We have been using nitrogen in our reflow ovens for many years to reduce oxidation on our solder joints. Management is concerned about the high cost of nitrogen and have suggested we use hydrogen instead. I'm not sure if this is a good idea, but we

Hello all, we use a reflow oven from Rehm in our SMT production. At the moment we solder under nitrogen atmosphere (approx. 500ppm). Now we want to reduce the nitrogen consumption (costs etc.). What consequences can occur here? Especially on the s

Nitrogen is helping voids, so if you have specific parts that are prone to voids, you might start seeing more voids. Joints will probably look a little dull in comparison and this might affect your existing AOI programs.

Hello Could I ask for advice? We have new machines with a full nitrogen tunnel. Type of soldering nozzle: worthmann 5 rows and next nozzle (in this same machine) worthmann 7 rows. One person in my organization claims that the delta nozzle is not wor

Helium is even more expensive than Nitrogen. How about Argon?

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

I'd guess any noble gas would be expensive.

As stated above, Hydrogen is EXPLOSIVE, very bad idea. Management might have meant HELIUM, also inert.

Let's not be hasty about the BTU, the Pyramax consums even more N2 than the Paragon that it replaced by something like another 40%! and the Electrovert aint that much better although it's been a while since I looked at them.
