3 Essential Methods for Measuring Chemical Concentration in Cleaning Baths
Controlling the concentration of cleaning baths is crucial for effective electronics cleaning. In this Ask Dr. Adam video, he’ll explore three methods to measure and maintain optimal chemical concentrations.
Dr. Adam will review the split method, which is ideal for non-homogeneous solutions and uses a simple beaker to measure the volume of separated phases. The refractive index measurement utilizes light bending properties, with higher bending angles indicating higher concentrations. And lastly, the sonic velocity method measures sound speed through the solution, comparing it to a calibration curve of known concentrations.
Dr. Adam will discuss how each method offers unique advantages for different chemistry types and applications, and some of the drawbacks of each method. Using these methods helps manufacturers maintain ideal cleaning bath concentrations, avoiding problems from incorrect concentrations and improving cleaning effectiveness in electronics production.
