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.

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.

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.
