Abstract

In semiconductor applications, flux baths of ethyldiaminetetraacetic acid (EDTA) and glycerine used to prepare tin surfaces for soldering degrade and unreliable soldering takes place. The degradation can be measured by suspending a tin sample in the bath during use and recording the weight at equal time intervals.
