Surface Technology-Cleaning: CO2-Based Atmospheric Spray Cleaning and Surface Preparation: Technology, Applications, Equipment Configuration, and Operating Costs

Chicago, Illinois - CO2-based atmospheric spray technologies have been effectively used to meet a wide range of demanding precision cleaning and surface preparation applications.  CO2 sprays are made up of a mixture of solid CO2 particles, heated propellant, small concentrations of additives, atmospheric plasma, and combinations thereof.  Advantages of this no-touch cleaning technology include: dry non-condensing departiculation, thin film and fingerprint removal, and surface activation / functionalization of the surface.  The atmospheric spray technologies can used in selected open cell environments which are easily integrated into to a wide range of manufacturing workflow requirements.  These technologies have been effectively used in the surface preparation for automotive paint applications, HDD component cleaning, soot removal in medical device manufacturing, optical surface cleaning and surface preparation, and cleaning of wirebond surfaces on populated electronics boards.  
This presentation will be a summary of this CO2-based atmospheric spray technology cleaning capabilities including residue removal efficiencies, changes in surface energy from spray treatment, effective cleaning area of sprays, surface damage potential and other technical issues.  Furthermore, equipment configuration options, O&M costs, and lessons learned will be presented.
