Data rate need to be transmitted in PCB trace is increasing day by day. Because of that terms like skew, jitter is becoming critical and its margins are getting narrow. Also, tolerances of copper and dielectric in PCB fabrication is getting strictly precise. In the scenario, relevance of the non-linearity of dielectric is getting important, Fiber Weave Effect (FWE) which can cause a devastating effect on signal integrity (SI) in high-speed circuit boards. This paper is discussing the analysis of FWE on design consideration of the modern high-speed digital board.

Keywords : Skew, Jitter, Fiber Weave Effect, Signal Integrity.
