Abstract: 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.

Abstract: IN MOUNTING COMPONENTS SUCH AS CERAMIC CHIP CAPACITORS ON INSULATING SUBSTRATES SO AS TO MAKE GOOD ELECTRICAL CONNECTION WITH A CONDUCTING AREA OF THE SUBSTRATE, A SOLVENTLESS CONDUCTING COMPOSITION IS SCREEN PRINTED ON THE MOUNTING SURFACE AND THE CHIP IS PRESSED INTO THE COMPOSITION. THE COMPOSITION COMPRISES A LOW VISCOSITY LIQUID EPOXY RESIN, A HARDENER FOR THE RESIN, AND A RELATIVELY HIGH PROPORTION OF SILVER POWDER.
