ABSTRACT:
A method and apparatus for cleaning printed circuit boards are provided. The method includes providing a cleaning apparatus with a housing having a conveyance mechanism for carrying printed circuit boards through the housing. The cleaning apparatus has at least a prewash station, a wash station and a final rinse station therein. The printed circuit boards are carried on the conveyance mechanism to the prewash station. A plurality of fluidic oscillator nozzles of the prewash station are utilized to direct liquid onto the printed circuit boards. Each fluidic oscillator nozzle outputs a stream of liquid with an instantaneous direction that oscillates back and forth relative to a nozzle axis over time.
