what was the product qualification material/process sets?  if it is the
same, you shouldn't worry, if it is not, selective re-qual might be needed.
If it is RF board, you might not allow to have any residue... it is all
depends... (Mr. SIR Doug Pauls has the authority on the issue).

Subject: [TN] Question about J-STD-001 cleanliness designator C-22


We are processing some assemblies with water soluble flux that requires
washing.   We then wash the assemblies as required by C-22.  The next step
we add a some hand soldered parts with no clean VOC flux but do not clean
the assembly. We sample test the boards for ionic contamination and they
pass.

Should these be considered compliant since they pass or would the no-clean
solder have to also be washed of.

FYI this is for some military work.

Any help would be appreciated
