UV Ozone Cleaner System UV-312

  • UV Ozone Cleaner UV-312

The UV(Ultraviolet) -Ozone Cleaner removes molecular organic contaminants from workpiece surfaces and can also be used for surface modification via UV emitted at wavelength of 184.9nm and 253.7nm.


Surface treatment technology based on UV light is a dry cleaning which requires no vacuum system and can achieve a reliable cleaning effect without failure, and is further blessed with such a distinguished advantage that delicate workpiece surface suffer no damage. UV Ozone cleaner is also effective for pre-cleaning and post-cleaning / final cleaning in wet processes.


This simple system for dry cleaning requires no complicated structure and is the best used in final cleaning.

効果


Through UV ozone cleaning / surface modification by UV exposure, organic substances on the surface is removed. In other words, surface is changed from hydrophobic to hydrophilic.


You can observe it by changing of wettability through water drop.

Uses


Uses
1 Surface modification of resin sections.
2 Improved contactabilty, enabling better adherence, coating, printing, deposition, and soldering.
3 Improvement of work surface wettability.
4 For cleaning wafers, photomasks, glass substrates, lenses and optical components.

UV Ozone Cleaning Mechanism


Ozone generation Ozone is generated by oxygen in the atmosphere which absorbs the ultraviolet rays of 184.9nm.
Ozonolysis Generated-ozone generate oxygen and active oxygen to absorb the ultraviolet rays of 253.7nm furthermore.
Decomposition of organic matter Highly unstable active oxygen tied to organic compound and do oxidative decomposition such as H2O, CO2, and NOx.
