Comprehensive Guide to TDR Testing for PCB Traces: Bitwise Laboratories

TDR Testing for PCB Traces (Time Domain Reflectometry) is an essential diagnostic technique used to analyze impedance characteristics and identify discontinuities in signal traces on printed circuit boards (PCBs). This testing method is crucial for maintaining signal integrity in high-speed digital circuits, where even minor impedance mismatches can cause signal reflections, data corruption, and degraded performance. Bitwise Laboratories specializes in advanced TDR testing, providing precise impedance profiles and detailed analysis to ensure reliable and high-performance PCB designs. What is TDR Testing for PCB Traces? TDR Testing for PCB Traces involves sending a fast-rising electrical pulse through a signal trace and observing the reflected signal to measure impedance variations. When the pulse encounters an impedance discontinuity, such as a trace width change, via, a connector, or defect, part of the signal is reflected. By analyzing the reflected waveform, engineers can iden...
