Research Overview on Reliability of Infrared Focal Plane Array Detector Assemblies

摘要

Infrared Detector Dewar Cooler Assembly(IDDCA) is the key component of infrared system, and the reliability of IDDCA determines the reliability of the system and affects the application of the system to a great extent. Reliability research is of great significance for the engineering application of IDDCA. In this paper, research progress of reliability model, failure modes, acceleration factors, and reliability tests on the assemblies are introduced. Optimizing process and life cycle cost during the manufacturing, and evaluating reliability relying on database are described. In addition, the main thought of reliability research on the assemblies is briefly analyzed . This provides a reference for the domestic reliability research of the assemblies.
