Zusammenfassung: | Method of adjusting the resistivity of a thick-film resistor of the type made by screen printing on a substrate a composition comprising metal particles, glass frit, a temporary organic binder and a temporary solvent, drying to remove the solvent, and firing the composition to fuse the glass frit and burn off the binder, said method comprising determining the relationship between the resistivity of the fired composition and the drying time that elapses between screen printing the composition on the substrate and the beginning of the firing cycle, and setting this elapsed time in accordance with a desired resistivity value. |
