    摘要： A vacuum package assembly (20) is prepared by self-welding the flanges (32 and 43) of two housings (28 and 36) together under an applied pressure, while the housings (28 and 36) and any enclosed structure or device are contained within an evacuated enclosure. The flanges (32 and 43) are preferably made of copper, with their respective self-welding members (34 and 46) specially prepared to enhance self-welding performance. The preferred treatment for the self-welding members (34 and 46) is to deposit a thin layer of nickel onto the self-welding members (34 and 46 ), deposit a thin layer of gold over the nickel, and heat the bonding member to elevated temperature to interdiffuse the gold into the self-welding member (34 and 46 ).

    摘要： A dewar assembly is cleaned, baked out, assembled, and joined in a single vacuum system without exposing the components to ambient atmosphere. The vacuum system preferably has a first chamber with multiple subchambers that can be isolated from each other, and a second chamber that can be isolated from the first chamber. The multiple chambers and subchambers prevent cross contamination during the various process steps, and also permit multiple dewar assemblies to be batch processed at different stages simultaneously. The components of the dewar assembly are loaded into one subchamber and cleaned, and thereafter moved to another subchamber for bakeout. The dewar getter is heated in the second chamber and moved to one of the subchambers for assembly. The components of the dewar assembly are assembled and joined.
