The development of wireless technology has increased the risk of signal interference. Any electronic device can catch unwanted signals that can interrupt the working of circuits. That’s why companies do Electromagnetic Compatibility (EMC) shielding to avoid these problems. In this article, we will shed light on EMC shielding and cover up the basic concepts you should know about.
EMC Shielding – A Brief Overview
Electromagnetic Compatibility (EMC) shielding is an approach taken to ensure the protection of the sensor signals from external electromagnetic signals. It also prevents the signals to leak out and interfere with other electronic devices. If an electronic component does not have shielding, it can cause several issues, such as interrupted communication or a completely down system. EMC shielding covers many domains including military, health, and other emergency services.
Nowadays, EMC has become an important part of electronic items. Industrialists also introduced different standards to explain whether the item is up to the mark. They perform EMC testing to know where the component is standing right now. It reduces the effect of the fields, as electromagnetic signals can otherwise hurt circuit operations. EMC shielding has two major elements, as follow:
- Emission: Emission describes the unwanted production of strong electromagnetic signals. It must be less than the limits otherwise it can disturb the equipment.
- Susceptibility and Immunity: Susceptibility and immunity refer that how equipment is going to react against the emissions.
