Shielding material protects sensitive components from EMI and RFI


Electronic equipment manufacturers usually use electromagnetic interference (EMI) and radio frequency interference (RFI) shielding measures to protect sensitive digital circuits from external radiation, and also limit the potentially harmful radiation emitted by their products. But these manufacturers face the tough challenge of meeting EMI/RFI shielding requirements, such as material selection and converting selected materials into effective shielding components.


To meet these challenges, many OEMs turn to companies specializing in the conversion of flexible materials. In the early stages of the project, top companies can provide critical engineering support to improve product design and manufacturability.


The basic principle of shielding EMI/RFI shielding is a function required by many consumer electronic products such as televisions, radios, mobile phones and computers, as well as equipment used in the medical and aviation fields. The shielding function of these devices is achieved through the Faraday box. These Faraday boxes cover all electronic components and can effectively prevent electromagnetic radiation.
