EMI Shielding: What is it, and why it’s essential in electronic designs?

 244 total views

Whenever we turn on the switch or electric supply of an appliance, a magnetic field forms around it instantly. This energy can traverse into other electronic devices and act as Interference that could harm its working. This phenomenon, known as Electromagnetic Interference, is a common problem among electronics and appliances of all types. It can be something simple like your kitchen microwave to an elaborate system like a plane. Both these cases can lead to severe problems like system failure or data loss. That’s why electronic appliances and systems need barriers to protect against such Interference and ensure a smooth working for the device. EMI or Electromagnetic Interference Shielding is what helps engineers and product developers ensure efficient and perfect working, reflecting off any interference.

EMI Shielding gaskets are an example of a mechanical device that helps protect the devices. It is a barrier that shields both the source and the recipient of the Electromagnetic Interference. There are EMI Shielding specialists who provide these solutions for electronic items. Let’s look over some industries and everyday applications of EMI Shielding:

  • Railway and transportation systems need EMI Shielding devices that help prevent Interference and ensure smooth working. The interfering signals can harm the control systems and hamper train signaling. Both these scenarios could have drastic effects on schedules and safety.
  • Healthcare systems use electronics constantly. These electronic systems are crucial to the entire ecosystem, from a life support machine to computerized surgical devices. That’s why EMI Shielding is essential in Healthcare technologies that prevent any interference and harm to the devices.
  • You must have noticed that you have to turn off your mobile phones while flying. That’s because Electromagnetic Interference can damage the control systems. It can have drastic safety effects on the plane and lead to accidents.
  • Other everyday household items like your refrigerator, microwave, mobile phone, etc., need Electromagnetic Shielding too to prevent system failure.

Why is it essential?

EMI Shielding is crucial for both the common electronic systems in households and the elaborate ones. Let’s look over some drastic effects and damages that could emerge from a lack of EMI Shielding and how that could harm the systems:

  • Electromagnetic Interference can lead to short circuits and damage the appliance’s system. It’s because of a fault in power. Short-circuiting also causes long-term damage, and you may not be able to use it again.
  • Shielding gives a double benefit of preventing a device from interfering with others and protecting itself. Therefore, you should contact a Shielding specialist if you want to safeguard all of your electronic systems.
  • It prevents burnouts and blackouts for both the recipient and the source electronic system.

It’s pretty evident that every electronic device should have an EMI Shielding barrier to protect it from damage. Some specialists can help safeguard your existing products and also provide expertise during manufacturing. It’s better to outsource the work so that you can have an EMI Shielding team that tests out your electronic systems and provides the best solutions. So, find an expert now and begin the work.
