Megtron6 Handle Electromagnetic Interference EMI
Electromagnetic interference EMI is all around us, from the static noise that interferes with your radio to the buzz you experience when talking on your cell phone near audio equipment. It’s also one of the biggest challenges faced by electronic designers when putting together circuit boards for a wide range of applications. Without proper design techniques, EMI can negatively impact the functioning of an entire system.
It takes a lot of theoretical knowledge and hands-on experience to fully grasp the physics behind electromagnetic interference, so we won’t attempt to cover it in this article. However, there are a few things to keep in mind when designing your circuit board that will help mitigate EMI issues. First, be sure to account for the return current path in your layout. This is particularly important with high-side current-sense devices that monitor solenoids or other inductive loads. The circuitry in these devices must be designed to not generate or propagate EMI, and it’s critical to use components with built-in EMI filtering.
The second thing to keep in mind is to avoid unintended resonances and parasitic elements, which are often caused by poor component placement or a lack of physical space. In addition, high-frequency switching (e.g., at 10s of kilohertz) can generate substantial EMI and is more problematic than low-frequency switching. It’s essential to understand the underlying physics behind these issues, and the best way to do this is by using internal EMI filters and properly placing and routing your components.

Lastly, be sure to schedule EMI tests during your design process and review the results. These tests will help you pinpoint EMI sources and address them early in the design phase. This will reduce the likelihood of an EMI problem during testing and operation, and it will ensure your device meets EMC standards right away.
Megtron6 designs high-quality PCBs that are resistant to EMI and other electromagnetic interference. We incorporate internal EMI suppression filters and best practices throughout the entire production process, including component placement and routing. We also conduct thorough EMI tests, including conducted and radiated emissions testing, to ensure our products meet all applicable EMI requirements.
With increasing complexity in medical, military, and aerospace equipment and vehicles, EMI issues have become increasingly prevalent. This is because EM frequencies are getting higher and wavelengths are getting smaller, making it challenging to contain and suppress unwanted interference. By using components with internal EMI suppression and by following best design practices, megtron6 helps our customers overcome EMI problems and build robust, reliable electronic systems.

Flex PCBs often require custom designs, and a good quick-turn manufacturer should be able to assist with design optimization for flexibility, manufacturability, and cost-effectiveness. They should provide design support, including checking your design files for manufacturability and offering suggestions for improvements, such as reducing the risk of signal interference or optimizing layer stacking for flexibility.
