Case Study Failure Analysis of an Ultra-High Vacuum Enclosure Made of a Silicon Chip and Borosilicate Glass for the Cold Atom Laboratory

In this paper, a failure analysis case study on a custom-built vacuum enclosure is presented. The enclosure’s unique construction and project requirement to preserve the maximum number of units for potential future use in space necessitated a fluorocarbon liquid bath for fault isolation and meticulous sample preparation to preserve the failure mechanism during failure analysis.
