  • Acidic aqueous silver-nickel alloy electroplating compositions and methods
    Patent number: 11242609
    Abstract: Silver-nickel alloy electroplating compositions and methods enable electroplating silver rich silver-nickel deposits which are bright, uniform and have a relatively low coefficient of friction. The binary silver-nickel alloy is deposited from an aqueous acid silver-nickel alloy electroplating composition. The aqueous acid silver-nickel alloy electroplating composition includes thiol compounds which shift the reduction potential of silver ions toward the reduction potential of nickel ions such that a silver rich binary silver-nickel layer is deposited on a substrate.
    Type: Grant

    Date of Patent: February 8, 2022
    Assignee: ROHM AND HASS ELECTRONIC MATERIALS LLC
