Is EMI Dangerous for Electronics?

EMI Shielding

How much thought have you put into the importance of EMI shielding for your new electronic device or equipment? The technological world we live in is expanding rapidly. Ensuring that systems, equipment, and devices function optimally, EMI RFI shielding is one of the more important design considerations engineers need to make. Many find that their EMI shielding isn't adequate too late in the production process. In a situation like this, it ends up costing a great deal of time and money to rectify. What is EMI shielding, and how does it work?

EMI shielding is a manufacturing technique that utilizes highly specific materials to protect signals from disruption from external electromagnetic interference or signals. The secondary function of an EMI shield is to prevent EMI that is generated within the device from escaping and interfering with surrounding components and electronics. For instance, modern cars contain many computer chips and electronic devices, and for them to work, they need not be interfered with by surrounding signals. Without adequate EMI shielding, it would not be possible for modern cars to have the technology that they currently do and are consistently adding.

When not protected against, electromagnetic interference is responsible for disrupting the performance of systems, equipment, and electrical devices. This can affect a smartphone and its performance, but when critical applications fail (military, aerospace, medical), lives are in danger, and the risks are great. Designing and using RFI EMI shielding is often the best and most affordable way to deal with EMI.

Besides EMI generated from within a system or from other devices, EMI is created naturally, which means that am I is almost always present in some form or another. Protect your products and gear from the harms of EMI and RFI.
