Subject: Sulphur Dioxide corrosion testing acceleration factors
We are interested in any experience anyone has had in predicting the equivalent field life of small electronics assemblies as a function of long term exposure(weeks to months)in a controlled atmosphere of 25PPM sulphur dioxide. Relative humidity will be near 93%, and the temperature between 40C to 60C. The assemblies will be a mix of discretes and ICs, with some relays and switches. Ongoing functional testing will be conducted until failure modes emerge. The study will be an attempt to compare wax coated to unprotected product. Thank you.
