Abstract

The invention discloses a ceramic embedded cooled infrared focal plane array detector connector, and relates to the technical field of ceramic packaged shells. The connector comprises a metal component, a ceramic piece, and a metal lead. The metal component is composed of an upper Kovar ring and a lower Kovar ring, and the lower end of the upper Kovar ring and the upper end of the lower Kovar ring are connected by welding. The ceramic piece is embedded into the lower Kovar ring. The metal lead is welded to one end face of the ceramic piece. The connector is packaged in a method in which metal is used as the main material and alumina ceramic is embedded, and has the advantages of small size of the ceramic piece, high mechanical reliability, small welding area, and low 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. ...
