Brief Introduction
The PCB manufacturing industry is facing challenges in maintaining high-quality standards, particularly in the detection of solder joint defects post-wave and reflow soldering. Existing solutions often rely on manual inspection or less efficient automated systems that are prone to errors. This dataset aims to address the specific technical challenge of accurately identifying and classifying defects in solder joints, fulfilling the business requirement of enhancing inspection efficiency and reliability. The dataset consists of images collected using high-resolution cameras in controlled lighting environments, ensuring clear visibility of defects. Quality control measures include multi-round annotations, consistency checks among annotators, and expert reviews to ensure high accuracy. The data is organized in JPG format, with each image labeled according to its defect type and location.
