Statistical Appearance Modelling technology enables an AOI system to “learn real world variation” based on operator interaction with inspection task results. This provides an accurate statistical description of normal variation in a product. With modelling technology, the user does not have to anticipate potential defects as the system will “flag” anything outside the “normal production range”. And, since the system is programmed with real production variation, it is sensitive to small subtle changes enabling reliable defect detection. Autonomous prediction of process variation enables an AOI system to be set up from a single PCB with production-ready performance. Setup time can be

This paper will explore how test can be an integral part of manufacturing to assure High Reliability Products. We will discuss how test parameters and test techniques are effective in finding time zero vs. time dependent defects. Understanding of manufacturing processes in terms defect levels as well as defect types is very critical in defining test parameters, new test techniques and test alternatives. This ultimately can improve the yield, quality, and reliability. We will discuss the types of defects, time zero vs. time dependent defects, test parameters and effectiveness and new test techniques to find time dependent defects.

Zero-defect strategies and increased demands on the production of assemblies are making quality assurance in electronics production increasingly important. Continous miniaturization of components, ever higher packing densities and the associated hard-to-view assembly areas, as well as the increased use of components such as BGAs, QFNs and QFPs, pose a considerable challenge when it comes to high-precision quality control.
