Global Report Released on the EMI and RFI Shielding Materials and Technologies Markets

Global Industry Analysts (GIA) Inc. has released a comprehensive report on the global EMI and RF shielding materials and technologies markets. The report states the forecast of this market will reach $7.9 billion by 2020.

The Basic Principles of Shielding

1403 F4 coverToday’s electrical and electronic devices are subject to mandatory EMC requirements throughout the world. Many devices operate at high frequencies and are very small. They are placed in nonconductive plastic cases providing no shielding. Essentially, all these devices cannot meet these mandatory requirements or they may cause interference to other devices or receive interference causing susceptibility problems without a proper program of EMI control. This program consists of identifying the “suspect” components and circuits that may cause or be susceptible to EMI. This is completed early on in the program to allow for an efficient design in keeping the cost of dealing with EMI as low as possible. A complete EMC program consists of proper filtering, grounding and shielding. This article will discuss the latter, but the other factors cannot and will not be ignored or given insufficient priority.
