ABSTRACT:
Systems and methods for providing a sealed container having a reduced pressure atmosphere are disclosed. The container is suitable for housing an infrared detector array. Outgassing can be enhanced by adding features to solder preforms that maintain pathways for gasses to more readily exit the container prior to sealing thereof. Getters can be used to mitigate undesirable gases within the sealed container. One or more bolometers can be used to determine if the sealed container is leaking. A vacuum positioning fixture can be used to assemble the components of the infrared detector assembly and to place the infrared detector assemblies into a vacuum chamber. The cost of manufacturing such infrared detector assemblies may be reduced and the reliability thereof enhanced.
