Abstract
A cleaning apparatus and method for washing and rinsing electronic assemblies. The apparatus includes a single closable chamber for containing a single tank with attached ultrasonic transducers. Separate wash and rinse fluid circuits each are arranged to fill the tank, to drain fluid from the tank, and to recondition the fluid for reuse. To permit the safe use of combustible solvents, an inert gas purge system evacuates oxygen and combustible vapors from areas with potential electrical ignition sources.
