I may be wrong, but I'm thinking that nitrogen has less effect on solder bridging as does the amount of solder that is present. Nitrogen allows better wetting becasue there are no oxidation effects. If you have solder bridging problems, look at the

MarcA: Could you expand on the results you observed about improved wetting in a nitrogen environment? I am very interested to learn about the impact that nitrogen had. Was there an improvement in the cooling zone with nitrogen? Patrick

In addition to reducing oxides my understanding is that nitrogen increases the surface tension of solder (I've also read the inverse). Bottom line, Nitrogen reduces rework, improves quality, improves solder appearance, and reduces maintenance. Shea

We are using Nitrogen from Dewer tanks. We have purchased a generator from On-Site gas that we will be installing in 2 weeks. I guess Nitrogen purity could be an issue, but the company that sells us Nitrogen said it is five 9s (99.999%)

Contamination color is silver dust, like ash dust from burning wood. The pressure of nitrogen is 27 and the flow is 0.3. Do you know where can i find some documentation about nitrogen and fluxing?

We use Nitrogen to inert the Selective Solder, as well as spray flux. We have Onsite Nitrogen Generators.

we don't have a nitrogen generator installed yet. The solder wave supplier recommends 99.99%. we hare received several submissions for nitrogen generators that meet the requirements.

fluctuating PPM is not the Nitrogen if you are using liquid Nitrogen. It is the Oxygen. Your problem is not with the Nitrogen flow, it is Oxygen getting in your oven.

Thanks. I have another question. I believe this machine was originally set up to run nitrogen. In the cooling section there are two chambers. One with a radiator air/nitrogen knives and the other section/chamber has a blower. Instead of running nitr
