Abstract
Ensuring the quality of PCB products is vital, with various inspection methods and technologies being proposed. Conventional methods for visually examining PCBs present various constraints and are frequently unable to guarantee flawless outcomes. Machine vision technologies for automatic inspection of PCB surfaces are now powerful and effective tools for addressing quality control issues in the industrial field. Hence, this research focuses on identifying surface flaws in PCB images using a lightweight YOLOv8 model (YOLOv8n-tiny). In summary this study mainly focuses on enhancing real-time object detection model performance capable of accurately identifying and locating fault within PCBs under real time situation using a dataset containing six categories of PCB defects. Furthermore, we carried out a comparison study between our proposed model and other models mentioned in the related work section. Our detector outperformed the existing models by achieving a mAP@50 of 99.08%.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
