VRPW-10-40 Design Insights from Electromagnetic Analysis of Interconnects

A Front Range Signal Integrity Lecture, presented by Dr. Yuriy Shlepnev, President and Founder of Simberian Electromagnetic Solutions

Live, Oct 3, 2013, Longmont, CO

Yuriy offers a number of examples where an EM analysis provides design guidance. He starts with materials analysis and shows how to model and measure the frequency dependent material properties of laminates. This includes the losses from copper surface texture.

He shares the analysis he did on the additional losses of nickel plated traces such as under gold. The results are very surprising. He shows the impact from the slightly higher and frequency dependent permeability of nickel and the higher resistivity.

He then looks at a variety of physical structures which cause discontinuities and how their design can be optimized with a 3D field solver. These includes bends, compensation lengths, DC blocking capacitors and via to via cross talk.
