Anyone notice a change in the bath life of the Kyzen A4241 Saponifier recently?

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 che

We have inherited the need to monitor saponifier concentration and would like to avoid the need to perform titration testing and would obviously like to introduce continuous monitoring if possible. Is refraction commonly used as a measurement method

Probably 2) what is this white residue material (chemically )? => Natural or synthetic rosin 3) Can Saponifier wash, helps? If not what is the best solution to remedy this white residue. => Probably a saponifier will work. Some NC flux residues

In all likelihood, you may not be leaving flux on the board rather you may be leaving saponifier on the board. Improper rinsing is a leading cause of cleaning related board failures. The problem with some inline cleaning systems (especially old o

water alone especially cold is not good enough, how do you check for hasl fluids when most residues left behind after improper cleaning are non ionic. Use 40C saponifier followed by heated rinse then cold rinse then DI rinse followed by dry.Nylon bru

Various processes throughout the factory will use a stamp to signify ICT has been completed or QA has been done. The problem we are having is once the boards have made it through all the steps and have the stamps on them signifying who did what; the

Update - We've tested a board previously having voiding issues with ENIG versions and the voiding has completely disappeared. No other variables were changed. Looks promising. I have an order of LF HASL boards arriving soon that we plan to split i

Dream date? Would that be the St. Pauli girl? I like 'em built for comfort! Thanx for the reply. As usual, you are a fount of information and I will be checking the resource you mentioned. I haven't had much direct experience with saponifiers, now

But soon after cleaning and drying with IPA, we find a white residue formation. A: IPA will not nothing to clean your board. The white residue is exactly what you should expect. Search the fine SMTnet Archives for background. >How do we avoid th
