Claim:
1. A polymer thick film conductor composition, comprising: (a) 30-90 wt % of a conductive powder comprising silver powder and up to 1 wt % of the total composition additional metal powder or conductive carbon powder; and (b) 10-70 wt % organic medium comprising 10-60 wt % thermoplastic vinylidene difluoride/hexafluoro propylene copolymer resin dissolved in 40-90 wt % organic solvent consisting of triethyl phosphate, wherein the weight percent of said thermoplastic vinylidene difluoride/hexafluoro propylene copolymer resin and said triethyl phosphate organic solvent are based on the total weight of said organic medium; wherein said conductive powder is dispersed in said organic medium, wherein the weight percent of said conductive powder and said organic medium are based on the total weight of said polymer thick film conductor composition, and wherein a polymer thick film conductor can be formed by drying the polymer thick film conductor composition at a temperature less than 90° C.
