Hi Jesper -
I thought you had inexpensive nitrogen (relative to the rest of the world) in
Denmark.
Regardless, though I am not a big fan of inerting the reflow process, it is a
different matter in wavesoldering.  I would think you could recover the cost
of the nitrogen through your savings in reduction of dross alone.  And it does
improve the surface tension of the solder to the interconnects.  Soltec has
some excellent papers on the subject as does Electrovert.  Contact them if
Seho can't give you some adequate data.
