AlphaSTAR®

Immersion Silver

AlphaSTAR® immersion silver is the first and best tarnish-resistant immersion silver process that eliminates planar microvoids, while preventing creep and flaking corrosion. AlphaSTAR immersion silver meets the most complex lead-free assembly, end use performance and application requirements as mandated by the world's leading OEMs, PCB assemblers and fabricators. AlphaSTAR selectively deposits a high performance silver
coating that delivers high first-pass yields.
