Systems and methods to control fabrication of an assembly involve a first end sheet having an interior surface and an exterior surface, opposite the interior surface. A system includes interior sheets, the interior sheets including a first interior sheet at one end of a stack of the interior sheets and including a last interior sheet at an opposite end of the stack of the two or more interior sheets, the first interior sheet being adjacent to the interior surface of the first end sheet, and a second end sheet having an interior surface and an exterior surface, opposite the interior surface. The last interior sheet is adjacent to the interior surface of the last end sheet, and the interior surface of the first end sheet or the second end sheet includes venting features, the venting features including holes or slots to channel heat, gas, or vapor during a brazing process.

Control assembly fabrication via brazing

A heat exchanger brazing fixture including a baseplate including a first surface and a second surface located opposite the first surface and a first post including a first end and a second end located opposite the first end. The first post is operably associated with the first surface of the baseplate at the first end. The A heat exchanger brazing fixture further including a top plate operably connected to the first post and separated from the first surface of the baseplate by a selected distance. The top plate being configured to move in a first direction along the first post when a heat exchanger resting upon the first surface of the baseplate expands during a brazing process.
