Time Domain Reflectometry sends and measures the reflectance of electical pulses 

Each interface in a device partially reflects a pulse while a scan of the reflected signal is plotted versus time.  Comparing a known good device purposely damaged at known locations versus a bad device allows the localization of the damage in a bad device.

Global uses of TDR include prototype evaluation, customer returns, reliability rejects, production control, materials development, quality control, problem solving, failure analysis, and reverse engineering. The data produced by TDR includes TDR signal plots.

Strengths and Advantages of TDR:

    •    Fast (less than 10 minutes)
    •    Non-destructive
