The disclosed substrate structure includes a substrate body, a metal structure with a first finish area and a second finish area, a first surface finish, and a second surface finish. The metal structure is formed on a top surface of the substrate body, the first surface finish is formed over the first finish area of the metal structure, and the second surface finish is formed over the second finish area of the metal structure. The first surface finish is different from the second surface finish.
