Printed Circuit Interconnect Design To Mitigate EMI In Circuit Boards

This paper presents Printed Circuit Interconnect Design to Mitigate EMI in Circuit Boards. Due to miniaturization, advances in component packaging and the requirement of low volume and less weight in military systems, the design of interconnects on Printed Circuit Boards have become critical. The PCB conductor track is no more used as a simple conductor to provide point-to-point interconnection. It is a component by itself, similar to the distributed elements used in RF circuit design. Due to ever increasing requirements of clock speeds, reducing slew rates of clock pulses on the electrical side and ever reducing track widths and via diameter on the mechanical side, more importance is to be given to the layout design of the PCB.
