I may be mistaken, but I thought that some of the no-clean flux residues were designed to accept conformal coating. Perhaps your flux manufacturer can shed some light...

Our management team wants the product to be absolutely free from any type of contamination. Has anyone had any experience with this? What are the possible advantages and some of the pitfalls we could anticipate? Are there any knowledge sources that you might be able to recommend? Any assistance would be sincerely appreciated.
