Nitrogen reflow sounds like the obvious upgrade, but it is not automatically better for every line. This guide cuts through the hype with real defect data, cost calculations, and a practical framework for deciding whether inert atmosphere actually pays back for your specific board mix. Measure first, decide second.
Buffer conveyors are the unsung heroes of modern SMT manufacturing. They act as temporary holding zones that absorb disruptions so your line keeps flowing when machines need maintenance or hit a snag. These “traffic roundabouts” for your PCBs decouple upstream and downstream processes, smooth out speed variations between equipment, and protect delicate components from damage. Choosing the right buffer means sizing from your actual interruption data and matching accumulation modes to your product requirements—not just picking something from a vendor brochure.
