RefDiffNet: Learning to Expose Subtle PCB Defects Before Detection arXiv:2606.00852v1 Announce Type: new Abstract: Printed circuit board (PCB) defect detection is challenging because many defects are small and difficult to distinguish from complex background patterns. Most deep learning-based PCB inspection methods rely only on the inspected PCB image for defect detection, ignoring the defect-free reference image that encodes the expected layout of traces, pads, and other PCB structures.
