Application of Electro-Ultrasonic Spectroscopy for NDT of Electronic Components
Original language description
The paper presents new principle of non-destructive testing of electronic thick film resistors. This method is based on ultrasonic phonons interaction with electrons in the nonlinear region caused by defect ("defect caused nonlinearity"). Tested sample is excited by harmonic AC electrical signal with frequency fE and ultrasonic vibration with frequency fU. New harmonic signal with frequency fi is created on the defect caused nonlinearity. The frequency fi is given by the superposition or subtraction ofexciting frequencies fE and fU. The advantage of this method consists in detection of electrical signal with frequency different from frequencies of excitation signals.
