NDT of thick film resistors by noise spectroscopy
Original language description
The noise spectroscopy measurements of thick-film resistors are proposed as a non-destructive testing method for the quality and reliability prediction and possible types of failure evaluation. The thick-film layer structure consists of metallic grains and inter-grain glass layers. Junctions between the metallic grains and glass layers are sources of noise and non-linearity. Important sources of noise are in the vicinity of defects and in the contact region. The main advantages of a noise testing are hiigher sensitivity than DC measurements during life tests. The kinds of noise spectra in view of reliability diagnostic are mainly the typical poor-device indicators like burst noise, generation-recombination noise, 1/f noise, and the 1/fa noise. The non-linearity of the thick-film layer structure is proportional to the distortion of the pure harmonic signal applied to the sample, and is connected with physical anomalies. The noise spectroscopy and non-linearity NDT can be used to adjust
