Process for soldering a current connecting element and a current feed conductor of a heatable glass pane
First Claim
1. A process for soldering a current connecting element to an enamel-like, electrically conducting layer burnt onto a surface of a glass pane, said electrically conducting layer being disposed on an enamel-like layer which is, in turn, located between the surface of the glass pane and the electrically conducting layer, said process characterized in treating the surface of the electrically conducting layer with a fluorine containing etching agent, said treatment being at the place provided for soldering, and soldering a foot of the current connecting element to said electrically conducting layer at said treated surface.

Abstract
A process for improving the solderability of a layer of a silver frit burnt onto a glass pane and a current connecting element wherein a layer of enamel is disposed and the surface of soldering and the glass pane. According to the process the surface is treated with a fluorine containing etching agent prior to soldering. The fluorine containing etching agent may be an aqueous solution of an acid fluoride, such as ammonium hydrogen fluoride or alkali hydrogen fluoride.
