PR-YOLOv8s: A Lightweight Improved YOLOv8s for Printed Circuit Board Micro-Defect Detection
Printed Circuit Boards (PCBs) are core components in electronics manufacturing. Six types of micro-defects, such as missing holes, mouse-bites and open circuits, may easily cause complete device failure. The original YOLOv8 employs only the P3/P4/P5 multi-scale detection heads, leading to severe loss of shallow fine-gr...
