The metal lead wire in dewar is between the ROIC and the ceramic lead circle,and it can provide digital signal and analog signal for the ROIC,and export the output signal of the ROIC. The dewar structure of IR detector assembly is introduced,and the physical characteristics of the metal lead wire are analyzed at 77K. The maximum current that can flow through the metal lead wire is calculated theoretically,and is verified by experiment.
