    Abstract: A ceramic substrate comprises a plurality of ceramic sheets, a plurality of inner conductive layers, a plurality of vias, and an upper conductive layer. The ceramic sheets are stacked one on top of another and include a top ceramic sheet. The inner conductive layers include electrically conductive material that forms electrically conductive features on an upper surface of each ceramic sheet excluding the top ceramic sheet. The vias are formed in each of the ceramic sheets with each via being filled with electrically conductive material. The upper conductive layer includes electrically conductive material that forms electrically conductive features on an upper surface of the top ceramic sheet. The upper conductive layer is constructed from a stack of four sublayers. A first sublayer is formed from titanium. A second sublayer is formed from copper. A third sublayer is formed from platinum. A fourth sublayer is formed from gold.

    Abstract: A solution comprising a palladium compound and a polyaminocarboxylic compound has been found to be suitable as a bath for electroless plating of palladium onto copper. Use of such a solution produces a plated component comprising a copper surface and a palladium plated coating having a thickness of between 0.01 micrometers (μm) and 5 μm. A method for electroless plating of palladium onto a copper surface of a component includes preparing a bath having a palladium compound and a polyaminocarboxylic compound. The copper component is submerged in the bath to plate a palladium layer on the copper surface of the component. The component resulting from the plating method has a palladium layer plated on the copper surface.
