With constant development of information technology, electronic products are becoming increasingly complicated in terms of their functions, categories and structures, driving PCB design towards direction of multiple layers and high density. As a result, much attention has to be paid on EMC (Electromagnetic Compatibility) of PCB design since EMC design of PCB not only ensures normal and stable working of all the circuits on board so that they won't be mutually interfered with each other but also effectively decreases radiation transmission and conducted emission of PCB in order to stop circuits from being interfered by external radiation and conduction. Interference is the foremost enemy of EMC. But, engineers, you should stop worrying from this article on.
