Abstract:
The present invention is directed to an electroconductive thick film paste composition comprising Ag and a Pb-free bismuth-tellurium oxide both dispersed in an organic medium, wherein the paste is fireable at temperatures below 420° C. The paste is especially useful for forming electrodes on substrates such as glass or films, particularly electrochromic glass or films, that would be damaged by higher firing temperatures. The present invention is further directed to a device comprising an electrode formed from the paste composition and, in particular, to an electrochromic device comprising such an electrode.

Abstract:
A method of forming printed wiring boards having embedded thick-film capacitors includes covering capacitor layers with a protective coating prior to etching to prevent etching solutions from contacting with and damaging the capacitor layers and forming vias directly between the capacitor electrodes and the board circuitry.
