Disc comprising an electrical connection element

摘要

The invention relates to a disc with an electrical connection element, comprising: - a substrate consisting of glass (1), - an electrically conductive structure (2) with a layer thickness of between 5 µm and 40 µm on a region of said substrate (1), - a connection element (3) and - a layer of a soldering material (4) which electrically connects the connection element (3) to a sub-region (12) of the electrically conductive structure (2), - the connection element (3) containing at least one iron-nickel alloy or one iron-nickel-cobalt alloy, - the connection element (3) being connected over its entire surface to the sub-region (12) of the electrically conductive structure (2) by means of a contact surface (11), and - said contact surface (11) having no corners.
