Based on the studies I did with the Massachusetts Lead Free Consortium
where we ran a large lead free design of experiment. We definitely saw
visually enhancements to the quality of the lead free solder joints when
Nitrogen was utilized at 100 ppm.
In this study Nitrogen contributed as much as 10% to the visual yields on
our lead free study.

Yes -- If you are upgrading equipment for Pb Free, definitely have the
option for Nitrogen added to the equipment. IF you choose NOT to use the
nitrogen, you can do so through the recipe. It will be easier NOT to use
Nitrogen when you are plumbed for it than to Try to use Nitrogen when you
are NOT plumbed for it.

I am looking at upgrading our Reflow and Wave Solder equipment for Pb free.
I wanted to know what the consensus is for the requirement of Nitrogen for
these two systems. It seems to depend on who you ask some say you will need
Nitrogen and others say no.
Thanks,
