Research in the EMC Design of SCM System

In the SCM (Single Chip Micro-control) system, EMC affects its working stability. All segments of the SCM system design are relation to the EMC design. According to the PCB board design of the SCM system, general it includes the components’ selection and layout, assigning wires, ground wires design, wave filtering and shielding design, etc. Researchers and experiments show that under some design requirements referred in this paper, the module design and data bus filtering design can improve the EMC capacity of the SCM system.
