Abstract
An apparatus for sealing a substrate assembly by applying a force to the assembly while simultaneously exposing the substrate assembly, and in particular a sealing material disposed between two substrates of the substrate assembly, to an irradiating beam of electromagnetic energy. The beam heats, cures and/or melts the sealing material, depending upon the sealing material to form the seal. The force is applied by directing a flow of fluid against the substrate assembly, and beneficially improves contact between the substrates of the substrate assembly and the sealing material during the sealing process, therefore assisting in achieving a hermetic seal between the substrates.
