EMI Shielding: The What, Why, and How!
Did you know that approximately 350 electrical-related deaths occur on the job in the US every year? Electronics are everywhere. When it comes to industry, they are a vital part of how everything works.
This creates a protection challenge. These circuits and systems would be vulnerable to interference if a shield wasn’t used to help protect them.
EMI shielding is the process by which electronics are protected from interference. But what does EM shielding do? How does it work? Why do I need it?
We’re glad you asked. Not quite sure? Continue reading for the low down on EMI shielding.
What is EMI Shielding?
EMI shielding is a form of protective shielding used to reduce the electromagnetic interference (EMI) that can be emitted by electronic devices. This shielding works by absorbing or reflecting the EMI waves so that they can not cause disruption to other devices or systems. It can help protect against the transfer of EMI from one device to another, which may cause interference or even complete failure of the device or system.
EMI shielding also helps to protect against human exposure to EMI radiation, which can be harmful over extended periods of time. It is typically used in electronics, aerospace, and medical fields but is becoming increasingly common in industrial settings as well.
Why is EMI Shielding Important?
EMI shielding is important because it helps to protect electronic systems from electromagnetic interference. This interference can cause radio signal loss, data corruption, and even complete device failure. By shielding these sensitive components from these dangerous signals, the equipment can remain stable and reliable even in areas with a high level of electromagnetic activity.
EMI shielding also helps to ensure that the devices do not interfere with other electronic equipment, thus allowing for more efficient operation. Additionally, it can help to reduce the effect of electronic noise, which can often interfere with the operation of other sensitive components. In summary, EMI shielding is a critical component for the successful operation of electronic systems.
How Does EMI Shielding Work?
EMI shielding is a process used to protect electronic equipment from electromagnetic interference, or EMI. It works by creating a barrier between the electronic components and the electromagnetic waves, which can interfere with them.
These EMI shielding materials are typically made up of a metal foil, usually copper or aluminum, by dip brazing that is wrapped around the device. This material conducts the EM energy away from the circuitry, protecting it from interference.
The shielding material can also be combined with absorbers, such as absorptive foam, to absorb some of the energy and prevent it from reflecting back into the circuitry. Other technologies are also used to reduce interference, such as filters and ground planes, but EMI shielding is the most effective means of reducing EMI.
Importance of EMI Shielding
EMI shielding is an essential tool for protecting products and components from the impact of unwanted forms of electromagnetic interference. Through a variety of materials, techniques, and construction methods, it is possible to reduce the risk of damaging electromagnetic energy.
