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.
