1. A pane comprising:
a glass substrate having a first coefficient of thermal expansion; an electrically conductive structure having a layer thickness of 5 μm to 40 μm on a region of the glass substrate; a connection element having a second coefficient of thermal expansion, wherein the difference between the first coefficient of thermal expansion and the second coefficient of thermal expansion is higher than 5×10−6/° C.; a layer of a lead-free solder material electrically connecting the connection element to a portion of the electrically conductive structure, wherein the connection element contains at least 55 wt.-% to 70 wt.-% iron, 30 wt.-% to 45 wt.-% nickel, 0 wt.-% to 5 wt.-% cobalt, 0 wt.-% to 1 wt.-% magnesium, 0 wt.-% to 1 wt.-% silicon, or 0 wt.-% to 1 wt.-% carbon, wherein the connection element is connected to the portion of the electrically conductive structure via a contact surface over an entire surface of the connection element, and wherein the contact surface has no corners.
