the device to be tested. A top plate has a first plurality of apertures receiving the heads of the plurality of buckling beam wires. A bottom plate has a second plurality of apertures receiving the tails of the plurality of buckling beams wires. A plurality of intermediate metal sections are positioned between the top plate and the bottom plate.Type: GrantFiled: February 11, 1999Date of Patent: June 11, 2002Assignee: International Business Machines CorporationInventors: Harvey C.

Patent number: 6385609Abstract: A system and methods are provided for collecting, analyzing, and reporting data supplied on the report data stream of an electronic switching system or other generator of a report or log data stream or file. Local data storage facilities are provided to receive and store report data stream information for one or more switches. A centralized data storage and analysis facility receives the data collected by the local facilities. A parser parses the collected report data to select and reformat report items of interest according to predefined selection triggers. A post processing facility includes pattern identification and pattern classification components. The pattern identification component reads the parsed, selected report items and extracts a pattern comprising the selection triggers and function call addresses associated with each event. The pattern classification component determines whether the identified pattern for each event is old or newly encountered.Type: GrantFiled: April 23, 1999Date of Patent: May 7, 2002Assignee: Lucent Technologies Inc.Inventors: Alvin Barshefsky, Shao-Kuang Hu, Scott Douglas Olmstead, Kirk K.
