A Lightweight PCB Defect Detection Method Based on Heterogeneous Feature Enhancement and Discrepancy-Guided Fusion
Accurate detection of small and weak defects is essential for ensuring the manufacturing quality and operational reliability of printed circuit boards (PCBs). Existing detectors, however, remain constrained by insufficient fine-grained feature representation, interference from repetitive conductive backgrounds, localiz...
