We have seen leakage currents around parts that have high impedance. Evidently with a small amount of moisture, weak organic acids present in the flux residue can cause a low leakage.

With the added temperature peak associated to Lead free reflow is anyone seeing or concerned about the increased vapor pressure that may result from moisture entrapment in moisture sensitive components?

What do you mean by "near the pad of SMT component"? The end of the pad, side of the pad, or perhaps adjacent to the part body, between terminations? One solder ball per component, or many, perhaps of different sizes?

pretty much menaing Amol, that the balls are stuck to the board by flux and when you wash the flux the balls go away with it. If yopu are running no clean, then there will be no cleaning step and the balls will remain since the flux is basically unt

okay, very admirable, so you will need to answer the rest of the questions that were posed. Such as the actual profile, storage and handling, registration of paste, etc.... I would lean towards Chunks thoughts myself as well. Russ
