Less Oxygen... Less Oxidation Less Oxidation... Better Solderability

In addition to reducing oxides my understanding is that nitrogen increases the surface tension of solder (I've also read the inverse).

Bottom line, Nitrogen reduces rework, improves quality, improves solder appearance, and reduces maintenance.

Nitrogen increase surface tension in solder. This also reduces solder balls.

On our Pilarhouse Jade we use nitrogen to cool the belt that drives our solder pump as well as keep the amount of oxygen to a minimum in our solder pot to reduce dross.
