SMT质量检测中的AOI技术及应用
资料介绍
随着电子制造业中印刷电路板元器件安装普遍采用表面贴片技术,产品的集成度更高,元器件体积更小,安装密度更大,传统的检测技术在技术和速度上都不能适应新的电子检测技术。而基于机器视觉的检测技术（AOI）可以快速、准确地实现对贴片安装产品缺陷的自动检测,是提高电子制造业自动化水平和产品质量的重要技术。对AOI的技术原理进行了阐述,通过分析AOI在工艺中放置位置和最终需要实现目标及其在SMT工序中的应用,充分表明AOI在SMT工艺中的优点。
With wide application of surface mounted technology（SMT） in printed circuit board assembly,the electronic products have higher integration,smaller components and higher assembly density,the conventional inspection can′t fulfill the assembly automation in speed and reliability.The automated optical inspection（AOI） based on machine vision can detect the defects of SMT rapidly and accurately.The principles of AOI technology are introduced.The advantages of AOI in the SMT are proposed through an analysis on the positions which AOI should be set during the process of technology,final goals,and an example used during the working procedure of SMT.With wide application of surface mounted technology（SMT） in printed circuit board as...
