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.
