Overview on design techniques for printed circuit board layout used in high technology products

Abstract

Computers used in current information technology equipment generate higher clock speeds than similar state-of-the-art products developed only a few years ago. Design techniques commonly used in the past have become insufficient for suppression of electromagnetic interference (EMI) at the printed-circuit level and, perhaps, for basic functional signal quality as well. An overview using a hands-on approach to solving radio frequency (RF) emissions on printed circuit boards is presented. Implementing the items presented will help reduce RF generated on the printed circuit board. Suppression of RF energy at the printed-circuit-board level minimizes costly containment schemes.<>
