Patent number: 7885781Abstract: Methods, systems, and computer program products are disclosed for acquiring test data from an electronic circuit by mounting a probe adjacent to a capture point on an electronic circuit board, capturing by the probe an electronic signal of the electronic circuit, digitizing by the probe the captured signal, and transmitting by the probe the digitized signal from the probe through a data communications connection to a remote device. Acquiring test data from an electronic circuit also includes storing by the probe the digitized signal in the probe. Acquiring test data from an electronic circuit may include processing by the probe the digitized signal. Acquiring test data from an electronic circuit also may include synchronizing acquisition of test data by the probe with acquisition of test data by one or more other probes.Type: GrantFiled: July 2, 2008Date of Patent: February 8, 2011Assignee: International Business Machines CorporationInventors: Todd A.

Publication number: 20090085155Abstract: A method of package-to-board impedance matching for high speed integrated circuits (ICs). Multiple solder balls are attached to an IC package. The IC package includes multiple conductive interconnect layers, where one of the conductive interconnect layers is coupled to one or more of the multiple solder balls. Multiple vias are coupled between different conductive interconnect layers. An inductive element is coupled between an interconnect lead and a via land in the conductive interconnect layer within the IC package. The physical layout dimensions of the inductive element are configured such that the inductive element provides an inductance value that is sufficient to offset a parasitic capacitance provided by the conductive interconnect layers and the solder balls. The inductive element may be a bond wire, an inductive interconnect, or a spiral interconnect.Type: ApplicationFiled: September 28, 2007Publication date: April 2, 2009Inventors: Mark J. Bailey, Todd A. Cannon, Haitian Hu, Nanju Na, Katsuyuki Yonehara, Deborah E. Zwitter

Publication number: 20060288570Abstract: A method and structures are provided for implementing customizable dielectric printed circuit card traces. A void is defined near selected signal traces. The void is then filled with a dielectric material having a predefined dielectric property. The dielectric material is selected to alter at least one predefined electrical property of the selected signal traces, such as, coupling, propagation delay and attenuation. In one embodiment, an outer layer of a printed circuit card includes a plurality of signal traces and a mating circuit card layer including a plurality of matching signal traces is attached to the outer layer of the printed circuit card to create a cavity near selected signal traces. The cavity is filled with the selected dielectric material. In another embodiment, dielectric material is selectively removed near signal traces on an outer layer of the printed circuit card to define a void near selected signal traces.Type: ApplicationFiled: August 31, 2006Publication date: December 28, 2006Inventors: Todd Cannon, William Csongradi, Benjamin Fox, Roger Gravrok, Mark Hoffmeyer, David Pease, Ryan Schlichting
