In many critical applications commonly found in high-tech industries such as semiconductor, flat panel display, hard disk drive, aerospace and medical, precision cleaning is a prerequisite for newly manufactured parts prior to assembly, and for routine service and maintenance of manufacturing devices.

a)   Spray Cleaning
Spray cleaning involves delivery of a liquid cleaning agent to the surface through the use of a pump and nozzle. This same pump and nozzle arrangement delivers mechanical energy to the cleaning site as the stream of spray impinges on the surface. In general, spray cleaning is highly effective on any surface that can be “seen” directly by the spray. Different effects can be achieved by changing the pressure of the spray, the spray pattern and the volume of cleaner sprayed to provide more or less impingement on the part.

b)   Immersion Cleaning
Immersion cleaning involves immersing the part directly in a liquid cleaning agent. Immersion alone does not inherently supply any mechanical energy. Mechanical energy is supplied by a number of auxiliary means that may be used alone or in combination.

c)   Ultrasonic Cavitation and Implosion
Ultrasonic agitation uses high frequency sound waves create small cavities (bubbles) in the cleaning liquid that collapse (implode), releasing considerable energy. Due to the nature of the phenomenon, this action is mostly concentrated at the interface between the cleaning solution and the contaminant being removed. Ultrasonic waves can penetrate thin layers of metal and propagate around corners to clean work pieces inside and out.
