Web24 de fev. de 2024 · The impedance of a trace is calculated based on the placement of plane and signal layers in the PCB stackup. Make sure you understand the factors that influence transmission line impedance, and if needed, use a calculator to get an initial estimate of impedance before programming the required trace width as a design rule. Webthe signal trace exceeds this trace-length/speed criterion, then termination should be used. For example, PCB tracks for high-speed logic with rise/fall time of 5 ns should be terminated in their characteristic impedance if the track length is equal to or greater than 10 inches (where measured length includes meanders). things to do in hitchin herts
