Emission Reduction Techniques for Printed Circuit Board

Abstract

In this paper two prototypes of PCB have been used to measure the emission pattern from the board. Both boards have the same dimensions, material properties and connectors. In prototype PCB1(Good Board) have been created to improve the emission results and analyze the difference in results by following proper layout rules and incorporating various emission reduction techniques. However PCB2(Bad Board) proper layout techniques are not followed to analyze the radiation pattern and it has been created to violate the layout rules. The emissions from the two boards were then measured and compared demonstra -ting an improvement in radiated emissions and passing FCC Class B limits.
