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.

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. -Carrie -----Original Message----- From: TechNet [mailto:[log in to unmask]]On Behalf Of Scott Lefebvre Sent: Friday, February 27, 2004 1:26 PM To: [log in to unmask] Subject: [TN] Use Nitrogen or Not! 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.
