Patent ID: 7189343

Claim:
Use of a composition in the manufacture of an electrically-conductive pattern on a substrate comprising the following steps: applying a coating to a substrate of a composition comprising: (a) finely divided particles of an electrically-conductive material comprising a metal, wherein component (a) is present in amounts of 60 to about 90% by weight of the total solids present in the composition; (b) finely divided particles of one or more inorganic binders; and (c) finely divided particles of aluminum present in amounts of about 2 to about 15% by weight of the total solids present in the composition, wherein components (a), (b) and (c) are dispersed in a liquid vehicle and wherein the total amount of component (a), (b) and (c) is 50 to 95% by weight of the total composition and wherein the metal of component (a) together with component (c) constitute the total metal material of the composition, said total metal material being present in amounts greater than 35% by weight of the total solids present in the composition; then firing the coated substrate to effect sintering, whereby the composition possesses a resistivity in the range of 18.5 to 70 micro ohm while at the same time maintaining solder adhesion in the range of 16.3 to greater 20 W/kg.
