. The advantage of this process is that the temperature is easy to control, oxidation is avoided during the welding process, and manufacturing costs are easier to control

. Including mesh belt, chain, rail 5. Nitrogen system. In order to prevent oxidation and increase wettability, the current reflow soldering often requires nitrogen protection, generally requiring an oxygen concentration below 1000 ppm 6. Electrical system

. (Some practitioners pre-bake components and boards to drive out moisture. This is not encouraged and should be a last resort as baking tends to build intermetallics as well as degrade the solderability by increasing oxidation levels

designed to combat oxidation and address issues with wetting. NWS has proven to handle the most difficult wetting/preparation tasks and has become widely accepted formulation on Flip Chip Bumping and Chip Scale Packaging sites

. Some Print Circuit board components is very small, easy to be oxidated in the high temperature environment, so need the nitrogen process to avoid oxidation on the solder surface

-remove protective layer and the antioxidant in the flux suppresses continued oxidation over time. Such effects help save the amount of activator needed for oxidation prevention, as well as the activator capping technique which allows maximum activation strength when the solder is molten
