Investigation of Conducted Immunity and Spatial Distribution of RF Currents for a 2-Sided PCB

Influence of the RF noise in automotive 12-volts power distribution network and its impact on electronic control unit is investigated. A magnetic near-field scanner is used to inspect the penetration of the injected RF currents on an automotive module. Spectral and spatial scans are useful in investigation of the power distribution robustness. It is anticipated that spatial view of conducted RF currents in a printed circuit board can result into design practices that enhances the EMI robustness of a product and its functional quality.
