... soldering iron or in a molten flux bath at approximately 240 °C (465 °F). After soldering, it may be necessary to control the cooling to avoid cracking of the solder. Because the fluxes used are corrosive, it may be necessary to remove the residual flux. Undesirable holes can be filled with solder...

As the printed circuit board passes on the wave, the solder wets the surface-mount package leads, terminations, and exposed metal surfaces in the circuit board, and also fills plated through holes. This technique can produce several...
