Abstract :
In designing a quality product such as a notebook computer using SMT chips, EMC design care must be taken in meeting the performance criteria. This paper addresses the EMI emission and immunity effects of a microprocessor based notebook computer system designed and developed in the laboratory. Careful design of the power supply, ground structure, and the clock distribution in a multilayer PCB and the use of a conductive coating or shielding of the plastic enclosure can improve the design performance, reducing the effect of EMI, crosstalk and noise resulting from unwanted signal pick-up
