How to test PCB traces with a TDR at BitWise Laboratories

 

At BitWise Laboratories, we specialize in advanced techniques for evaluating printed circuit boards. One of the most accurate methods is Time Domain Reflectometry (TDR). If you are wondering how to test PCB traces with a TDR, the process is straightforward yet powerful. A TDR sends a fast electrical pulse down the trace and measures reflections caused by changes in impedance. These reflections reveal issues such as breaks, shorts, or variations in trace geometry. By analyzing the reflected waveform, engineers can pinpoint the exact location of defects, ensuring reliable signal integrity. This method is essential for high-speed digital designs where precise impedance control is critical. At BitWise Laboratories, we use TDR testing to guarantee that every PCB meets strict quality and performance standards.
