AOI技术在激光微孔产品检查中的应用

在过去几年里,小型PCB诸如硅芯片级以及便携式移动电话的生产者和设计者们已经发现:如果要保持自己的竞争力并具备生产高密度封装板能力,就必须采用微孔技术。微孔技术的出现要求针对微孔缺陷的有效检测手段对工艺进行过程控制。本文对激光微孔的自动光学检测进行了详细介绍。

AOI in Laser Drilled Microvia Production

Over the past few years, manufacturers and designers of small-form PCBs such as silicon platforms andcellular phones have increasingly found that microvia technology must be used if they are to remain competitive andcapable of interconnecting high density packages. Microvia technology required an process control guardian to detectdefects of microvia effectively.In this paper, automated optical inspection of laser microvia was detailedly introduced.
