Hi, This would be a very exciting idea. Nitrogen is an inert gas, so this is why it's used, however Hydrogen mixed with oxygen in normal air is highly explosive, so it would be one of the worst gasses to use in a reflow oven I would think. Remember

Hi SMTnet. I have a series of sensitive parts and solder preforms which degrade when exposed to oxygen and moisture. It seems the standard way of protecting these components is to use a nitrogen purged cabinet as storage. This seems to use a lot of

What is the guideline to determine the require level of PPM Oxygen in Nitrogen reflow.

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.

Nitrogen generators are becoming more popular than ever recently. They are being used for companies involved in food preparation, laser cutting and the electronics market to name a few. Purity, flow rates and pressure determine the system cost and va

Try Seho http://www.seho.de/index.php?id=2〈=en . At one time they had a machine that ran at near 0% oxygen (all nitrogen)that would solder without flux.

Hello reflow experts, I just wanted to know the effects of N2 and O2 on reflow furnace to the solder ball apperances. thanks in advance.... ...Omat

OSP is there to keep the copper from oxidizing. Once you wash the board, the copper is exposed. So, you have to either use it right away, or store it in a non-oxygen environment (vacuum/nitrogen).

We are looking at several reflow ovens with intent to acquire one for both air and nitrogen reflow capability (i.e. have the capability to reflow in either air or nitrogen environment). Would be interested to know what I should look for in comparing

Although pretty much standard these days, if you are planning on using Nitrogen, look for an on-board oxygen analyzer.
