CO2 Snow Jet Cleaning

The CO2 snow jet cleaning process uses carbon dioxide to remove micron and submicron particles from surfaces at high efficiencies and also removes hydrocarbon based contamination. CO2 snow cleaning is nondestructive, nonabrasive, residue-free, and produces no chemical waste.

Applications

Many different cleaning applications have been successfully demonstrated:

• contamination removal from metals, ceramics, polymers, and glasses
• particle and stain removal from Si, InP, and GaAs wafers
• cleaning optics, i.e., coated lenses, laser, IR and UV optics, fiber optics
• sample preparation before surface analysis (Auger, XPS, SIMS) and AFM
• general laboratory, production, and cleanroom cleaning
• substrate preparation of all kinds
• cleaning vacuum systems components including electron and ion optics, bellows, machined parts
• removing particles from microelectronic and hybrid circuits
• restoration after fires, art restoration; telescopes; and many more
• telescopes, and many more

Equipment

Standard Units are the simplest and easiest way to get started. They can address both general and critical cleaning problems. These units come with either a 5 or 10 foot hose, a cylinder fitting, an on/off gun and two stainless steel nozzles: The asymmettric venturi is on the unit and the reduced flow nozzle in the directions. Solenoid control valves are available.

We also manufacturer a "large area" snow attachment to the standard unit. Here, a small tube nozzle (diameter of 0.035, 0.045, or 0.062) is placed within a 1 inch OD plastic tube. The high velocity snow is transformed into a lower velocity snow. These units are aimed for cleaning large optics of micron and larger particle removal.

High Purity Units are intended for critical cleaning applications. These units include a cylinder fitting, PTFE lined stainless steel flexible hose, a stainless steel packless valve, and two nozzles: the asymmettric venturi is on the unit and the reduced flow nozzle in the directions. Units can be equipped with 1/8" OD SS tubing in place of PTFE tubing - $100.00 extra. The K4-10S has a high pressure solenoid valve (24 VDC power supply and footswitch) with compression fittings substituted for the electropolished stainless steel packless valve. This allows for operation with only one hand. The K4 units are also available with VCR or VCO type fittings on the valve, K4-10VCR. The K4 units can be packaged to "cleanroom ready" standards - an additional $300.00; ask for details.

Variable Orifice Units can address both simple and general contamination control problems and also critical cleaning issues. There are two different variable orifice units - a standard one with a packed leaked valve with a polymer seal, and an all metal bellows metering valve. The standard variable orifice comes with a cylinder fitting, 10 foot PTFE lined stainless steel hose, a metering value with a variable orifice and 3 SS nozzles - inner diameters .05, .09, and .14 inches. The high purity variable orifice unit is made from an all metal bellows valve. The unit is equipped with a pressure gauge and an F3 filter (0.003 micron) as part of the price. This unit comes with a 10 foot PTFE lined hose. All connections are Swagelok - no PTFE tape or pipe thread fittings. Four electropolished nozzles can be supplied. The high purity variable orifice unit is similar to one from another company but at a reasonable price. Both units are equipped with a valve for manual on and off control (the metering valves do not seal). These units will come with an polymer handle and grip.

Dual Gas Unit is a modified High Purity Unit (K4-10S) with the optional nitrogen purge flow co-axial to the dry ice stream. Each flow is controlled by solenoid valves (foot activated or via circuitry). One footswtich controls the the CO2 flow, the other controls the nitrogen flow. This unit comes only with the asymmetrric venturi nozzle on the unit.
