Beyond Design: Microstrip Coplanar Waveguides

April 26, 2017 | Barry Olney, In-Circuit Design Pty. Ltd.

The classic coplanar waveguide (CPW) is formed by a microstrip conductor strip separated from a pair of ground planes pours, all on the same layer, affixed to a dielectric medium. In the ideal case, the thickness of the dielectric is infinite. But in practice, it is thick enough so that electromagnetic fields die out before they get out of the substrate. CPWs have been used for many years in RF and microwave design as they reduce radiation loss, at extremely high frequencies, compared to traditional microstrip. And now, as edge rates continue to rise, they are coming back into vogue. This month, I will look at how conformal field theory can be used to model the electromagnetic effects of microstrip coplanar waveguides.

TTM Shines a Light on Optical Interconnect

April 24, 2017 | I-Connect007

Are embedded optics on PCBs set to make a breakthrough in the upcoming years? According to Dr. Craig Davidson, VP of Corporate Technology at TTM, it might be closer than you’d expect. In a recent interview with the I-Connect007 team, Craig outlines TTM’s current pursuit of high-volume manufacturing lines able to deliver embedded optical interconnect, what that would mean for the PCB industry, and why he thinks there will be manufacturing production capability by 2020.

Obsessing over Conductor Surface Roughness: What’s the Effect on Dk?

April 12, 2017 | Bert Simonovich, Lamsim Enterprises Inc.

You know you have an obsession when you are flying six miles over Colorado and you look out the window at the beautiful scenery, and all you can think about is how the rocky mountain topology reminds you of conductor surface...

The Shaughnessy Report: We Have to be Marketers for our Industry

April 12, 2017 | Andy Shaughnessy, I-Connect007

IPC has been working for decades to get the PCB curriculum into colleges. But wait. Isn’t this our responsibility? It’s our industry; shouldn’t we see to it that our industry gets the respect it deserves, and that...
