End-to-end deep learning framework for printed circuit board manufacturing defect classification
Problem
Quickly and accurately detecting and classifying the types of manufacturing defects present on printed circuit boards.
Why it matters
Automated, accurate PCB defect detection supports manufacturing quality control at scale.
What the AI did
A complete deep-learning framework using a single-step object detection model detects and classifies PCB defects, benchmarked against FRCNN-ResNet50, RetinaNet and YOLO on the same PCB defect dataset.
Results
98.1% mAP (IoU=0.5) on low-resolution test images; 3.2% above low-resolution SOTA (YOLOv5m) and 1.4% above high-resolution SOTA (FRCNN-ResNet FPN); ~3x fewer parameters (7.02M).
Impact
Outperformed state-of-the-art baselines on the same dataset with roughly 3x fewer parameters.
