Introduction to Trace Length and Time Delay in PCBs In high speed printed circuit board (PCB) design, the physical length of traces between components has a significant impact on signal integrity. As signal speeds increase, the time it takes for a signal to propagate down a trace becomes a critical […]

What is PCB Impedance? PCB impedance refers to the opposition to the flow of alternating current (AC) in a printed circuit board (PCB). It is a critical factor in ensuring the integrity of high-speed digital signals and maintaining signal quality. Impedance is measured in ohms (Ω) and is determined by […]

Understanding PCB Impedance What is PCB Impedance? PCB impedance refers to the opposition to the flow of alternating current (AC) in a PCB trace. It is a complex quantity that combines resistance, capacitance, and inductance. Maintaining proper impedance control is essential to prevent signal reflections, reduce crosstalk, and ensure optimal […]

What is a PCB? A Printed Circuit Board (PCB) is a thin board made of fiberglass or other composite material, with conductive pathways etched or printed onto the surface. PCBs are used to mechanically support and electrically connect electronic components using conductive traces, pads, and other features. They are the […]
