Název v původním jazyce

Thick Film Resistors Testing by Electro-Ultrasonic Spectroscopy

Popis výsledku v původním jazyce

The paper presents new principle of non-destructive testing of thick film resistors. Tested sample is excited by harmonic AC electrical signal with frequency fE and by the ultrasonic wave with frequency fU. On the interface between two conducting particles the intermodulation signal with frequency fm given by superposition or subtraction of exciting frequencies fE and fU is created. The main advantage of this method is the detection of electrical signal on the frequency different from frequencies of excitation signals. We have studied the properties of polymer based thick film layers and cermet thick film resistors. Polymer based samples were made using different resistive pastes and dipping silvers. The mixture of carbon and graphite conducting particles and silver flakes suspended in different polymer vehicles were used for the resistive pastes and dipping silvers (DiAg), respectively. Amplitude of intermodulation signal Am, noise and non-linearity depend on the properties of point c
