Process Technology and Its Implications for Inspection and Manufacturing of Ceramic Multi-Chip Modules

该研究的主要目标是提高基于陶瓷的多芯片模块制造的质量、可重复性和速度。跨学科的努力将同时关注材料和加工问题，以及带铸陶瓷层的自动视觉检查。目前，缺乏对材料成分对悬浮液流变学和铸态性能（宏观和微观组织）影响的科学理解。这将通过一个实验程序来解决，该实验程序(1)将流变性能表征为悬浮成分和时间的函数，(2)确定层内的微观结构变化。从这个实验程序中获得的洞察力将用于导出缺陷发生的统计模型，这将随后驱动检查过程。将过程知识与计算机视觉和图像处理技术相结合的检验方法尚不存在。研究的最终结果将是改进尺寸控制和再现性，以及自动视觉检查带铸板。此外，这项工作将提供对材料系统，加工参数和微观结构发展之间关系的基本理解，这很容易适用于先进陶瓷部件的生产。这样的理解可以使生产更可靠的电子设备和组件成为可能。

9313126 Lewis The broad objective of the research is to improve the quality, reproducibility, and speed of ceramic-based multi-chip module manufacturing. An interdisciplinary effort will simultaneously focus on materials and processing issues, and on automated visual inspection of tape-cast ceramic layers. Currently, a scientific understanding of the effects of materials composition on both suspension rheology and as-cast properties (both macrostructural and microstructural) is lacking. This will be addressed by an experimental program which (1) characterizes the rheological properties as a function of suspension composition and time, and (2) determines the microstructural variations within the layers. Insights gained from this experimental program will be used to derive statistical models for defect occurrence, which will then drive the inspection process. An inspection methodology that combines process knowledge with computer vision and image processing techniques does not yet exist. The end result of the research will be improved dimensional control and reproducibilty and automated visual inspection of tape-cast sheets. In addition, this work will provide a basic understanding of the relationship between the materials system, processing parameters, and microstructural development that is readily applicable to the production of advanced ceramic components. Such understanding may allow the production of more reliable electronic devices and assemblies.
