Conformal Conductive Coating and EMI Shielding
This is a diverse and promising space. In one manifestation, spray-on inks are targeting package-level EMI shielding. Here, they hope to displace sputtering, the incumbent, which benefits from sunk CapEx and lower material consumption costs. They offer low CapEx production in atmospheric conditions and better conformal coverage. Others are developing inkjet printing solutions, … [Read more...]
Be Careful with Low Cost/Quality Common Mode Chokes ….
Dear readers, I have been really busy working in training and EMI troubleshooting in the past months. I am happy to be here again with a new post. This month we will see a topic from a real-world situation - very interesting - for electronic designers working in conducted emissions problems. In one of the projects I was involved with several weeks ago, a product was … [Read more...]
Electrostatic Discharge (ESD) in Electro-Optic Devices
Many electronic components used in highly technological devices can be damaged or degraded by sudden electrostatic discharges, known by the term Electrostatic Discharge (ESD). Components such as transistors, diodes, laser diodes, electro-optical devices, and a variety of integrated circuits are all sensitive to electrostatic discharge. Many manufacturers are increasingly … [Read more...]
EMC Laboratory Selection Audit Items
Introduction This blog will provide the reader with an introduction to some of the items that need to be looked at when auditing an EMC laboratory with an eye to placing them on your company’s approved lab list. This is not an in-depth look at each item but is based on my experiences auditing laboratories (both in-house and 3rd party) over a number of years. Key … [Read more...]

Unwanted conductive and radiative emissions can be … [Read more...]
Digging Deep into the RF Spectrum: New CRFS Toolkit for Forensic Spectrum Analysis
Cambridge, UK: CRFS, an RF technology company, has today launched a new software tool called RFeye DeepView. DeepView is unique in two key ways. Firstly, it allows the user to analyze the RF spectrum in precise detail, to discover signals of interest that might be intermittent or hidden in the noise. It also enables the user to analyze vast data sets with unprecedented ease and … [Read more...]

Knowles PD10730
“The rate of component obsolescence has increased over the last 15 years”, says Steve Hopwood, Senior Application Engineer at Knowles Precision Devices (KPD). “OCMs are discontinuing more part numbers per year for a variety of reasons, including manufacturing changes, changes in die dimensions and other technology changes.” The increase in the number of EOL notices over … [Read more...]
EMI Troubleshooting with Real-Time Spectrum Analyzers
The latest tool for serious EMI troubleshooting or debugging has become the real-time (RT) spectrum analyzer. Because manufacturing costs have been decreasing, some RT analyzers are becoming more affordable than ever. In this article, I’ll show you the advantages in using RT analysis for observing and troubleshooting unusual EMI. INTRODUCTION First, let’s review the … [Read more...]
