The passivation process SILVERBRITE W ATPS is a water-based tarnish preventer for silver(<xr id="fig:Typical process flow for the SILVERBRITE W ATPS process"/>). It is free of chromium(VI) compounds and solvents. The passivating layer is applied by immersion, which creates a transparent organic protective film which barely changes the appearance and only slightly
increases the good electrical properties such as for example the contact resistance. The good solderability and bond properties of silver are not
negatively affected. Because of its chemical composition, this protective layer has some lubricating properties which reduce the insertion and withdrawal forces of connectors noticeably.
