Concealed corrosion testing in an aluminum multi-level interconnection
KAS 61-7 probe is a low-frequency probe in an absolute circuit. Its core system is shielded lateral interference from component edges or rivet currents. This probe has a (removable) aluminum element for increasing the sensitivity. This enables a direct adjustment to the conductivity values of the respective test device. The frequency range lies between 200 Hz and 100 kHz. At a sheet thickness of 1 mm, the signal image above shows 20% corrosion as well as „lift-off“ and „spacing“ in a direct comparison. The „lift-off“ signal moves to the left from the compensated zero point, the corrosion display remains fixed horizontally above it, and the „spacing“ signal moves to the right. This allows for a differentiation between corrosion and an air gap (spacing).
It was calibrated using test piece TP4.

Application:
Preferably corrosion testing, manual sorting tasks, crack detection on concealed cracks, without edge interference, independent of test direction. Corrosion testing on aluminum adhesive and rivet joints. Can also be optimized for other materials by exchanging the compensation plate (standard: aluminum).
