How to Test PCB Traces with a TDR – BitWise Laboratories

 

Testing PCB traces accurately is critical for ensuring signal integrity, especially in high-speed circuit designs. One of the most reliable methods for this is using a Time Domain Reflectometer (TDR). If you’re wondering how to test PCB traces with a TDR, BitWise Laboratories provides advanced solutions and guidance to help engineers and manufacturers achieve precise testing results.

A TDR works by sending a fast electrical pulse down a trace and measuring the reflections caused by any impedance changes. These reflections can indicate issues like open circuits, shorts, or impedance mismatches along the trace. By analyzing the reflected waveform, engineers can identify the exact location and nature of the fault, ensuring that design and manufacturing defects are corrected early.

Our testing systems and expertise help clients measure trace length, impedance consistency, and discontinuities with exceptional accuracy. Knowing how to test PCB traces with a TDR not only improves performance but also reduces costly redesigns. We recommend performing TDR testing during both the prototype and production stages to maintain high-quality standards.

In today’s high-frequency electronics, even minor impedance variations can impact signal quality. That’s why BitWise Laboratories emphasizes precision TDR analysis to ensure every PCB meets design expectations. With expert tools, detailed data visualization, and professional support, engineers can rely on us for dependable testing and validation of their electronic designs.
