AOI for Process Improvement
December 31, 1969 |Estimated reading time: Less than a minute
Expanding the role of AOI from defect detection to line-quality improvement tool, the ADVISOR process control software and AOI system solution provides an easily accessed data bank for all relevant SMT quality data, such as AOI resource information, process machine parameters, and set-up data.
The system automatically links post-reflow inspection data with paste inspection data and paste-inspection results with printer system events. An alarm engine alerts operators to out-of-parameter processes and can be used to stop a machine. The AOI system and ADVISOR software can be integrated with an existing manufacturing execution system (MES) or shop-floor system to monitor all PCB data. Real-time access to data is said to help manufacturers detect trends that are causing defective boards, correct parameters of processing equipment before defects occur, and reduce a line's defects per million opportunities (DPMO).
