The Need To Control Routing Impedance
The design approach of controlled impedance routing is a key ingredient of high speed PCB design, in which effective methods and tools must be adopted to ensure the intended high speed performance for your PCBs. So unless you carefully design your routes within your PCB, the impedance would be uncontrolled, and its value would vary from point to point throughout the trace. And because your PCB traces don’t act like simple connections at high...
