I would like to join Zhiping and invite everyone to the SI sessions at EMC symposium in Long Beach, CA. There will be some interesting presentations there - technical program is at http://emc2011.org/program/technical-program/. In particular, Scott McMorrow from Teraspeed Consulting Group and I will present a new model for analysis of interconnects plated with nickel (ENIG) and validated up to 40 GHz (Aug. 17, 3:30 pm). We will explain the mystery of resonances between 2 and 3 GHz that were experimentally observed in nickel-plated interconnects in multiple papers. The subject has been discussed at this forum some time ago. Together with Chudy Nwachukwu from Isola, we will present a new model for analysis of interconnects with rough conductors (Aug. 17, 2:30 pm). We will provide numerical and experimental evidence that some types of rough copper on PCBs increase capacitance of the traces and essentially the effective dielectric constant in addition to commonly observed increase of attenuation. The observed increase in capacitance was 5%-10% over all frequencies. It is simulated and simply explained as the result of additional charges on sharp spikes on the rough copper surfaces (singular surface effect). Please join us for more details and discussion. The papers and presentations will be also available on request after the symposium in case if you will not be able to attend.

We have a special signal integrity session on high-speed link (Full Channel Characterization and Link Path Analysis for High-Speed Interconnects) with six distinguished speakers from the industry. The paper titles and speaker bios can be found at http://emclab.mst.edu/documents/EMC2011_Special_Session_Ads.pdf Beside our special session, Dr. Howard Johnson will have another special session on signal integrity and there are many other good sessions on signal integrity and EMC at this conference. It should be a great learning event. For more detailed info, please visit conference official web site: http://emc2011.org/. You are welcome to attend our session and other events at the conference. Please feel free to forward it to anyone who might be interested in attending.
