ELECTROLYSIS BATH FOR ELECTRODEPOSITING SILVER-TIN ALLOYS |
摘要 |
The invention relates to an electrolysis bath for electrodepositing silver-tin alloys that, in addition to water serving as a solvent with a pH value of less than 1.5, contains a water-soluble silver compound, a water-soluble tin compound and an organic complexing agent. In order to obtain a stable electrolysis bath that enables the homogenous deposition of a compact tin-silver alloy with any type of composition, an aliphatic complexing agent having a sulfide group and an amino group is used as a complexing agent, whereby said functional groups are bound to different carbon atoms. |
