A brazing fixture for fabricating a feed-through assembly during a brazing process and a method for forming a brazing fixture are provided. The brazing fixture includes a holding tray and a nesting plate removably mounted on the holding tray. The nesting plate has a surface with at least one nest disposed at the surface. The nest has a first well disposed at the surface of the nesting plate, the first well having first walls. A second well is disposed adjacent to and in concentric relationship with the first well, the second well having second walls. An orifice is disposed adjacent to the second well, the orifice having third walls. A release coating overlies the first walls of the first well and is absent from the third walls of the orifice.
