ABSTRACT:
A surface cleaning apparatus and method is disclosed for disbonding, removal and collection of undesired matter from product surfaces, particularly in controlled process environments. The apparatus includes a negatively chargeable staging surface for receipt thereat of a product having a surface or surfaces to be cleaned, a gas stream nozzle having an electron generation source, usually a negative ion source, adjacent to its outlet, and a positive electrostatic field generator having a collector surface spaced from the staging surface. The electrostatic field generator may optionally include pulse generating circuitry for generating pulsations of selected frequency within the positive electrostatic field. Controls are provided for selectively controlling negative charge at the staging surface, ion output, field strength and, when provided, field pulsation frequency.
