) vapor to act as a reducing agent to oxides on metal solder, replacing the need for flux. Eliminates issues related to residual flux, such as voiding Process steps related to flux, such as for pre-reflow fluxing and post-reflow flux cleanup steps are no longer needed, saving time, money, and floor space

. It robs solder from the interconnection, and is usually caused by uneven heating between the materials being joined. This is seldom observed in convection dominant reflow and was more a trait in older IR dominant reflow and vapor-phase technologies

. The standard says that the same footprint pattern can be used for reflow, infrared, vapor phase, full wave and selective wave solder processes.
