Method for producing small, sheet glass plates and larger sheet glass plates as semifinished products for producing the former

Abstract

Small sheet glass plates (2) of this type with a predetermined geometrical structure are conventionally produced by being cut out of a larger sheet glass plate (1). The small sheet glass plates (2) that have been separated in this way, together with a jointing cement, in particular a solder frame (3) consisting of glass solder are then attached to other components, for example to be used in “electronic packaging”. In order to improve handling during the production and the jointing of the small sheet glass plates (2), the invention provides a larger sheet glass plate (2) which is patterned on both sides using a screen-printing or stencil-printing process and preferably using laser beam treatment along desired predetermined breaking points (5). Said larger glass plate can then be separated into smaller, patterned plates, i.e. the small sheet glass plates (2), whose shape is geometrically determined, by a simple preferably mechanical breaking process. A separation by an abrasive cutting-off process can also be carried out, if the larger sheet glass plate (2) is positioned on a supporting material.
