The cleaning method includes the oscillation of one or more workpieces in the cleaning tank to perform the rinse clean.
Claims9
A method, comprising:
- submerging one or more workpieces in a rinse tank containing a cleaning liquid;
- oscillating the one or more workpieces to remove at least a portion of the one or more workpieces from submersion in the cleaning liquid while generating a cross flow of the cleaning liquid in the rinse tank to generate tunnel flow shear cleaning of the one or more workpieces without sonicating the one or more workpieces.
