Abstract

Beschrieben werden wäßrige, saure Lösungen für die elektrolytische Abscheidung von Zinn und/oder Blei/­ Zinnlegierungen zur verbesserten galvanischen Ab­ scheidung im hohen Stromdichtebereich und gleich­ mäßigen Glanzstreuung von im niedrigen Stromdichte­ bereich abgeschiedenen Metallen. Die erfindungsge­ mäßen Lösungen enthalten ein Gemisch aus Metallsal­ zen, freier Alkansulfonsäure, nicht ionogenen Netz­ mitteln und gegebenenfalls aromatische kurzkettige Aldehyde und/oder gegebenenfalls aromatische Ketone und/oder gegebenenfalls kurzkettige ungesättigte Car­ bonsäuren. Die erfindungsgemäßen Lösungen sind da­ durch gekennzeichnet, daß als Metallsalz Zinn- und/­ oder Bleisalze der Alkansulfonsäure verwendet wer­ den, wobei die Alkylgruppe der Alkansulfonsäure aus 1 bis 5 C-Atomen besteht, freie Alkansulfonsäure Al­ kylgruppen mit 1 bis 5 C-Atomen aufweist und als wei­ terer Glanzbildner ein Gemisch aus einem Reaktions­ produkt aus Acetaldehyd und/oder seinen Aldolkonden­ sationsprodukten mit Ammoniak und/oder acyclischen Ketonen und/oder aliphatischen Aminen, Amiden, Ami­ nosäuren und/oder Hydrazinverbindungen enthalten ist. Aqueous, acidic solutions are described for the electrolytic deposition of tin and / or lead / Tin alloys for improved galvanic ab divide in the high current density range and the same moderate gloss scatter from low current density area of deposited metals. The fiction solutions contain a mixture of metal salts zen, free alkanesulfonic acid, non-ionogenic network medium and possibly aromatic short chain Aldehydes and / or optionally aromatic ketones and / or optionally short-chain unsaturated car Bon acids. The solutions according to the invention are there characterized in that tin and / or or lead salts of alkanesulfonic acid who used the, wherein the alkyl group of the alkanesulfonic acid 1 to 5 carbon atoms, free alkanesulfonic acid Al has alkyl groups with 1 to 5 carbon atoms and as white tere brightener a mixture of a reaction product from acetaldehyde and / or its aldol condens tion products with ammonia and / or acyclic Ketones and / or aliphatic amines, amides, ami no acids and / or hydrazine compounds is contained.
