text: wave soldering?   wave soldering is a process in which a printed circuit board is passed over a wave of molten solder.  the wave is produced by a pump.  as the circuit board is passed over the wave, the solder bonds the printed circuit board paths with the board mounted components.  process characteristics   produces clean and reliable solder connections   is an automated process   reuses excess solder and flux   requires work inspection, touch-up, and testing   increases productivity through speed and efficiency
