| titleOfInvention | Aqueous acid solutions for the electrodeposition of tin and/or lead/tin alloys |
| abstract | Aqueous, acidic solutions for the electrolytic deposition of tin and / or lead / tin alloys are described for improved galvanic deposition in the high current density range and uniform gloss scattering of metals deposited in the low current density range. The solutions according to the invention contain a mixture of metal salts, free alkanesulfonic acid, non-ionic wetting agents and optionally aromatic short-chain aldehydes and / or optionally aromatic ketones and / or optionally short-chain unsaturated carboxylic acids. The solutions according to the invention are characterized in that tin and / or lead salts of alkanesulfonic acid are used as the metal salt, the alkyl group of alkanesulfonic acid consisting of 1 to 5 carbon atoms, free alkanesulfonic acid having alkyl groups with 1 to 5 carbon atoms and as a further brightener a mixture of a reaction product of acetaldehyde and / or its aldol condensation products with ammonia and / or acyclic ketones and / or aliphatic amines, amides, amino acids and / or hydrazine compounds is contained. |
