Thanks to the electromagnetic will affect the electronic products such as cell phone, laptop or digital camera fails to work; it is normally used to have the EMI shielding. Electromagnetic shielding (EMI shielding) provides “immunity” for electronic components that are susceptible to EMI and prevents the same components from transmitting excessive interference to their surrounding environment.
The main method for doing this now entails circuit grounding and design and placement of the critical components in the device architecture. EMI shielding compounds and Faraday cages are also used in a housing technique to further shield a device’s transmissions and protect against outside interference and disturbance to keep the electronics normally function.
