The EMC 2014 Symposium will be shedding light on new technology and helping you to stay abreast of current EMC testing and engineering. New in 2014 will be an embedded conference for signal and power integrity. Plan ahead to join us August 3-8, 2014 in the City of Oaks - Raleigh, North Carolina, for a week of learning, collaboration and networking with industry peers. The Symposium has something for everybody; from rookie to veteran, across all industries and academia.
Isola's Chudy Nwachukwu will present a paper entitled, "Modelling Jitter Induced by Fibre Weave Effect in PCB dielectrics" on Thursday, August 7th at 9:00 AM.
Abstract: Dielectric properties of Printed Circuit Board (PCB) glass weave re-enforcement can differ greatly from the properties of the resin matrix due to processes inherent in the engineering of dielectric substrates. This inhomogeneity can contribute to increases in skew and deterministic jitter at data rates of 10 Gbps and higher for paired transmission lines routed on typical PCB materials. This paper proposes a new model for accurately characterizing the glass weave-induced skew and jitter in PCB substrates. This new model will be used to predict the package-level performance of existing and next-generation skew mitigating laminate materials. The model provides guidance for PCB material selection on the basis of skew/jitter estimates for the corner cases.
