Electromagnetic Compatibility Requirements of Printed Circuit Boards Design
The design and layout of a printed circuit board is crucial to the functionality and electromagnetic compatibility (EMC) performance of the product. The proper layout in printed circuit boards must satisfy EMC requirements in board level and system level. Some of these requirements is about placement of components, board partitioning, trace routing and return path continuity. Designers must have strict control on these mentioned requirements. In this paper we study these cases and present their relevant design notes. Also we provide design points about electromagnetic compatibility requirements of the power and supply system, shielding, digital and analog circuits on printed circuit boards. They are all must be considered to meet emission and susceptibility requirements of the PCB.
