EMI Protection
EMI Protection (also called EMI Shielding) is a way to prevent electronic devices from interfering with each other. Think of it like building an invisible shield around electronic parts. When electronics repair technicians talk about EMI Protection, they're referring to methods and materials used to stop electronic "noise" from one device affecting nearby devices. It's similar to how soundproofing works for noise, but for electronic signals. This is especially important in devices like phones, computers, and medical equipment to make sure they work properly without interference.
