How to Test PCB Traces with a TDR – BitWise Laboratories

 

Testing PCB traces with a Time Domain Reflectometer (TDR) is one of the most accurate methods to detect signal integrity issues, impedance mismatches, or broken traces. At BitWise Laboratories, we use advanced TDR technology to send fast electrical pulses through a circuit board. By analyzing the reflected signals, engineers can pinpoint faults, measure trace lengths, and verify impedance consistency. This method helps ensure high-speed circuits meet design specifications and perform reliably under real conditions. Knowing how to test PCB traces with a TDR allows manufacturers to identify hidden defects early, reduce costly rework, and maintain quality control throughout production. It’s a key step for modern electronics testing and PCB validation.
