The Reports of Copper’s Death May Be Exaggerated

About 150 years ago the first stable transatlantic cable was laid and messages were sent between Ireland and Newfound­land over copper. The data rate on this cable was not even 1 bit/sec, it was 0.1 bit/sec. Concerns over the cable reliabil­ity and the slow data rate led some to believe copper was doomed as a communication media for these long cables.

Utilizing Fine Line PCBs with High Density BGAs

With the recent introduction of the Averatek Semi-Additive Process (A-SAP) process, linewidths under 1 mil are possible using the same fabrication processing line as for traditional 4 mil wide lines. This opens up the possibility of using narrower traces in the BGA escape region than in long-path routing regions. However, using this routing architecture means the narrower traces in the BGA escape field are at a higher impedance than the wider, 50 ohm traces in the routing region. So, how long can these traces be before the impedance mismatch is a problem? The authors of this piece propose an analysis methodology to find out.

Eight Tips on Giving a Presentation

Now that I am teaching full time and have a number of undergraduate and graduate students doing weekly project reviews, I listen to more presentations than I give. I find myself giving the same feedback over and over again. So, I thought I would share my eight most common comments and tips to engineers giving presentations.

Ansys Releases Free Electronics Desktop Student Product Download

In the January 2021 print issue and the April 2021 online issue of the Signal Integrity Journal, I wrote an editorial in which I threw down a gauntlet to tool vendors to offer low cost or free versions of their tools to help engineers accelerate up the learning curve. Ansys picked up that gauntlet and now offers a free version of their industry standard electromagnetic simulator suite, Electronics Desktop.
