Cleaning of residues that were intended to be no-clean can really cause problems. In one DOE we found that about 90% of the residue came off, but the remaining 10% had a very high level of imbedded ionic content. The latter condition was much worse for SIR and other testing than the original residue. Things that we tested that I would recommend for you to also test on your process included Aquasonic from JNJ, Envirogold, and the Kyzen product Kathy mentioned.
