Hi everybody!

I was just wondering how much nitrogen folks are using in their low-residue wave
solder process. How many of your solder wave stages are you using nitrogen for?
I'm pretty much a solder wave newbie where I work. We're running nitrogen over
the solder pot only. I know that nitrogen is supposed to "open up" the process
window, which is especially critical with a low-residue (no clean) process.
Seems to me that just pumping it over the solder pot doesn't do much to open up
the window prior to soldering.

Any input is greatly appreciated. Now that I've actually asked a question I'll
have to try and come out of my lurker shadows a little bit more. :)

Thanks!
