Impedance test

Controlled Impedance (TDR) Measurement, Failure Detection and Impedance Calculation can be carried out by HYTEK. Manufacturing of PCBs require impedance test typically carried out on a test coupon from the production panel. These measurements can be done by standard impedance test, but measuring more precisely or measuring on a real PCB requires a Time Domain Reflectometer (TDR). The Differential Time Domain Reflectometer is able to perform controlled measurement directly on a real PCB and even on a fully assembled PCB.


Impedance/TDR Measurement can, for example, be used for examination and analysis of:

  • PCB
    • Controlled Impedance on a strip line (Test coupon)
    • Controlled Impedance directly on a real PCB including via holes
    • PCB failure detection and analysis
