Abstract:
A method for forming a vacuum chamber comprising the steps of:providing an upper glass panel and a lower glass panel,providing at least two spacers in elongated shape with their upper ends removably clamped in a clamping fixture such that each of said spacers extends perpendicularly away from said clamping fixture at a predetermined distance from its immediately adjacent spacers,pressing said clamping fixture into and removing the same from a layer of adhesive such that the lower ends of each of said at least two spacers being coated with said adhesive,pressing said clamping fixture onto a top surface of said lower glass panel such that each of said lower ends of said at least two spacers intimately contacts said top surface of the lower glass panel,heating said clamping device, said at least two spacers and said lower glass panel to a temperature and for a time period sufficient to form an adhesive bond between said lower ends of said at least two spacers and said top surface of the lower glass panel,removing said clamping fixture from said upper ends of said at least two spacers, andmounting said upper glass panel to upper ends of said at least two spacers.
