Abstract
This study extends the water drop test to allow for quantitative measurement of the electrochemical migration (ECM) behavior of several commercial solder fluxes. The technique developed affords a quick and approximate way to rank and select fluxes based on ECM propensity in applications where condensing humidity or ingress of liquids occurs in the use environment
