Hi all,

I have a few questions like to get the answer from the expertises:

1. Nitrogen being used on the wave process, what kind of process
improvement do we achieve? I heard people said that they have better
joint, better reflow.....
2. If it helps to reduce drossing of solder, how much solder do we save
monthly? How much dross produce/reduce each month? (Use % for
calculation).
3. How much nitrogen consumption in a month? (Let's say the machine runs
2 shifts in 22 days/month).

How can I measure/justify of using nitrogen in the process in terms of
quality and savings?
Your answer would be a great help for me.

Thanks

Simon Shin
