Noise, Non-Linearity and Electro-Ultrasonic Spectroscopy for Testing of Resistors

Original language description

The quality and reliability of polymer based and cermet thick film layers were tested both by standard testing methods based on the measurements of the low frequency noise spectra, non-linearity and new proposed method: Electro-Ultrasonic Spectroscopy. The samples were made using different resistive and conducting pastes, both laboratory and commercially produced. The results of standard measuring methods are compared with those of the electro-ultrasonic spectroscopy. This method is based on the phononinteraction with conducting electrons and on the change of the contact area among the conducting particles. The ultrasonic signal changes the contact area between the conducting grains in the resistor structure and then the resistance is modulated by thefrequency of ultrasonic excitation. Resultant intermodulation voltage appearing on the sample depends on the value of AC current varying with frequency fE and on the ultrasonic excited resistance change ?R varying with frequency fU.
