  • Mechanical retention system for braze and solder joints
    Patent number: 6405918
    Abstract: Brazing or soldering of pieces of low wettable materials (1, 3), such as single crystal silicon, is accomplished by sandwiching the brazing material (5) between the pieces and sealing the edges of the brazing material with a tape (11) wrapped about the periphery of the brazing material, mechanically placing that tape in compression and maintaining that compression while heating (21) the sandwiched assembly to the brazing temperature of the brazing material. The tape possesses the characteristic of being non-wettable by the brazing material in the molten state and, hence, is impermeable to that melt. The tape may comprise a fibrous porous ceramic material.
