The purpose of this project was to determine the requirements for hermetic sealing terminals in military airborne electronic equipment and to compare these requirements with the capabilities of present terminals. Information from the Air Force, manufacturers, and users of hermetic terminals was analyzed to determine, requirements and tests suitable for terminals. The important electric characteristics are dielectric strength, corona voltage, current capacity, and insulation resistance. Tests related to environmental conditions include temperature aging, temperature cycling, temperature shock, vibration, mechanical shock, moisture resistance, ter¬minal strength, salt spray and gas leakage.
