Whatever you do, don't get a cleaner where they "lock" you into using their Saponifier! I remember at my previous company, getting that monstrosity running was my 1st project - the boob who bought it washed his hands of it and assigned it to me.....

Here are some answers to my questions after a good research. I also added more definitions that could help understand this esoteric language used in assembly, specially surrounding fluxes and their use. In blue italics are comments and extracts from

We do run them through an Aqueous washer, but I don't see excessive deposits or anything before washing. And our wash is just heated DI water.

Soon we will be manufacturing board assemblies on our SMT lines that will utilize both lead and lead free water soluable solder pastes. I have read some discussion about change-over from lead to lead-free jobs related to machine cleanliness, etc. H

Yea, that seems pretty obvious to me as well but we have a customer that's not buying into running lead-free in conjunction with lead. They strongly believe that we need to install a dedicated lead-free SMT line inclusive of in-line wash system. Th

Is there any harm in washing SMT soldered with NoClean paste? The PCA has some large thru-hole connectors that we would prefer to do as water soluble on out selective solder but the SMT consists of LGA's and other low parts that we would not be able

Sounds like a epididymis! It depends on your paste chemistry. You can't just slap any old saponifier in there. Most water based cleaners evaporate the water and you have to remove the dried paste. It's a bit messy, maybe that's why your's is over

I can't seem to locate any information/concerns about moisture entrapment in IC packages on the promary side in a double sided SMT assembly using water soluable solder paste when soldering the second side. A typical process would assemble/reflow/cle

You have a lot to think about! What does the flux manufacturer recommend as far as specifics like water temp or pressure? Do they recommend high temp di-water a detergent or saponifier? Do you currently have a cleaning machine, batch cleaner or inl
