Do not 'ON" the nitrogen during reflow. If the pad of the chip is bigger then reduce the pad width from out side. Reduce the ramp rate at any point of the profile below 1 deg c/sec.

We are considering purchasing a Nitrogen generator rather than using a separate nitrogen tank outside the building. Here are my questions: 1. Has anyone out there used one before? Our model comes from Tamura and is priced around 50K 2. Would there be

| I am looking at purchaseing a full convection bench top oven from OK Industrys. (Model JEM-310) | It seems to have all the features that we will need for low volume production runs. | It has a Nitrogen input option, and I am intrested if anyone on

In my experiance, I have seen no difference in profiles between nitrogen and air reflows. What I understand is that the Nitrogen blanket allows for a greater solderability to gold plated pads. I also found that when dealing with fine pitch componen

Another benefit to low O2 levels with Pb Free is increased mobility of the alloy during soldering. It is an effective mobility enhancement in reflow as in wave soldering.

I am currently building boards which have to be conformal coated (done by an outside source) in a no clean process. The conformal coating however, must be applied to a clean surface. The flux residue left from the paste has come into question. I h

I need some advise from the reflow experts. In your experience in nitrogen versus air reflow, what would be the differences in profile parameters? For example, if I profiled a board in nitrogen and achieved (for a particular component) ramps rates un

I think the critical item is that you are soldering in a reduced oxy environment, lowering the rate of ongoing oxidation. Heat accelerates oxidation, lack of oxygen (of course) slows it down. The 10 Nitrogen soldering "myths" seem to be more like "

It's possible that N2 vogued at the dawn of the NC age. Once practitioners jiggered their profiles and more importantly, paste suppliers developed a decent product; the demand for inerts declined. Day-off sound like a fair trade.

kumar, can you explain why in zones 5, 6 and 7 you use different temperature on upper and lower heaters? Do you use a Nitrogen in your reflow oven?
