Does anyone have experience in N2 supply source for reflow oven (1000scfh) other than N2 generator? Tanks, liquid, etc. We are in the developement stages of lead free processing and would like a quick, short term solution for providing N2 to a Conceptronics HVN102 reflow oven. As economically as possible of course.

If economical is what your looking for the atmosphere already contains 20 odd percent nitrogen.

Why the need to use N2 with lead free?

The use of nitrogen in lead free wave solder operations is primarily used to reduce or even eliminate drossing of the solder, thus improving solder yield. The higher priced lead free solder makeup (Cu, Ag) make this a more economical proces than the old leaded solder systems. Nitrogen, on finicky to join parts, can "open up the process window" making any other variations in the process more forgivable. If excess drossing of lead free solder is not a concern and if parts are being soldered to quality specs, then nitrogen may not be necessary.
