Nitrogen reflow promises better solder joints, but does it justify the cost? This evidence-based guide breaks down what research shows about which defects nitrogen actually fixes, when air reflow works just fine, and how to calculate the real ROI before you spend. Test first, decide second.

Your reflow oven could be running cleaner joints and tighter process windows—but only if nitrogen actually makes sense for your line. This guide cuts through the hype with a practical decision framework covering defect data, oxygen targets, real costs, and when air reflow is the smarter choice. Let your production data, not vendor promises, make the call.
