A copper-gallium alloy is deposited on a nonconductive substrate, such as glass, ceramic, or polymeric material, to provide a conductor to which solder will readily adhere, such that electrical contacts to photonic and electrical components can be made. The copper-gallium thin film can also be used to provide a surface for solder sealing a component within a hermetically sealed enclosure. In a preferred embodiment, the copper-gallium alloy was from about 1 to about 40 percent gallium to about 99 to about 60 percent copper and was deposited to a thickness of from about 400 nanometers to about 3 microns. The copper-gallium film is deposited utilizing sputtering or electron beam deposition equipment.
