A study was conducted to investigate the effects of temperature rate of change on the environmental stress screening (ESS) of printed wiring assemblies (PWAs). The related effects of chamber air velocity and temperature dwell time on module temperature response also were evaluated.Tests were conducted to investigate the effects of varying thermal cycling parameter levels. The effects of various chamber air temperature rates of change and velocity levels on the temperature responses of two vastly different PWAs were measured. A thermal cycling analysis of a PWA of the same construction as one of the two PWAs tested in the present investigation also was performed. A comparison of the results of a portion of the test was made with the analytical predictions.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
