<p>SOLID ELECTROLYTE CAPACITOR PROCESS The conventional silver contact layer of a solid-electrolyte capacitor is replaced with a layer of colloidal carbon containing a metal which is more electropositive than a solderable metal which is to be deposited as an electrical contact. The carbon layer is contacted with a salt solution of the solderable metal whereby the metal of the salt solution is chemically replaced by the more electropositive metal so that the solderable metal plates out on the carbon surface to form the desired solderable contact layer. The salt solution is preferably a copper or nickel salt solution, and the more electropositive metal is preferably iron.</p> |
