Abstract
A vehicle window glass comprises a glass substrate layer, an electrically conductive layer forming a conductive pattern over the glass substrate, a lead-free solder layer on the conductive layer and a metal plate element of an electrical connector on the solder layer. Optionally a coloured ceramic band layer is sintered between the glass substrate layer and the conductive layer. The thickness of the metal plate element is between 0.5 mm and 0.7 mm.
Claims21
A vehicle window glass, comprising:
- a glass substrate layer, wherein the glass substrate layer is a soda-lime silicate glass defined by International Organization for Standardization (ISO) 16293-1;
- an electrically conductive layer forming a conductive pattern over the glass substrate layer;
- a lead-free solder layer on the electrically conductive layer, wherein the lead-free solder layer is made of a tin-based metal alloy comprising silver;
- and
- a metal plate element on the lead-free solder layer, wherein the metal plate element comprises iron alloy and has a thickness from 0.54 mm to 0.6 mm, and the iron alloy is Invar 48.
