Abstract:

A novel low temperature vacuum seal and method of making same for joining a nonmetallic element, such as an optical port, to a metallic element is described which comprises first and second thin metallic layers applied to the nonmetallic element to provide substantial adhesion and solderability to the nonmetallic element, and a third metallic layer applied to the metallic element to provide solderability to the metallic element, the nonmetallic and metallic elements being joined by a layer of low temperature solder interfacing their respective solder surfaces. A further thin metallic layer may be applied to the nonmetallic element to provide substantial wetability to the solderable second layer.
