Understanding Mixed Flowing Gas Tests Copper versus
· Mixed flowing gas (MFG) testing is used to demonstrate the ability of an electronic product or system to survive in a corrosive environment. MFG testing is designed to corrode copper and silver which are often used as electrical conductors in electronic products. However MFG tests have failed to identify issues in recent years. These failures have been predominately related to the corrosion

The development and performance characteristics of mixed
Abstract Three flowing mixed gases have been developed to achieve realistic simulation through the synergistic effects of (1) low concentrations of relevant pollutants (2) humidity and (3) temperature. The authors have demonstrated the importance of incorporating the sulfide-chloride synergisms into reproduced indoor field environments in order to simulate the observed corrosion response.
