Conditional Anomaly Detection for Quality and Productivity Improvement of Electronics Manufacturing Systems

Part of the Lecture Notes in Computer Science book series (LNISA,volume 11943)


Today the integration of Artificial Intelligence (AI) solutions is part of the strategy in the industrial environment. We focus on anomaly detection in the framework of manufacturing electronic cards manufacturing under mass production conditions (24/7). Early anomaly detection is critical to avoid defects. Researches and applications of anomaly detection techniques in the industry have been published but when they face production constraints success is not guaranteed. Today’s manufacturing systems are complex and involve different behaviors. We propose and evaluate a new realistic methodology for detecting conditional anomalies that could be successfully implemented in production. The proposed solution is based on Variational Autoencoders (VAEs) which provide interesting scores under the near real-time constraints of the production environment. The results have been thoroughly evaluated and validated with the support of expert process engineers.
