Achieving the enhanced reliability of electronic system by application of EMI control measures

EMC is practiced in efficient operation, maintenance of reliability and safety of various electronic systems used in military and civil sectors and medicare. In the Indian context, it is essential to make indigenous products acceptable and competitive in domestic and international markets, especially in the European union, by designing reliable equipment. This paper addresses the following: (a) quality control for VLSI based systems through good EMC design practices, (b) sub-system module packaging, (c) hardening of electronic components for EMC and reliability, (d) protection of transient effects on digital circuits, (e) component-value-optimisation and (f) EMC maintenance considerations. The measurement results complying with the FCC specifications (class B) are included for a microprocessor subsystem.
