At DesignCon 2004, Winchester Electronics and Interconnect Technologies, business units of Northrop Grumman Corp. (Los Angeles, CA), and Xilinx Inc. (San Jose, CA) demonstrated the world's first implementation of a fully functioning 10 Gbps backplane reference design, manufactured using Winchester's SIP1000 I-Platform Passive Interconnect Technology, Interconnect Technologies' printed circuit board design and fabrication expertise and Xilinx Virtex-II Pro X field programmable gate arrys (FPGAs), and tested using Agilent 10 Gbps test and measurement equipment. Consistent with the input/output technology detailed in the UXPi standard, the companies demonstrated that 10 Gbps backplanes can be manufactured with off-the-shelf products and services available today.
"The inherent scalability and cost advantages of high-speed serial make this technology imperative for current and next-generation telecommunications, networking and storage applications," said Erich Goetting, vice president and general manager of the Advanced Product Group at Xilinx. "Today's demonstration proves that technology continues to push the envelope; backplanes can be built today that support 5G, 6.25G and 10G serial rates, allowing tomorrow's backplanes to be built and deployed today."
Michael P. Driscoll, president, Winchester Electronics, said, "The passive channel technology we are demonstrating at DesignCon 2004 will serve as a solid base upon which transceiver technologies for data rates of 20 Gbps and beyond will be built.The days of just selling connectors and printed circuit boards are gone and the days of selling channels have arrived. The reference design demonstrated proves that 10 Gbps in copper is a reality today."
The platform is a true interconnect platform designed to enable 10 Gbps+ serial data transmission in copper backplanes without the need for active equalization techniques. Conceived as a passive system-level interconnect, the platform seeks to reset the balance between the passive and active elements in what have become known as active interconnect systems by delivering a revolutionary new interconnect technology architecture that provides solutions for ultra high-speed, high-density differential applications.
Northrop Grumman Winchester Electronics is a provider of high-speed, high-bandwidth interconnect products, including board-to-board connectors, RF connectors, cable assemblies and power interconnects. Northrop Grumman Interconnect Technologies designs and manufactures electrical and electro-optical printed circuit boards and backpanel assemblies.
The announcement represents a major milestone in the Xilinx Serial Tsunami initiative, designed to accelerate the industry move from parallel to serial I/O technology by delivering next-generation connectivity solutions that meet bandwidth requirements from 3.125 Gbps today to 10.3125 Gbps and beyond.

Beginning March 1, 2004, Wolf Electronix (Orem, UT), an electronics contract manufacturer (CM), will begin assembly of surface-mount and through-hole components with complete box-build capabilities—including cable harnessing and testing—in Mexicali, Mexico. The 30,000 sq. ft. facility will house the surface-mount and through-hole equipment, along with automated optical inspection (AOI) machinery.
The expansion allows Wolf to reduce labor costs up to 50% on low-mix high-run projects; thus proving an alternative for U.S. companies desiring to keep work in North America while remaining competitive. For the complete box-build, an estimated savings of up to 20% could apply.
Wolf was the first CM in the state of Utah to be awarded an ISO 9002 registration for their quality management system and currently have 9001:2000 registrations at the Utah and Colorado facilities. Wolf now is the first CM headquartered in the state of Utah to expand into Mexico.
"We desire all companies in the U.S. working with a CM to have the overseas labor rates while enjoying closer proximity and ease of communication," said Jim Trent Jr., president of Wolf. " I encourage every company to have the project quoted and compare."
Channels are already in place to facilitate the flow of product from the Mexico facility.

The electronics interconnection group at National Physical Laboratory (NPL, Teddington, UK) is making progress in its current research projects.
The use of AC signals instead of DC in surface monitoring of process residues, such as flux, is yielding startling results. The new methods, dubbed surface insulation impedance (SII), show that some fluxes appear to provide variations in loss of signal in an AC environment orders of magnitude higher than predicted by traditional DC surface insulation resistance (SIR) techniques. Ongoing work continues to validate the findings, which could have important implications for AC circuit reliability. For more information, contact: alan.brewin@npl.co.uk.
Over 170,000 electronic component joints have been built with two isotropic conductive adhesive materials at NPL. These samples are now in seven different accelerated environments comprising damp heat, dry heat and thermal cycling. The next steps will involve analysis of joint conductivity, shear and drop test data to compare the reliability performance of the adhesive joints to that achievable with solder. Contact martin.wickham@ntlworld.com for further information.
Work to improve solderability wetting balance tests by including a pre-heating process for the component is showing significant rewards. The use of pre-heat with focused IR energy allows for a lower solder globule or bath temperature and better representation in the test to the reality of wave of reflow soldering conditions. The improved method is likely to reward users with a better prediction of defect rates if parts are used in production. For more information, contact: alan.brewin@npl.co.uk.
