Researchers have developed a novel two-phase framework for detecting defects on printed circuit boards (PCBs). The first phase utilizes structure-guided masked pretraining on unlabeled PCB images to help the model learn structural priors. In the second phase, this pretrained model is fine-tuned for defect detection, incorporating a spatial continuity regularization term to improve localization of defects. This approach achieved strong performance on the DsPCBSD+ dataset, outperforming existing methods. AI
