Vacuum Processing Systems has developed Vacuum Cycle Nucleation (VCN), an immersion process suited to both aqueous and solvent-based cleaning in which the pressure in a controlled process chamber is modulated above and below the vapor pressure of the cleaning solution, causing millions of small bubbles to form and burst at contamination sites on the surface of submerged parts. This causes the particles to detach from the surface. This growing and collapsing of bubbles is repeated approximately 60 times per minute by modulating the vacuum and pressure cycle.

According to the company, the VCN process has been shown to be non-damaging to surfaces and requires lower chemical concentrations to achieve the desired level of cleanliness. The vacuum nature of the process also assures that cleaning takes place in difficult-to-reach areas.
