Is your equipment EMI/RFI protected?

February 2, 2016

The world today is increasingly electronic, with millions of waves and signals floating through the air at any given moment. The electromagnetic waves generated by electronic devices can easily negatively affect other, similar, electronic devices. Such affects are called Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI). EMI and RFI may cause malfunctions, specifically, the suppression of signals generated internally in a device, external ambient interference with equipment operation, or emissions generated internally that will interfere with equipment operation. Therefore, EMI and RFI are potential problems in any industry.

In order to prevent EMI or RFI, shielding agents may be used as protection. In most cases, EMI/RFI Shielding is in the form of a liquid or spray. The spray is often acrylic based, and is applied to plastic electronics housings. Highly pure metals such as nickel, silver, and copper in the spray help to reduce or completely eliminate EMI and RFI interference. EMI/RFI Shielding agents are also available as paints and brush on coatings.
