SIJ Technical Editor Eric Bogatin reviews two webinars: one on additively manufactured electronic circuits and one on automotive circuits.

The conventional PCB fabrication process for printed circuit boards is subtractive. Averatek recently introduced a new chemistry technology making semi additive circuit board fabrication more attractive for ultra fine line applications. SIJ’s technical editor, Eric Bogatin, takes a closer look.

Few topics are as fundamental in signal integrity and create as much confusion as signal bandwidth. What exactly does bandwidth refer to and what features in the time domain influence bandwidth: rise time or slew rate?

SIJ technical editor Eric Bogatin reflects on reflections…“Do corners in traces on circuit boards cause reflections? Of course, they do. Do the reflections cause problems and should you worry? … It depends.” Read on to see what he means.

There is an unsatisfied thirst by professional engineers to play with tools that give them a taste of the pro-level tools. Eric Bogatin makes his argument for low cost or “student level” equipment from tool vendors.

If you are missing your engineering tools, or would like to build up your home lab, or want to finally work on that hobby electronics project you’ve put off for the last five years, or you want to introduce your kids to the thrill of measuring or simulating, now would be a good time to consider our list of free or very low-cost hardware and software simulation tools.

Measuring low impedance components with a 2-port vector network analyzer (VNA) is an essential technique that typically requires a VNA that costs more than $20,000. In this article, see how the authors measured an MLCC using $500 and an open-source simulation tool.

Following best design practices for controlling EMI will increase your chance of success in your next design. But, sometimes knowing what not to do is just as important.

SIJ technical editor Eric Bogatin notes that there are some problems that occur over and over again across product families and applications. They have a handful of essential principles at their underlying root cause. In this blog, he explains that if we really understand these underlying principles, the root cause of the problems will be more apparent and their solutions closer to implement.
