Hey Daniel, N2 gas provides an inert atmosphere which help to minimise oxidation, generally a concern across the reflow zone. Although N2 provides a more shiny solder joint, it is certainly more of a cosmetic issue and does not certify joint reliabil

N2 PPM vs %RH? With a firm grasp of the obvious, reflow oven manufacturers rig N2 ovens differently than non-N2 ovens. The N2 displaces O2. Usually N2 oven monitor something or other to give an indication of N2 ppm. %RH really isn't part of the eq

Rehm Thermal VX Series is the VW, Audi and BMW of reflow....Has features that enable best in industry process, lowest power and best N2 consumption should you run N2. Price is not cheapest on market but ROI has to be looked at in all areas not just

Hello all! We possess a speedline electrovert omniflo 7 reflow oven at my site. Last week we examined how the solder profile was affected by fan-speed and by providing the soldering process with compressed air(O2) or nitrogen(N2). We also ran the sa

I mean compressed air... But what is the difference between dull and shiny joints? Is it better electric conduct? Does the N2 obstruct voids i.e. ??? Thank you for your answers.

Been there, ... done that,...got the T-shirt. When with a major IC manufacturer, we tried this. IT DIDN'T WORK! The problem was that most convection ovens leak. We could not achieve a significant N2 atmosphere.Eventually went to vacuum-assisted bak

Like has been said, I would expect N2 to provide for shinier joints. On the other issue, which is it...O2 or compressed air? I would expect air to do nothing, and O2 might actually make your joints oxidize faster (duller appearance)...or blow up yo

Hello. I used Heller before - very stable oven, I had zero problems. Maintenance is also very easy. I also think they are not so expensive. You have to look at the power consumption and N2 if you are going to use it. Some ovens can trick you with low

Thanks John, You built smart batch I/R oven from a consumer toaster oven and that sounds pretty cool and cheap too. I'm hoping that we don't have to resort to all of that to get what we need... although I have been toying around with the idea of buil
