A method for batch brazing in a diffusion furnace includes inserting a plurality of fusible parts into a plurality of slots of at least one quartz boat, transporting the at least one quartz boat, including the fusible parts, into an interior of a reaction chamber of the diffusion furnace, sealing the interior of the reaction chamber, adjusting an atmosphere of the interior of the reaction chamber according to a recipe, moving a preheated furnace heating element from a location spaced apart from the reaction chamber to a location in substantial proximity with the reaction chamber to increase a temperature of the atmosphere of the interior of the reaction chamber above a predefined brazing temperature for a predefined brazing time period according to the recipe.

Jet stack brazing in a diffusion furnace

A method for batch brazing jet stacks in a diffusion furnace. The method may include inserting fusible parts into slots of quartz boats and transporting the quartz boats into an interior of a reaction chamber of a diffusion furnace. An operator may seal the interior of the reaction chamber and an atmosphere of the interior of the reaction chamber may be adjusted according to a brazing recipe. A preheated furnace heating element may be moved toward the reaction chamber to increase a temperature and the fusible parts may be brazed according to the brazing recipe. The furnace heating element may then be moved away from the reaction chamber, the chamber unsealed, and the brazed parts removed.
