Abstract
This disclosure relates to a method of manufacturing an electrically conductive thick film comprising steps of: (a) applying a fine silver particle dispersion on a substrate, wherein the fine silver particle dispersion comprises, (i) 60 to 95 wt. % of fine silver particles, wherein particle diameter (D50) of the fine silver particles is 50 to 300 nm, (ii) 4.5 to 39 wt. % of a solvent; and (iii) 0.1 to 3 wt. % of a resin, wherein the glass transition temperature (Tg) of the resin is 70 to 300° C., wherein the weight percentages are based on the weight of the fine silver particle dispersion; and (b) heating the applied fine silver particle dispersion at 80 to 1000° C.
