<P>PROBLEM TO BE SOLVED: To provide a method of forming electrically conductive tracks on a transparent substrate, by screen printing with a conductive paste, and also provide the transparent substrate provided with the tracks. <P>SOLUTION: Track conductors with a length less than or equal to 0.3 mm are formed by applying, with screen printing, a thixotropic conductive paste whose ratio of the viscosity without shear stress to the viscosity under shear stress under screen-printing conditions is at least 50, whose silver content is greater than 35% and whose at least 98% of constituent particles have a size smaller than 25 μm, by means of a screen having at least 90 threads per cm, the coating of the screen being provided with slots the narrowest width of which is equal to 0.25±0.05 mm, and by subjecting the tracks to baking. <P>COPYRIGHT: (C)2013,JPO&INPIT |
