Abstract
A gas exchange manifold includes a pair of plates which may be threadedly connected to one another. Gas supplying passages are formed through the plates to supply a desired gas to the package during fabrication. Also, vacuum supplying passages extend through the same plates and communicate with the package as well. A third plate, which may be sandwiched between other two plates, may contain a plurality of apertures which form part of the gas supplying passages. In this way, the third plate, which may be smaller, may be replaced to provide the desired pattern of apertures for a given configuration of packages being formed.
