Electrical Resistance Measurements of Connector-Panel Interfaces

Abstract

This report indicates construction methods which would assure both vacuum and electrical-grounding integrity of the subminiature series A (SMA) vacuum bulkhead feedthrough connectors. This investigation was initiated in response to the finding that some of the connectors on the nonupsettable computer modules were not thoroughly grounded. This report presents the results of resistivity measurements on several selected conducting panel materials and several configurations of feedthroughs. The information reported is organized into procedures used to acquire the data, test results, and recommendations. Specific recommendations are made for the best materials and parts to achieve low resistance and a hermetic seal. Also, designs are recommended for the O-ring and groove design on bulkhead hermetic feedthroughs.
