PCE-66 Compact UV-Ozone Cleaner with 6″x 6″ Chamber for Effective Dry Surface Contaminant Removal
The PCE-66 is engineered to address the challenge of eliminating molecular and nanoscale contaminants from substrate surfaces prior to sensitive processes such as thin-film coating. It utilizes a dry cleaning method based on ultraviolet (UV) light-induced ozone oxidation, which effectively decomposes organic residues without wet chemicals. This approach is particularly beneficial for substrates like glass, ceramics, silicon, and other oxide crystals where surface cleanliness critically impacts subsequent processing quality.
Operation involves irradiating the substrate surface inside a 6″x 6″ (150 x 150 mm) chamber with UV lamps emitting at 254 nm and 185 nm wavelengths. These wavelengths generate reactive ozone and atomic oxygen species from ambient oxygen, initiating photo-sensitized oxidation reactions that break down hydrocarbons and other contaminants at nanometer thickness. The system includes an oxygen inlet port to enhance ozone generation and an exhaust fan with ducting to safely remove ozone gas from the workspace.

Hinweise zur Konfiguration und zum Betrieb
Replacement UV lamps are consumable parts and should be sourced separately as needed. The unit includes an LCD for setting cleaning duration and monitoring substrate temperature via a thermocouple sensor; however, it does not provide heating functionality. The oxygen inlet port allows connection to an external oxygen supply to enhance ozone generation efficiency. The exhaust fan must be connected to an external duct to safely vent ozone gas outside the facility. The sample tray features a locking mechanism to prevent accidental opening during operation, ensuring user safety. A buzzer signals the completion of cleaning cycles.
