What Every Electronics Engineer Needs to Know About: Working with EMC Test Labs
Choosing an EMC test lab to work with is one of the most important decisions any electronics design engineer or product developer has to make.
Capacitor Technologies Used in Filtering
Although understanding each capacitor type and behavior is daunting and difficult to memorize, it is prudent that every aspiring engineer and technician involved in design for EMC at least have a rudimentary understanding of what capacitor technologies are available.
RF Absorption Loss of Shielding Materials
To determine a shielding material’s potential absorption loss capability, you must first know the frequency or frequencies of concern and, second, what shield materials you have available.
Human Body Model ESD Testing
To provide in-depth coverage of ESD testing methods, in this article, we look at another type of ESD testing based on the “Human Body Model” (HBM) method of ESD testing.
Quarter-Wavelength Impedance Matching Networks
This article describes a loss-less impedance matching technique that does not require the use of discrete components but instead uses cables or printed circuit board (PCB) traces, i.e., distributed elements or transmission lines.
What To Do When Your Product Must Comply with Conflicting Requirements
As a compliance engineering professional, you may encounter situations when you must consider how multiple and often conflicting requirements apply to your product and how to deal with them effectively.
Signal Integrity Versus EMC
This article addresses two very common questions involving two interrelated and specialized sub-fields within the realm of compliance engineering.
Use of Ferrites in PCB Reference Planes
Should the reference (i.e., ground) plane be split into two separate sections and a ferrite bead installed between them to prevent unwanted radio frequency emissions? Let’s examine why this practice is not a good idea and should be avoided at all costs.
Post-layout Signal Integrity/Power Integrity Simulation Software Expectations
Discover the most important post-layout elements when selecting a SI/PI software simulation package.
How to Select Absorbing Materials for Retrofitting
If you think you’re ever going to need to use flexible RF absorber sheets to help your product pass emissions, even at some later date, it might be a good idea to have already identified and obtained the material and have characterized its insertion-loss performance.
