The strength of a vacuum tube subassembly is affected by many factors, including the subassembly design, the process used to bond the parts, and the type of equipment used to measure the strength. In this study, these variables were examined for a subassembly consisting of a molybdenum sleeve, a glass-ceramic insulator, and a molybdenum cylindrical frame. Results showed that compression testing of different designs ranged from 765 to 3170 pounds. No difference appeared in the strength of subassemblies due to variations in selected steps in processing. A self-aligning compression test fixture resulted in higher strength readings than those obtained with conventional fixturing.
