The Computation of Radiated Emissions from Computer Chip and Packages

Abstract

Within the past 10 years, most countries have implemented standards which limit the strength of electromagnetic radiation allowable from computing devices sold in that country. These standards have been created mostly to control these devices’ potential to interfere with data communications systems, broadcast radio and television, and emergency systems. The result of these various regulations is that all manufacturers, not only computer manufacturers, must pay close attention to the Electromagnetic Interference (EMI) levels that their products produce. Pressures to shorten design cycle times, reduce product costs, higher performance systems and the need to meet EMI regulations has served to increase the interest in using modeling and simulation to help ensure optimum hardware designs. © 1998, The Japan Institute of Electronics Packaging.
