Analysis of Heat Transfer and Fluid Flow in Manufacturing ofGlass-to-Metal Sealings in Electronic Components

在金属导体周围密封玻璃的程序涉及大量的经验主义和可接受的废品率。提出了一种制造方法，它可能会将过程加快一个数量级。将制定一项实验计划，以调查玻璃熔化和冷却周期的细节。二氧化碳激光器将提供均匀分布在玻璃柱周围的热量，一到两根金属导体通过该玻璃柱。在实验观察之后，将开发一个有限差分模型，该模型将作为工艺变量的函数来预测密封形状、内应力和系统的总体完整性。一个成功的计划将导致玻璃/电极密封件制造方法的显著改进，这反过来可以对电子行业这一方面的生产率产生积极影响。

Procedures for sealing glass around metal conductors involve a great deal of empiricism, and an accepted rate of rejection. A manufacturing method is proposed which potentially speeds up the process by an order of magnitude. An experimental program will be developed to investigate the details of the glass melting and cooling cycle. A CO2 laser will supply the heat uniformly distributed about a glass cylinder through which one or two metal conductors pass. A finite difference model will be developed following the experimental observations, with the proposed capability of predicting the seal shape, internal stresses, and general integrity of the system as a function of process variables. A successful program will lead to a significant improvement in the method of manufacturing glass/electrode seals, which in turn can positively affect the productivity of this aspect of the electronics industry.
