How to Ground Electronics

When it comes to mitigating the damaging impact of electromagnetic interference (EMI), device manufacturers should look at design considerations from multiple angles as early in the process as possible to avoid last-minute modifications, which can add unnecessary expense and delays. Learn more about how to reduce EMI and four areas engineers should examine as they consider how to prevent electromagnetic interference in products and devices. 

The Basics: How to Prevent, Stop, and Reduce Electromagnetic Interference

For any company who manufactures or works with electronics, understanding how to reduce electromagnetic interference (EMI) is a chief concern. By becoming more aware of what causes EMI and how to avoid it, companies will be well-positioned to deliver high-performing products that aren’t degraded by the effects of EMI. 

Understanding Electromagnetic Interference (EMI) Reduction

EMI is unwanted noise or interference within an electrical circuit. These incidences, which occur as a result of electromagnetic fields from a variety of natural and manmade sources, can impair system performance or even stop it from operating altogether. The potential impacts of EMI become particularly serious and potentially even life-threatening in medical devices such as pacemakers or modern vehicles equipped with advanced driver assistance systems (ADAS). It’s important for producers to consider potential EMI interactions so they can be mitigated before a problem occurs. 

How You Can Prevent and Avoid EMI

If you’re wondering how to avoid electromagnetic interference, the best offense is a good defense. Look at design considerations from multiple angles as early in the process as possible to avoid last-minute modifications, which can add unnecessary expense and delays.

Here are four areas engineers should consider as they investigate how to prevent electromagnetic interference in products and devices:

  1. Electrical: What are the requirements that the electrical system must meet? Are there any industry or governing body requirements that should be taken into consideration, such as those set forth by the Federal Communications Commission, the military, or the Federal Aviation Association?
  2. Physical and mechanical: How and where will the device or component be used? Is there any design flexibility, and if so, how much?
  3. Environmental: What elements or physical conditions must the device or component withstand? For instance, will it be used on a beach where it will be exposed to salt and humidity, or in the winter where it could face snow and cold temperatures? Are there any environmental restrictions, such as chemicals that must be avoided during the manufacturing process?
  4. Commercial: Will the device be a single component or part of an assembly? What is the total cost of ownership, and will the total life span be for a few months, a few years, or longer?

By having a thorough understanding of a device’s design requirements, companies can choose appropriate products that will mitigate the potential impacts of EMI.
