EMI failures can happen due to small, innocent mistakes. One specific issue, as shown in the picture, is the lack of return reference...

This picture helped me bridge the gap between electronic theory and PCB design for EMC in practice. One of the hardest things I found...

Switched Mode Power Supply - EMI will catch you when you least expect it! It's always about them: Common-mode current! They always find a...

One of the final tests for your electronic design before it becomes available on the market will be the conducted emissions test....

Here are several issues that can arise in your PCB Design if these things are not well taken care of. My hope is to help you see these...

This is why many PCB designs and electronic products fail EMC tests! Oversimplified? Maybe not. In the majority of cases, the problem is...

If you are failing the EMC test in Radiated Emissions, this will help you see why: The formula you see here describes the radiated...

Looks like an innocent mistake, but this can cause a great deal of EMI troubles. To put it simply, think about your chassis as acting...

In designing for EMC, details matter. A lot! A simple example is ribbon cables. Most often, to save on costs (only apparent), we cut down...

The first thing I look at when a client's project fails EMI: The Stackup! I like to think about the stackup as the foundation of a...

One of the most problematic EMI events for your product! It won't matter if you have a metal enclosure or a plastic enclosure; you always...

One of the toughest EMC issues you are likely to encounter when designing printed circuit boards is managing radiations from common mode...

When your Printed Circuit Board (PCB) fails EMC tests, often the problem is not one big issue, but the compounding of many poor design...

One of the classic ESD misconceptions is thinking: "We won't have Electrostatic Discharge problems; we connected the chassis to the...

Good EMC results start with a well-chosen stackup. Is it that simple? Almost. I like to think about EMC as the test which measures how...

This is one of the reasons why many hardware designers fail to pass EMC tests. This is also one of the hardest concepts I struggled with...

Back when I started designing PCBs I heard it was pretty common to use power planes as Return Reference Planes (RRP), and I still see...

If current always flows in loops, how is it possible for a signal to propagate if the signal has not yet reached the load and the...

Crosstalk can not only be a signal integrity problem, but it can also become a very painful EMI problem if noise couples from a trace to...
