Transparent substrate provided with electrically conducting tracks.

摘要

The pattern of electric conductive tracks is screen printed onto the transparent substrate using stove burnt paste, the min. width of conductive tracks is less than 0.3 mm, pref. less than 0.25 mm. Pref. the substrate is a heatable glass plate, with printed conductive tracks of surface resistance of less than 2.5 mohm per square unit. The paste has an Ag of 50 to 88 percent and the conductive tracks rise 5 to 25 micron above the printed surface.
