Hi all, We have an Omniflow 7 reflow oven that has not come with the nitrogen option. We are looking at fitting a nitrogen system to the oven, does anyone have nay knowledge that may help us? The cost of the nitrogen is nothing as we outgas enourmou

Replacement for nitrogen in the reflow oven

Electronics Forum | Fri May 21 20:38:40 EDT 2004 | Grant Petty

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

How to measure N2 in reflow oven

Electronics Forum | Thu Mar 04 07:57:32 EST 1999 | John Godfrey

I need to setup an oven to run with a nitrogen atmosphere for boards with BGA's, but our ovens do not have the optional atmosphere monitor and controller. Is there a good way to sample and control the atmosphere without the optional built-in atmospe

All: All you using a nitrogen atmospheres with your lead-free waves? If not, why not, as I would think this might have benefits vis a vis reducing dross.

Nitrogen V.S Solder bridging problem

Electronics Forum | Sun Sep 09 10:53:05 EDT 2001 | bentzen

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

Minimizing Tombstoning Defects

Electronics Forum | Tue Sep 18 10:22:22 EDT 2001 | jschake

Paste Flux / Reflow: Our experiments indicated that the combination of no-clean solder paste and air forced convection reflow produced the fewest tombstone defects, followed by water-soluble paste reflowed in air, and most tombstones occurring with

I have attached a pdf version of an article that explains the basics of a nitrogen atmosphere when soldering. It gives some basic guidlines as to when one may want to use nitrogen and what it can and can not accomplish. FYI- I did not write that ar

Nitrogen Reflow Oven

Electronics Forum | Sun Apr 04 15:33:01 EDT 2004 | Jimmy

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
