There has not been a satisfactory way to determine the life or the effectiveness of the flux in the immersion solder process in performing its intended function. Techniques that are being used monitor the physical make-up of the solution, such as PH, percent EDTA, percent impurities, and viscosity. There has not been a strong correlation found between any of these parameters and the goodness of the flux.
