Why Use Serpentine Routing in PCBs?Chengchi Expert Engineer Breaks Down 3 Key Purposes

As a newcomer to PCB design, you've likely been puzzled by this: why do experienced engineers insist on routing some traces in a serpentine pattern, twisting and turning, when a straight line would be shorter and faster? Sometimes, serpentine routing even occupies more board space and increases desi
