    Abstract: A first die having a relief pattern is employed to provide predetermined shape and relative positioning for a first plurality of metal strips. A second die is similarly employed for a second plurality of metal strips Without removing the metal strips from the dies, the strips, still in predetermined shape and position, are bonded to opposing surfaces of an insulating substrate. The bonding process includes bringing the dies, and hence, the metal strips, into contact with the opposing surfaces of the insulating substrate. The bonding process may include the application of heat, pressure, and an electrical field across the bonding interfaces, e.g., anodic bonding.

    Inventor: FLECK HORST G

    Abstract: The invention herein described was made in the course of or under a contract or subcontract thereunder with the Department of the Army. An illustrative embodiment of the invention is directed to method and apparatus for manufacturing microchannel devices. Typically, individual glass tubes are suspended vertically in a furnace. A vacuum is drawn within the furnace so that the inner surfaces of the tubes, exposed to atmospheric pressure, will not collapse during heating and drawing. At temperature, the bundle is drawn in order to elongate and reduce the bundle cross section by a ratio of about 50 to 1. The elongated bundle is cut into lengths that are stacked together within a tube of glass that has a higher melting point than the glass in the drawn lengths. The channels are once more sealed and the adjacent hexagonal lengths are subjected to a secondary fusion process prior to slicing into thin discs. To prevent the inner lengths from cracking during cooling, the inner surface of the tube is treated with a fusion inhibiting compound (e.g., boron nitride).
