Sterling is an immersion silver finish that provides exceptional solder joint strength, touchpad functionality, wire bondability, and in-circuit test compatibility. It offers benefits throughout the supply chain: fabricators receive a versatile and flexible solution that can be applied with either horizontal or vertical equipment; assemblers get a durable finish that performs through multiple heat excursions, and high yields due to complete flux and paste compatibility; and OEM's receive uncontested reliability and service life due to the resulting Cu/Sn solder joint. As immersion silver has become the market leading Pb-free alternative to tin/lead finishes, Sterling is what to choose when only the best will do.
