Mr. Brown,
It is next to impossible to give an idea of what the residue is without
knowing more about the background manufacturing process.
1. What flux technology was used: RMA, water soluble, no clean?
2. What cleaning process was used?
3. Is it a systematic problem or only a few rare occurrences?
4. What solvent is being used to remove the residue?
Providing the background history on the board will often aid the rest of us
in figuring out the problem.
