Abstract

Abstract

Crosstalk between conductor traces on printed circuit board is one primary source of EMI in switching power supply.Field analysis is carried out to study the electric field on PCB.Simulation and measured emission map offer valuable visual aids to PCB designer,coupling index is introduced to indicate coupling level between two traces.Based on these emission maps and coupling index PCB designer can arrange critical trace in suitable location,so crosstalk problem between traces can be suppressed during PCB design stage.
