  • Patent number: 7321233
    Abstract: An interconnect assembly for evaluating a probe measurement network includes a base, respective inner and outer probing areas in mutually coplanar relationship on the upper face of the base, a reference junction, and a high-frequency transmission structure connecting the probing areas and the reference junction so that high-frequency signals can be uniformly transferred therebetween. A preferred method for evaluating the signal channels of the network includes connecting a reference unit to the reference junction and successively positioning each device-probing end that corresponds to a signal channel of interest on the inner probing area.

  • Patent number: 7109731
    Abstract: A membrane probing assembly includes a support element having an incompressible forward support tiltably coupled to a rearward base and a membrane assembly, formed of polyimide layers, with its central region interconnected to the support by an elastomeric layer. Flexible traces form data/signal lines to contacts on the central region. Each contact comprises a rigid beam and a bump located in off-centered location on the beam, which bump includes a contacting portion. After initial touchdown of these contacting portions, further over-travel of the pads causes each beam to independently tilt locally so that different portions of each beam move different distances relative to the support thus driving each contact into lateral scrubbing movement across the pad thereby clearing away oxide buildup. The elastomeric member backed by the incompressible support ensures sufficient scrub pressure and reliable tilt recovery of each contact without mechanical straining of the beam.

  • Patent number: 6803779
    Abstract: An interconnect assembly for evaluating a probe measurement network includes a base, respective inner and outer probing areas in mutually coplanar relationship on the upper face of the base, a reference junction, and a high-frequency transmission structure connecting the probing areas and the reference junction so that high-frequency signals can be uniformly transferred therebetween despite, for example, variable positioning of the device-probing ends of the network on the probing areas. A preferred method for evaluating the signal channels of the network includes connecting a reference unit to the reference junction and successively positioning each device-probing end that corresponds to a signal channel of interest on the inner probing area.
