Research on Low Frequency Electrical Noise Defect Detection Technology for Electronic Components
On the basis of analyzing the characteristics and effects of low frequency noise,this article focuses on exploring detection techniques such as spectrum analysis,phase-locked amplification,and time-domain noise analysis.Through empirical research on 100 resistance strain gauges,the effectiveness of the combination of spectrum analysis and time-domain analysis in low frequency noise defect detection is verified.Experiments have shown that by comprehensively analyzing the characteristic parameters of noise power spectral density,mean,standard deviation,skewness,and kurtosis of the samples,abnormal noise samples can be accurately identified,providing a feasible approach for low-frequency noise defect detection.
