Hermetic packaging for microwave modules. Final report

PDF Version Also Available for Download.

Description

Microwave assemblies, such as radar modules, require hermetically sealed packaging. Since most of these assemblies are used for airborne applications, the packages must be lightweight. The aluminum alloy A-40 provides the needed characteristics of these applications. This project developed packaging techniques using the A-40 alloy as a housing material and laser welding processes to install connectors, purge tube, and covers on the housings. The completed package successfully passed the hermetic leak requirements and environmental testing. Optimum laser welding parameters were established in addition to all of the related tooling for assembly.
