Description

Verfahren zur Abscheidung von glatten und glänzenden Kupferüberzügen Die Abscheidung von glatten und glänzenden Kupferüberzügen aus sauren Kupferelektrolyten mit Hilfe von Kolloiden, Gelatine, Gummi, Melasse oder Phenol und seinen Derivaten oder oxyheterocyclischen Verbindungen wie Piperonal in Verbindung mit Moiybdänsalzen ist bekannt.Process for the deposition of smooth and shiny copper coatings The deposition of smooth and shiny copper coatings from acidic copper electrolytes with the help of colloids, gelatin, gum, molasses or phenol and its derivatives or oxyheterocyclic compounds such as piperonal in conjunction with Moiybdänsalzen is known.

Es wurde nun gefunden, daß bei Zugabe von dreifach ungesättigten Alkoholen zu einem sauren Kupferelektrolyten in Verbindung mit Thiophenol oder dessen Derivaten sehr glatte überzöge zu, erzielen waren und daß die Konzentration des Glanzbildners im Elektrolyten, in diesem Falle i, q.-Butindiol oder Propargylnlkohol oder einer Mischung beider im Gegensatz zu den bekannten Glanzbildnern, in bedeutend weiteren Grenzen gehalten werden konnte. Durch die Zugabe von Thiophenol und dessen Derivaten konnte in Verbindung mit dreifach ungesättigten Alkoholen eine wesentliche Glanzsteigerung der Kupferüberzüge erreicht werden. Außerdem war eine Erhöhung der Stromdichte im kalten sowie im temperierten Bade bei Anwesenheit von dreifach ungesättigten Alkoholen zu verzeichnen. Beispiel 25o g/1 Kupfersulfat, crist.It has now been found that when triunsaturated alcohols are added to an acidic copper electrolyte in connection with thiophenol or its derivatives very smooth coatings were to be achieved and that the concentration of the brightener in the electrolyte, in this case i, q.-butynediol or propargyl alcohol or one Mixture of both in contrast to the known brighteners, in significantly more Limits could be kept. By adding thiophenol and its derivatives was able to achieve a significant increase in gloss in connection with triunsaturated alcohols the copper coatings can be achieved. In addition, there was an increase in the current density in the cold as well as in tempered baths in the presence of tri-unsaturated alcohols recorded. Example 250 g / 1 copper sulphate, crist.

25 g/1 Schwefelsäure (66° Be) o,o5 g/1 Propargylalkohol o,oi g/1 Thiophenol.25 g / 1 sulfuric acid (66 ° Be) 0.05 g / 1 propargyl alcohol 0.1 g / 1 thiophenol.
