This framework significantly enhances predictive maintenance and quality control for electronic devices, leading to improved safety and operational efficiency in critical applications.
Predictive Maintenance in Critical Power Electronics
Scenario: A leading manufacturer of industrial power inverters faced recurring failures due to undetected thermal stresses in their high-density Printed Circuit Boards (PCBs). Traditional monitoring methods were slow, labor-intensive, and lacked the precision to identify nascent hotspots, leading to costly unscheduled downtime and component replacements.
Solution: Implementing the Hybrid AI-Taguchi–ANOVA framework, the manufacturer integrated real-time infrared thermography with U-Net for precise thermal anomaly segmentation and an MLP classifier for identifying heat propagation patterns. The Taguchi-ANOVA methodology was crucial for optimizing the AI model's hyperparameters, ensuring high F1-scores and significantly reduced inference times (18% faster) tailored for embedded systems.
Impact: Within six months, the system accurately predicted thermal degradation in critical power components, enabling proactive maintenance. This resulted in a 25% reduction in unexpected equipment failures, a 10% decrease in overall maintenance costs, and an improved operational safety record. The interpretability of the AI models allowed engineers to understand the root causes of thermal anomalies, facilitating design improvements for future products.
