Good afternoon!
We have had great luck with semi-aqueous cleaners from Kyzen and Zestron, and normally recommend both of them. They both have great labs and would gladly offer their input on he cleaning of the flux residue. We make sure that these companies have regular samples of our products to ensure that they can get it to class 3 requirements, no problem. More information can be found at knowledge.indium.com.
At the last Technical Presentation, I was amazed at the clean-ability of their products and how low the ppm of residue was left per their testing in ACI's (Philadelphia) IC test equipment. BTW, it was our latest NC Pb-Free material.
Should you have any further questions, please don't hesitate to ask. My contact information is below.
