1. A method for laminating an assembled sandwich structure including a functional part and one glass article separated from an outer surface of the functional part by a laminating film, comprising:
pre-laminating and bonding of the laminating film to the functional part and glass article in a vacuum by applying electromagnetic radiation from opposite sides of said sandwich by applying radiation from the glass article side at a radiation level which has a wavelength that provides penetration through the glass article, the film and half of the functional part, and applying radiation from the functional part side that has a wavelength that provides penetration greater than or equal to a second half of the functional part, selecting and controlling radiation powers for both of these radiation applications whereby a temperature of both surfaces of the functional part and the glass article are equal during heating, selecting the level of said vacuum to be a minimal value whereby the boiling point of water in the film is achieved during the radiation heating and the temperature is lower than the temperature at which said film sticks to the adjacent glass article and the functional part, and decreasing said minimal vacuum level to prevent the boiling of liquid components other than water contained in said film while the film temperature rises to a final bonding temperature level that is selected whereby an appropriate adhesion between said functional part, said laminating film, and said glass article is obtained after cooling; and
cooling said sandwich structure from both sides whereby an equal temperature of both surfaces of the functional part is provided during the entire cooling process.
