I am doing my master degree in flux cleaning process for flip chip assemblies and required to establish a new receipt for flux cleaning. currently, i am doing screening process for the parameters involve ; temp,pressure, surfactants, speed and angle of penetration using inline cleaning machine.
Is there any other ways to evaluate the chemical compatibility for flux cleaning instead of directly tries it using the cleaner machine? It will be a waste to use lots of chemical just for screening. I have found a paper that use beaker-test-scale method for chemical compatibility (Cleaning RMA Flux residue in a high Lead Wafer bumping process), but it didnt state the details about the method. Have anyone try this method before?
Your help is much appreciated.
Thank you.
