Atmospheric Corrosion Tests on PdAg Thick Film Conductors

Atmospheric Corrosion Tests on PdAg Thick Film Conductors The influence of corrosive gases on the solderability of palladiumsilver thickfilm conductors has been investigated. An experimental setup for atmospheric corrosion testing has been constructed in which atmospheres can be created comparable to a heavily polluted industrial environment. Various PdAg thickfilm conductors have been submitted for 14 days to flowing atmospheres containing 1 ppm SO2, 15, 02 or 004 ppm H2S, 1 ppm NO2, 1 ppm O3 and 005 ppm Cl2, separately or in various combinations. When used separately, only H2S causes a poor solderability of the thickfilm conductors. This effect on the solderability turns out to be independent of the H2S concentration even concentrations as low as 004 ppm cause identical corrosion phenomena. The other gases mixed with H2S have a synergistic effect on the corrosion process. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Microelectronics International Emerald Publishing

Abstract

The influence of corrosive gases on the solderability of palladiumsilver thickfilm conductors has been investigated. An experimental setup for atmospheric corrosion testing has been constructed in which atmospheres can be created comparable to a heavily polluted industrial environment. Various PdAg thickfilm conductors have been submitted for 14 days to flowing atmospheres containing 1 ppm SO2, 15, 02 or 004 ppm H2S, 1 ppm NO2, 1 ppm O3 and 005 ppm Cl2, separately or in various combinations. When used separately, only H2S causes a poor solderability of the thickfilm conductors. This effect on the solderability turns out to be independent of the H2S concentration even concentrations as low as 004 ppm cause identical corrosion phenomena. The other gases mixed with H2S have a synergistic effect on the corrosion process.
