Abstract:
The invention relates to a method for the manufacture of packaged components. The invention is based here on the problem of facilitating the application of covers with lateral dimensions that are smaller than the lateral dimensions of the functional substrate. For this purpose, a plate-like cover substrate is mounted on a carrier substrate. Then, on the uncovered side of the plate-like cover substrate, trenches are inserted, so that a composite part is obtained with the carrier substrate and individual covering parts that are separated from each other by the trenches, but interconnected by the carrier substrate. The covering parts of the composite part are connected with a functional substrate with a plurality of components. Then, the connection of the covering parts is dissolved with the carrier substrate, and the carrier substrate is removed, so that a composite is obtained with the functional substrate and a plurality of covering parts that cover functional areas.

Abstract:
A method for the homogeneous heating of semitransparent and/or transparent glass and/or glass-ceramic articles using infrared radiation so that the glass and/or glass-ceramic articles undergo heat treatment at between 20 and 3000° C., notably at between 20 and 1705° C. Heating is achieved by a component of infrared radiation which acts directly on the glass and/or glass-ceramic articles and by a component of infrared radiation which acts indirectly on said glass and/or glass-ceramic articles. The radiation component indirectly acting on the glass and/or glass-ceramic articles accounts for more than 50% of total radiation output.
