ETP Probe (ETP Probe for CMI700 and CMI500 series)

Eddy probe(Widely called ETP Probe) is used for PCB through-hole Cu thickness measurement ,It's normally used on Hitachi cooper thickness tester CMI500 and CMI700 series. 

Brand: Oxford/Hitachi 

Suitable for PTH hole cooper thickness tester CMI500 and hole/surface Cu thickness terster CMI700

Technology data for ETP Probe:

PTH hole copper (Hitachi ETP Probe) test principle
Measured by the principle of eddy current, the ETP probe has a probe, the probe is composed of two coils,
when measuring, one of the coils emits electromagnetic field, the free electrons inside the conductor do circular motion in the electromagnetic field, generating a cyclotron current (eddy current), the eddy current generates an electromagnetic field in the direction opposite to the electromagnetic field generated by the coil, received by the other coil. An electrical signal is generated, and the thickness of the hole copper is measured due to the different thickness of the hole copper and the different size of the signal. It can be seen that the electrical conductivity of the metal is different, and the strength of the electrical signal is different, so the measured thickness is not the same.
