Precision Cleaning means cleaning to very exacting standards, with very low tolerance for left-over microscopic (<0.3 microns) particles or other contaminants. Components requiring the most stringent cleanliness standards are processed in heavily regulated air conditions that are similiar to those our clients operate their machines in.

In many high-tech precision industries such as semiconductor, digital display & storage media; Precision Cleaning is a prerequisite for newly manufactured parts prior to assembly, and a routine service and maintenance activity for delicate process equipment.

Dedicated Team
A dedicated division of qualified engineers and specialists are organized to respond quickly to the wafer fabrication plants' changing needs and can turnaround critical process kits at a short notice for our clients.

Confidentiality and Security
Safeguarding of our customer's confidential and proprietary information is our foremost priority. Corporate non-disclosure agreement is commonly practiced with our customers and our engineers/specialists may be required to enter confidentiality agreement before commencement of a project. We also have in place a strong data security system with controlled access that are monitored and controlled around the clock.

Customer Benefits:
• Assured service quality & response time
• Increased equipment availability
• Decreased wafer contamination & production cost
• Surface profiling for contaminant adhesion
• World class process kits recyling facility

Frontken Offers the following range of Precision Cleaning Processes:
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. Frontken cleans new and used components and assemblies, such as shields, platens, stainless liners, shutters, process chamber doors, transfer plates, rotating drums, process chambers, box coaters, CVD and PVD parts, load lock chambers, shielding, valves, ion sources, diffusion pumps, ion pumps, wave guides, etc., for the semiconductor, disk drive, medical, vacuum and related industries.
