System-Level Grounding

Grounding is often viewed from separate points of view - safety, ESD, or EMI.  This article combines all these aspects together so that practitioners can address grounding at the factories and in the laboratories in a comprehensive way.

SCIF and Radio Frequency Secured Facility Design

Secure facility designs often comingle ICS/ICD-705 and NSA 94-106 design requirements, creating project confusion with significant design and cost implications. This article focuses on bringing some clarity to the differences between ICS/ICD-705 design guidance and NSA 94-106 performance requirements. The related secure facility design and construction process is also reviewed.

EMC Design Techniques for Electric Vehicle Powertrain Modules

This article presents the EMC design techniques for electric vehicle powertrain modules. High voltage EMC regulations for powertrain modules are reviewed first to help understand associated design challenges. The design techniques are then demonstrated in detail to help engineers design a module that will pass the EMC requirements in the test chamber.

System-Level Simulation Solutions for EOS and ESD

The electronic industry has embraced simulation to address several complex design challenges, but reliability is still mostly dealt with best design practices and tested with prototypes. In this article, we present how modeling and simulation approaches can help designers perform virtual prototyping and uncover reliability issues especially EOS/ESD before going for physical prototypes.

Fundamentals

RF Tech Tip: BNC Versus Threaded Connectors

The shielding performance of bayonet vs. threaded connectors is measured and some possibly surprising conclusions are drawn. Bayonet connectors – more useful than you might think.

Troubleshooting EMC Problems Like an MD

This article describes three troubleshooting methodologies doctors use to diagnose (troubleshoot) medical problems. These same techniques have proven useful in my own EMC consulting practice.

Continuing Your Professional Education in 2021

Traditionally, the start of a new year is a time when we reflect on the progress we’ve made during the year passed and set our goals for the new year. We’ve queried training resources in our industry to provide you with an overview of free or affordable solutions to meet your training goals in 2021.

Standards and Compliance

Product Liability Marketing Defects

The way you market your product can turn an otherwise safely designed product into an unsafe product that causes injury and creates liability for the manufacturer and product seller.
