WebA reflow oven is a machine used primarily for reflow soldering of surface mount electronic components to printed circuit boards (PCBs). In commercial high-volume use, reflow ovens take the form of a long tunnel containing a conveyor belt along which PCBs travel. For prototyping or hobbyist use PCBs can be placed in a small oven with a door. WebFigure 2. Pb-free Classification reflow profile according to IPC/JEDEC J-STD-020. Use of nitrogen — It may be essential to work in nitrogen if air leads to unsatisfactory solder joints due to increased temperature and oxidation of Pb-free solder; however, the majority of Pb-free solder pastes can be used in air.Nitrogen may be used if the solder joints do not have …
