AN IMMERSION SILVER PWB SURFACE FINISH TO COMBAT HARSH ENVIRONMENTSAuthors: Ernest Long, Ph.D., John Swanson, and Lenora Toscano
Date Published: 10/4/2009 Conference: SMTA International
This paper presents detailed corrosion results for common surface finishes in both "industry standard" and "custom-designed" corrosion inducing environments. It is suggested that an improved understanding of the gaps between field and standardized test techniques may emerge from this work. Additionally, this paper focuses on demonstrating enhanced tarnish and corrosion performance for an immersion silver based final finish. A detailed review of the coating's confirmed functional and assembly performance, attained via a commercially installed system, is also provided.
