The electronic products being developed now must pass stringent certifications before it hits out into the market. With the full-fledged launch of wireless and other newer technologies, the EMC (Electro Magnetic Compatibility) problems become alarmingly high. In order to meet the stringent compliance requirements posed by FCC, IEC, CE, UL the design must be really robust.

The objective of this paper is to make the user understand the basics of EMC and to apply these
concepts while designing a successful printed circuit layout board. In this paper we will be going through the different standards of IEC (International Electrotechnical Commission) and their interpretation.
