Abstract
A transparent electroconductive window comprising an assembly element supporting a circuit portion electrically coupled to a novel self-soldering bus bar consisting essentially of particles of a finely divided highly electroconductive metal, such as silver, dispersed within a metal alloy having a fusion point between about 70.degree. C. and about 150.degree. C. A mixture of finely divided metal and of said alloy is applied to an assembly element along one or more lines in electrical contact with an electroconductive heating element carried by said assembly element. The one assembly element is assembled with other assembly elements to form a sandwich that is laminated at a temperature higher than the fusion point of the metal alloy to form a transparent electroconductive window having highly conductive, self-soldering bus bars formed along said lines.
