Fixing EMC problems by applying good EMC design techniques
It is always very much better to design EMC in from the start of any new project. Not only does it achieve EMC compliance in the quickest time and with the least cost, it also improves signal integrity (SI) and power integrity (PI), reduces warranty costs, and reduces the time it takes to get to market (even when compared with the time it would normally take if EMC compliance was not done).
In other words: good EMC design techniques help achieve financial success, even when EMC compliance is not required.
However, good EMC design is not generally taught in University Degree, Masters, or Doctorate courses, so each year sees a new intake of design engineers ready to make the same very costly and time-consuming mistakes as their predecessors.

EMC Standards is a world-leading resource for all things EMC and EMI related. Our website is packed full of both free and paid-for content, including:
- Online quiz
- Training quiz
- And much more!
Electromagnetic Engineering (EMgineering) is the basis for proven good design practices for signal integrity (SI), power integrity (PI), and the control of EMI emissions and immunity (EMC).
Our aim is to help people learn how to more quickly and cost-effectively design and manufacture electronic equipment (products, systems, installations, etc.) to meet functional (i.e. SI/PI) specifications and conform to EMC standards, directives and other requirements.
Such equipment should benefit from reduced warranty costs and financial risks, whilst improving uptime, competitiveness and profitability.
We also cover basic good electrical safety engineering; and the Risk Management of Electromagnetic Disturbances / EMI, whether for Functional Safety or other types of risk.Join EMC standards TODAY!
