Most Important PCB Layer Stack-up Considerations That Achieve Optimal EMC Performance

There are many books and other reference materials available that describe proper printed circuit board (PCB) layer stack-ups to achieve EMC compliance (see References and Further Reading section located at the... Read More...

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.

Evaluation of EMC Emissions and Ground Techniques on 1- and 2-layer PCBs with Power Converters

This is the 10th and the final article in a series of articles devoted to the design, test, and EMC emissions evaluation of 1- and 2-layer PCBs that contain AC/DC and/or DC/DC converters and employ different ground techniques.

Evaluation of EMC Emissions and Ground Techniques on 1- and 2-layer PCBs with Power Converters

We continue to focus on the AC/DC power converter board (2-layer PCB). We evaluate the implementation of several EMC countermeasures and present the conducted and radiated emissions results performed according to the CFR Title 47, Part 15, Subpart B, Class B.
