Why Are There Serpentine Traces on FPC Circuit Boards?
Introduction
Serpentine traces are a common feature on PCBs, including FPCs, where they play a critical role in signal integrity, particularly in high-frequency circuits. These traces help compensate for time delays in high-speed signals, ensuring synchronized signal transmission across related signal lines.
Understanding the purpose and design considerations of serpentine traces is crucial for optimizing the performance of high-speed circuits.
