Abstract
A method for obtaining a glazing includes a glass sheet covered, on one of its faces with electroconductive patterns having in at least one area, a so-called extra thickness area, a greater thickness than in the other areas, the method including depositing by screenprinting a first electroconductive layer forming patterns on one side of the glass sheet, then depositing by a digital printing technique, in the or each extra thickness area, a second electroconductive layer on the first layer while the latter is still wet, then a heat treatment step to cure the first and the second layer.
Claims13
A method for obtaining a glazing comprising a sheet of glass covered on a face thereof with electroconductive patterns having in at least one area, forming an extra thickness area, a greater thickness than in other areas of said face, the electroconductive patterns comprising heating wires and one or more busbars, said method comprising depositing by screenprinting a first electroconductive layer forming both said heating wires and said one or more busbars on said face of said glass sheet, followed by depositing by a digital printing technique, in the at least one extra thickness area, a second electroconductive layer on the first electroconductive layer while the first electroconductive layer is still wet, then performing a heat treatment step to cure the first and second electroconductive layers,
- wherein the extra thickness area encompasses a soldering area, and
- wherein the method comprises an extra step of soldering at least one connector to at least part of said extra thickness area.
