Title (EN) ORGANIC-METALLIC COMPOSITE COATING FOR COPPER SURFACE PROTECTION
(FR) REVETEMENT COMPOSITE ORGANIQUE-METALLIQUE POUR LA PROTECTION DES SURFACES DE CUIVRE
Abstract: front page image
(EN)Copper-containing surfaces (12) of substrates such as laminated electronic circuit boards (10) are protected by organometallic coatings (15) comprising organic compounds selected from the group consisting of benzimidazoles, alkylimidazoles, benzotriazoles and alkyltriazoles, substituted or unsubstituted, and metal particles (17) of solder-wettable metals or metal solders. The metal particles can be thermally formed $i(in situ) from metallic compounds such as noble metal acetates, acetylacetonates and carbonates.
(FR)Des surfaces cuprifères (12) de substrats tels que des plaquettes de circuits électroniques stratifiées (10) sont protégées par des revêtements organométalliques (15) comprenant des composés organiques. Ces derniers sont sélectionnés dans le groupe se composant de benzimidazoles, alkylimidazoles, benzotriazoles et alkyltriazoles, substitués ou non substitués, et de particules (17) de métaux mouillables par le bain de brasage ou d'autres métaux d'apport de brasage. Les particules métalliques peuvent être formées thermiquement $i(in situ) à partir de composés métalliques, tels que des acétates de métaux nobles, des acétylacétonates et des carbonates.
