First Claim
Patent Images
1. A method of making a heatable vehicle window, the method comprising:
- forming a substantially transparent coating including at least one heatable layer on a glass substrate;
providing first and second conductive bus bars on the glass substrate over at least the coating, in a manner so that the first and second conductive bus bars are in electrically communication with the heatable layer of the coating;
electrically connecting an external conductive connector to one of the bus bars using a silver inclusive epoxy, and wherein silver content of the silver inclusive epoxy is from about 65-95%.

Abstract
A heatable vehicle window (e.g., windshield or backlite) has bus bars electrically connected to a heatable coating having one or more heatable conductive layers. Electrical connection(s) between at least one bus bar and a corresponding external connector in the heatable window is/are made using a silver inclusive epoxy. The use of the silver inclusive epoxy permits a thin substantially uniform electrical connection to be made and permits numerous example advantages to be realized.
