Designing aluminum sealing glasses for manufacturability
- Sandia National Laboratories, Albuquerque, NM (United States); and others
Hermetically sealed aluminum electronic components have advantages over steel components from a manufacturing standpoint. They are lighter weight, cost less to machine, and can be sealed at lower temperatures. We have developed a family of new phosphate glasses, the ALSG series, that have the necessary thermal and chemical properties for producing reliable hermetic seals to aluminum alloys. The development of this glass family has included predictive techniques to minimize the time and effort required to integrate the technology into production environments. We will describe the developmental design matrix used to predict glass properties as a function of composition, thereby enabling the optimization of glasses for use in specific applications. We will also introduce a statistical model which is being investigated to optimize processing parameters of new glasses, decreasing the number of sealing runs required to achieve a quality hermetic component.
