How is EMC achieved?

Most EMC is achieved through good circuit design. The EMI created by one part of a circuit is nullified by engineering another part of the circuit to make an opposing EMI, which when combined cancels the EMI out. Such engineering not only eliminates the creation of EMI, but it also makes the circuit resistant to external sources of EMI.

One of the most basic engineering techniques demonstrating this wave cancelling technique is twisted pair wiring, where one wire is run in opposite direction to another, and they are twisted together, so that the EMI produced by one wire is cancelled by the EMI produced by the other.

About Dr Lee Hitchens

Dr Hitchens has been working in the electronics industry and the area of conformal coatings for over 25 years in various areas including sales and technical support. He has also been training people for almost the same amount of time in all areas of conformal coating whether that is materials & equipment selection, process development or troubleshooting to help them solve their particular problem. Recently, he decided that the industry needed a specific place where all of the useful knowledge on conformal coatings could be collated for users to find easily and use in their own production process. So, Nexus was born and he began the Nexus eBook project.
