Abstract

The susceptibility of silver to sulfidation attack has been a continuing issue for the reliability of surface mounted resistors exposed to sulfur-bearing atmospheres. Some new conformal coatings have been developed to protect these resistors when exposed to harsh environments. This paper will present data showing how the kinetics of silver sulfidation varies with temperature when exposed to sulfur-bearing environments such as flowers of sulfur (FOS). Examples of susceptible resistors failing in an FOS environment will also be presented as well as examples of how new conformal coatings can prevent sulfidation attack of silver.
