  • Patent number: 7582833
    Abstract: The present invention relates to a method of manufacturing electrically conducting tracks on a transparent substrate, by screen printing with an electrically conducting paste, and to the transparent substrate provided with said tracks. According to the invention, conducting tracks are formed with a width less than or equal to 0.3 mm by applying, by screen printing, a thixotropic electrically conducting paste having a ratio of the viscosity without shear stress to the viscosity under shear stress under screen-printing conditions of at least 50 and having a silver content greater than 35% and of which at least 98% of the particles which form it have a size less than 25 ?m, by means of a screen having at least 90 threads per cm, the coating of said screen being provided with slots, the narrowest width of which is equal to 0.25 mm±0.05 mm, and by subjecting said tracks to baking.
