Hi Michael!
From experience, Kyzen Aquanox XJN works very well on no-clean residues.
Kyzen also has newer formulas such as 4512P and 4520 that works even
better at lower concentrations. Any of the Aquanox family cleans
no-clean residues very well...

Subject: [TN] Water Cleaning No Clean FLux from a PCBA
We have a PCBA assembly that requires very low/none ionic
contamination due to high impedance circuitry. Normally we use a water
soluble flux solder paste and wash the PCBAs. Our current vendor only
uses Indium NC-SMQ92 no-clean solder paste. To met the following spec:
Printed Circuit Assemblies shall meet cleanliness standards as per
IPC-A-610 and IPC/EIA J-STD-001.
Testing shall be in accordance with and meet the requirements of IPC/EIA
J-STD-001 Paragraph 8.3.6 or 8.3.7.
they want to use water and Kyzen XJN+ as a saponifier. Has anyone used
this method of cleaning a no clean assembly? If so what was the
result? Any other suggestions?
Thank you.
Best Regards,
Michael Forrester
