Aqueous cleaning solutions using saponifiers and surficants can sometimes be used to clean NC flux residues. Search the fine SMTnet Archive for background and supplier suggestions.

KS: You're correct. The standoff on a 1.00mm and 1.25mm BGA is high enough to allow cleaning. The standoff on 0.8mm BGA does not allow proper cleaning, even with saponifiers.

We've only seen it done by accident, and the result was a lot of white flux residue. You do need to make sure you get it all off, and to do so most likely means using a saponifier like sara suggested.

We are using an inline aqueous washer with saponifier to clean smt assemblies with rosin based no-clean solder paste. Looking for a reliable, cost-effective way to monitor the cleanliness of the assemblies after cleaning. Any recommendations?

You need to switch to an alcohol based stamp. It will work cause that's what we use.

Depends on $$$ 1. Austin American 2. Stoelting 3. Technical Devices 4. Many more smaller companies. Many of the small machines are used with Saponifiers / Detergents. Not sure what your needs are but you should be able to find what you are looking f

I would recommend some sort of saponifier that has been tested and is known to remove the no clean flux residues that you're trying to remove.
