PCB-MC is a new dataset for detecting missing components on printed circuit boards, featuring 197 distinct board types with footprint-level annotations derived from the RF100 dataset. The dataset includes multiple augmented samples per board type and introduces board type-aware cross‑validation splits to prevent layout leakage between training and test sets. Benchmark results show that supervised models suffer high false‑negative rates on unseen board designs, while unsupervised anomaly detection methods fail due to misalignment with board-specific references, highlighting the remaining challenges in missing component detection across diverse PCB layouts.

The paper introduces ISP-AD, the largest publicly available industrial anomaly detection dataset, featuring both synthetic and real defects from a factory floor. It focuses on challenging, small, weakly contrasted surface defects within highly variable structured patterns, addressing the bias of existing datasets toward ideal imaging conditions. Experiments demonstrate that even a small amount of weakly labeled real defects improves model generalization and that synthetic defects can serve as a useful cold‑start baseline for scalable training.

The paper introduces LUMIN, a lightweight network for manufacturing anomaly detection, and PSP, a four‑stage adaptive memory bank sampling pipeline that eliminates backbone forward passes. PSP achieves near‑random construction speed, 341× faster than FPS, while parallel similarity computation and stratified pixel sampling cut inference time by 20× with minimal accuracy loss. Experiments on five benchmarks show that LUMIN and PSP reach state‑of‑the‑art sampling accuracy with dramatically reduced latency and memory usage.
