I recently commented on the effects of no-clean on our boards running at 622MHz. If I mentioned conductive, I apologize. I meant to say capacitive. The specific area affected on the board was a high impedance analog circuit. The no-clean residue caused a leakage path that acted like a capacitor. Hope this clears up some confusion.
