Nowlan, M. J.

The edge-sealing technique is accomplished by a combination of a chemical bond between glass and aluminum, formed by electrostatic bonding, and a metallurgical bond between aluminum and aluminum, formed by ultrasonic welding. Such a glass-to-metal seal promises to provide a low-cost, long-lifetime, highly effective hermetic seal which can protect module components from severe environments. It is the purpose of this program to develop the above-described sealing techniques and to demonstrate their efectiveness by fabricating a small number of dummy modules, up to eight inches square in size, and testing them for hermeticity using helium-leak-testing methods. Non-destructive test methods will be investigated.
