What Devices Need EMI RFI Shielding?

Do all electronic devices need EMI shielding? Electronic technology is developing rapidly, and there does not seem to be much slowing this down. As a result of this growing landscape, designers and engineers must struggle with the growing issues of EMI and RFI. It is important to deal with this problem because EMI creates signals and waves that cause electronic devices to malfunction.

Electronic Devices Need EMI RFI Shielding

Considering the number of electronics in any given space, EMI (electromagnetic interference) and RFI (radio frequency interference) pose a serious threat to all electronic devices, including medical, military, and commercial devices. When electronics are not properly protected, the equipment can malfunction and fail. The cost-effective solution for most electronics is an EMI-RFI shielded enclosure.

EMI Shielding

RFI shielding is designed to protect against emitted signals and must meet specific EMI-RFI standards. Because it is impossible to eliminate EMI and RFI globally, engineers must use shielding enclosures as effective solutions.  EMI RFI shielding is often applied to electronic enclosures internally as a spray. The spray is applied to plastic enclosures that reduce interference problems. Shielding can also be brushed onto the exterior of an enclosure. When applied externally to a device, shielding material often consists of copper, silver, and nickel to reflect electromagnetic radiation.

If you work in the electronics industry, you must worry about these issues. Some industries even have a minimum standard set to ensure that devices work as they should. For instance, the medical industry relies on shielding as a means of preserving life. When EMI and RFI issues occur, a person could lose their life. Regardless of the function or purpose of your devices, you should strongly consider how EMI RFI shielding can benefit your design.
