ElectroMagnetic Compatibility (EMC) applied to automotive modules

The electromagnetic compatibility has been evaluated in vehicle components and systems, both individually and in the vehicle as a whole, already assembled with its numerous electrical and electronic equipment. The reason for this growing concern is the ever-increasing use of on-board electronics in cars.

With the increasing speed of the processor in the modules and the demand for increasingly complex interfaces, it is necessary to develop more sophisticated control units, so the modules become ever more susceptible to electromagnetic fields. Therefore, the internal hardware of the control unit is designed to provide higher robustness of these components to comply in regards to EMC.

The objective of this paper is to support the basic concepts that should be considered in building a printed circuit board (PCB) module for automotive application, and the correct component design distribution and ground strategy to avoid EMC issues.
