Reflow Furnace
The function of the reflow furnace is to provide an evenly heated atmosphere to allow for the deposited solder paste to reflow (melt) to allow for connection of the SMT components to the printed circuit board. Convective heating is the most widely used method to provide for this heated atmosphere. Air or nitrogen can be used; however nitrogen is preferred to achieve lower soldering defects.

The reflow process of BGA and CSP components under a nitrogen (reduced oxygen) environment while using a low activity resin-based paste demonstrated better wetting performance than under an air reflow environment. Nitrogen reflow prevented the formation of new oxides, while avoiding the use of solder pastes with high fluxing capacity, providing improved wetting performance, fewer HIP defects, and improved quality and cleanliness of the solder joints, as compared to a conventional air reflow process.
