This column discusses "wordless" safety labels, which use symbols and hazard severity panels without text. It explores their benefits, limitations, and implementation considerations, emphasizing the importance of balancing complete information with clear communication in product safety warnings.

This article explains how to use a Smith Chart to determine the voltage standing wave ratio (VSWR).

Standards continuously evolve, and EOS/ESD Association, Inc. standards are no different. The ESDA is always striving to achieve the highest quality standards.

Explore the impact of the return path impedance and the return current level on common-impedance coupling between circuits. The measurements presented were performed on a custom PCB containing audio, video, and high-current circuitry, where the return paths for each circuit were selectively shared with other circuits.

Humidity control in relation to an ESD control program continues to be misunderstood across the industry. Humidity does help in the reduction of charge accumulation, but it does not control charge accumulation to reduce the risk to sensitive items.

This article discusses using the reciprocity theorem in EMC troubleshooting, particularly for immunity issues. It describes a case study involving a smart meter and demonstrates how emission measurements can help identify susceptibility problems, highlighting the usefulness of walkie-talkies in testing.

In this article, we investigate the impact of a guard trace on crosstalk reduction and present measurements taken with the latest‑generation PCB, both in time and frequency domains.

This article is the first of a two-article series devoted to the topic of crosstalk between PCB traces. In Part 1 of the series, we vary circuit topology, i.e., the distance between traces and the distance to the ground plane.

The article discusses ESD protection challenges for RF switches in SOI technology. It examines the self-protection mechanism, proposes a behavioral model to simulate ESD response more accurately, and explores predicting failure current levels critical for reliable ESD design.

We are proud to carry on the tradition of sharing Banana Skins for the purpose of promoting education for EMI/EMC engineers.
