Patent number: 7479794Abstract: A method and apparatus for constructing a probe card assembly is provided. A probe pin is inserted into an aperture of an inverted socket enclosure to cause a probe pin shoulder of the probe pin to make contact with an aperture shoulder of the aperture. An upper end of the probe pin protrudes from the aperture after the probe pin shoulder makes contact with the aperture shoulder. A compressible member is inserted into the aperture to position an upper end of the compressible member to make contact with a lower portion of the probe pin.

Patent number: 7393773Abstract: A method and apparatus for producing a substrate having a plurality of substantially co-planar bonding pads is provided. The substrate is employed in a probe apparatus used in wafer testing of wafer-mounted semiconductor integrated circuits. The bonding pads are formed by applying a plurality of bumps of electrically conductive material to a mounting surface of the substrate using a dispensing mechanism. The bumps are subsequently deformed into a plurality of substantially co-planar bonding pads using a flattening tool. The bonding pads provide a planar surface to which probes may be mounted, improving the accuracy and precision of positioning of tips of the probes.Type: GrantFiled: July 26, 2005Date of Patent: July 1, 2008Assignee: SV Probe Pte Ltd.Inventors: Edward L. Malantonio, Edward Laurent, Ilan Hanoon

Patent number: 7374811Abstract: A method for manufacturing a ceramic device is provided. The ceramic device comprises a ceramic layer. A polyimide layer is on the ceramic layer. The polyimide layer has disposed therein a plurality of copper vias. Each copper via is in physical contact with the ceramic layer. A plurality of pads are formed on the polyimide layer. Each of the plurality of pads is in physical contact with a copper via of the plurality of copper vias. In this way, the pads are supported by a continuous copper arrangement, thereby providing greater support for the probe pads than if the probe pads were supported by the polyimide layer, as the mechanical strength of polyimide layer is lower than the mechanical strength of copper.Type: GrantFiled: April 5, 2006Date of Patent: May 20, 2008Assignee: SV Probe Pte Ltd.Inventors: Chi Shih Chang, Bahadir Tunaboylu

Patent number: 7364461Abstract: Techniques for attaching a coaxial cable to an assembly are provided. A conductive layer is applied to a top and bottom surface of a first layer and the bottom surface of a second layer. An aperture is formed through the first layer. The first layer is affixed to the top of the second layer to form an assembly. A signal via and one or more shield vias are formed in the assembly. The signal via and the one or more shield vias, are covered with a conductive layer. The signal via is then electrically separated from the shield vias and the aperture. A stripped coaxial cable may then be inserted into the aperture so that the conductive core of the coaxial cable is electrically connected to the signal via but electrically isolated from the shield vias and aperture. The coaxial cable may then be secured to the assembly.Type: GrantFiled: February 28, 2007Date of Patent: April 29, 2008Assignee: SV Probe Pte. Ltd.Inventors: Gerald W. Back, Roger A. Sneddon

Patent number: 7182672Abstract: Methods are provided for shaping, maintaining the shape of, and cleaning a probe tip using a pad such as a multi-layer adhesive and abrasive pad. The multi-layer adhesive and abrasive pad may be formed from layers of adhesive material having abrasive particles in-between each layer. Using the pad, probe tips may be shaped as desired from an unfinished probe stock, substantially limiting the use of relatively expensive conventional machining operations. Further, the pad may also be used to maintain probe tips in a desired operating shape. Still further, the pad may be used to clean accumulated debris from the probe tip. Preferably, the maintenance and cleaning operations are performed on-line, with the probes operatively installed in connection with testing machinery.Type: GrantFiled: May 27, 2005Date of Patent: February 27, 2007Assignee: SV Probe Pte.

Patent number: 7173441Abstract: A interconnect assembly features a prefabricated interconnect structure metallurgically bonded to a terminal of a larger structure. Fabrication of the interconnect structure's independently and separate from the larger structure enables the use of economic mass fabrication techniques that are well-known for miniature scale sheet metal parts. During fabrication, positioning and attachment, each interconnect structure is combined with and/or held in a carrier structure from which it is separated after attachment to the terminal. The interconnect structure is configured such that an attachment tool may be brought into close proximity to the attachment interface between the interconnect structure and the terminal for a short and direct transmission of bonding energy onto the attachment interface. The attachment interface provides for an electrically conductive and a bending stress opposing mechanical connection between the interconnect structure and the terminal.Type: GrantFiled: October 12, 2004Date of Patent: February 6, 2007Assignee: SV Probe Pte., Ltd.Inventors: January Kister, David Beatson, Edward Laurent
