Palladium Electrodeposition from a Chloride Sulfamate Electrolyte

There is provided a bath for the electrodeposition of palladium. It is comprised of from 24 to 40 grams/1 of palladosammine chloride from 50 to 150 grams/l sulfamic acid, from 60 to 100 cc/l of ammonium hydroxide. The bath has a pH in the range of 8.7 to 9.3.

The above bath has a long-shelf life and provides bright plating over an extended current density range. The bath can be used for the palladium plating of SLT pins.
