The purpose of this study is discrimination of differences in metal plating condition. The sensor coil is placed away from the discrimination target by 0.5 mm, and the time derivative of the current flowing the coil is measured while the step voltage is applied to the coil. Maximum value of the time derivative of the current and the time at the maximum value are extracted from the measured current waveform, and used as inputs to SVM for discrimination. As a result, the plating and the plating peeling states can be discriminated. However, the number of metal foils, which corresponds to differences in peeling conditions, con not be discriminated 100 %.
