I might be wrong since I don't know this piece of equipment but I think ROL might be a better measure. For 63/37 it used to be 20 ppm ROL (residual oxygen level) was about what you needed for a reflow oven. This is to take full advantage of all tha

Do anyone know what is typical Nitrogen setting in Reflow oven and Wave oven.? in SCHF= Thanks

Try antitombstone paste or if you are using nitrogen back off on the amount of nitrogen used.

what does nitrogen do to assist the selective soldering process?

Nitrogen increase surface tension in solder. This also reduces solder balls.

For reflow soldering, you are correct ! The higher surface tension of the solder paste in nitrogen atmosphere can increase the number of solder bridges if the component or solder paste print is inaccurate. Another defect that might increase is tomb

I'm looking for evidence to support, or disprove, the use of Nitrogen in the reflow oven. I've heard many arguments on both sides. I have my own personal opinion. But I'm looking for scientific studies or white papers, specifically addressing the ben

Have any of you ever gone from using Nitrogen in your Reflow and Wave solder process to using only compressed air? No Clean users only please. I'd like to get away from Nitrogen if it makes sense.

Hi guy Please help advise me the impact of using Nitrogen to solder bridging defect. I heard somebody said that using nitrogen can effect the bridging problem by higher surface tension in case inaccurate printing . Is it true? Thanks.
