Abstract

The invention discloses a ceramic embedded refrigeration type infrared focal plane detector connecting piece, which relates to the technical field of ceramic packaging shells. It includes metal components, ceramic parts and metal leads. The metal component is composed of an upper Kovar ring and a lower Kovar ring. The lower end of the upper Kovar ring is welded to the upper end of the lower Kovar ring. The ceramic parts are embedded in the On the lower Kovar ring, the metal lead wire is welded and connected to one end surface of the ceramic part. The invention uses metal as the main material, and the method of embedding alumina ceramics for packaging has the advantages of small volume of ceramic parts, high mechanical reliability, small welding area, and low air leakage probability.

Description

technical field [0001] The invention relates to the technical field of ceramic packaging shells, in particular to a ceramic embedded refrigeration type infrared focal plane detector connector. Background technique [0002] Infrared focal plane detector (Focal Plane Arrays, FPA) components are the core components of high-performance infrared systems, which play an important role in the fields of aerospace, industry, environment and medicine, and have great influence on the reliability and life cycle of infrared detectors. Cost matters. [0003] With the continuous development of high-performance infrared systems, it puts forward strict requirements for infrared focal plane detector components, such as light weight, small size, easy to use and carry, high performance, and high reliability. The existing ceramic annular refrigeration type infrared focal plane detector connectors can no longer meet the requirements of the new generation infrared system for detector connectors. ...
