      Analysis of discharge parameters affected by electrode motion speed based on deep learning and traditional machine learning

      • 摘要: 静电放电(electrostatic discharge,ESD)是影响电子设备安全运行的关键因素,其波形特性受多种参数如接近速度的显著影响。因此,本研究利用自主研发的电极移动速度效应测试仪采集ESD波形数据,并利用等宽分箱及多种归一化方法对原始数据进行预处理,提取时域、频域和形态学特征。基于此,本研究构建了多种回归预测模型,包括传统机器学习方法以及深度学习方法用于ESD参数的多参数预测。实验结果表明,在基于Min-Max归一化的数据集上,SVM模型在ESD参数预测中表现最佳,决定系数分别达到了0.991 3和0.982 9,均方误差和平均绝对误差均显著低于其他方法。这表明,SVM在处理小样本和高维数据时具有较高的鲁棒性和泛化能力。本研究系统地比较了多种传统与深度学习模型,为ESD参数预测提供了全新的思路,并为静电防护技术的优化与应用提供了理论依据和实践指导。

         

        Abstract: Electrostatic discharge (ESD) is a critical factor affecting the safe operation of electronic devices, and its waveform characteristics are significantly influenced by various parameters, such as the approach speed. To this end, this study utilizes a self-developed electrode movement speed effect tester to collect ESD waveform data and preprocesses the raw data using equal-width binning and various normalization methods. Time-domain, frequency-domain, and morphological features are then extracted. Based on this, multiple regression prediction models are constructed, including traditional machine learning methods, such as Support Vector Machine (SVM), Random Forest, Decision Tree, and K-Nearest Neighbors, and deep learning methods, such as long short-term memory neural network Short-Term Memory Neural Network (LSTM), one-dimensional Convolutional Neural Network, Transformer, and Transformer + LSTM), for multi-parameter prediction of ESD parameters such as peak value and rise rate. Experimental results indicate that, on the dataset normalized using Min-Max, the SVM model performs the best in ESD parameter prediction, with R² values of 0.991 3 and 0.982 9, and significantly lower mean squared error (MSE) and mean absolute error (MAE) compared to other methods. This demonstrates that SVM exhibits higher robustness and generalization ability when handling small sample sizes and high-dimensional data. This study systematically compares various traditional and deep learning models, providing a novel approach to ESD parameter prediction and offering theoretical foundation and practical guidance for the optimization and application of electrostatic protection technology.
