RK, what are you trying to remove? What are you trying to remove it from? And, what type of equipment do you have?
Generically, I suggest a saponifier, related to other aqueous chemistries, is associated with: -- higher PH -- need for effective chemical isolation from wash to rinse -- need to rinse really well -- higher temperatures and energy/$ -- wash bath turn-over --possible oxidation/discoloration/foaming concerns
A saponifier related to semi-aqueous and solvent chemistries has compelling advantages. If not needed, a saponifier related to water only has strong disadvantages. That said, with low standoff components and more challenging end-use demands, manufacturers are seeing the advantages of a cleaning chemistry out weigh the associated disadvantages.
One of my customer requested that their product shall be process utilizing no clean chemestries and washed utilizing appropriate saponifier and rised with DI water due to the high voltage of their assembly.
I wanted to convince my customer to use the normal lead-free water soluble flux process that normally does the job instead of the no clean with saponifier.
