SnoBot
Flexible Automated and CO2-enabled Workcells
The SnoBot™ custom robotic cleaning series can handle substrates or fixtures up to 24 inches 
square, providing cleaning and surface modification like never before. Within the interlocked and exhausted enclosure, parts are thoroughly scrubbed with a CO2 composite spray to remove gross surface contamination. Momentum transfer blasts particles away while the instantaneous solvent power of liquid CO2 quickly removes thin film contamination. An optional powerful jet of BlueFire™ atmospheric plasma technology breaks the bonds of tough organics like a jackhammer with a microscopic combination of UV light, ozone, oxygen radicals and heat. A final pass with CO2 composite spray removes the remaining debris away, leaving a clean and high energy surface for bonding, coating, encapsulation, or underfill processes (which themselves can be incorporated into the SnoBot as well). Test results prove surfaces are prepared as good as or better than using etchants and dangerous solvents and without costly and time-consuming multiple processing stations. Your parts are ready for wire bonding, gluing, imprinting, assembly or other secondary operations where particle and residue cleanliness or increased surface energy improves operations.
Example Applications and Benefits
- Selective submicron particle removal from hard disk drive assemblies during precision assembly
- Create lean and green assembly cells – for example an adhesive bonding cell that provides dry selective CO2 composite spray surface cleaning, followed by a CO2 atmospheric plasma etch, and completed by a selective adhesive dispense and UV cure operation
- Cleaning with non-contact surface inspection
