Understanding how EMI Shielding Works
EMI and RFI are all around us Because of primarily humans and some nature. Problems with protecting against these types of interference have long been a problem for engineers. However, the problem only worsens as more EMI enters our world. Typically, individuals do not notice problems with EMI in their modern electronics even though so much of what they use contains at least some small chip or motherboard. A personal car alone can have upwards of 50 electronic devices, such as HVAC controls, GPS, and satellite radio. EMI and RFI shielding are tools that are widely used to allow our modern technological world to thrive and continue expanding.
How does am I shielding work?
Electromagnetic interference occurs when one signal picks up an interfering signal from another device. EMI shielding is designed to protect devices from picking up harmful signals while also preventing the device from pushing EMI into the world. Protecting EMI from escaping is as important as protecting it from entering the device. Often, engineers use many electronic devices to build one extensive system. As mentioned above, a car is a prime example of this. With all these small electronic devices within a confined space, they need to avoid crossing signals and interfering with one another. Modern vehicles would not be as technologically advanced without EMI shielding, which prevents electromagnetic interference from spreading throughout the car and beyond.
Smartphones are another excellent example of why EMI shielding is needed. Although the devices are relatively small, they have many sensitive and intricate electronics working together. EMI shields are used to block and prevent random signals from frying and damaging sensitive electronics.
