Cleaning.

Precision part cleaning to the cleanliness levels demanded by optical, semiconductor, and medical applications.

Cleanliness is a
functional requirement.

In optical and semiconductor applications, contamination — whether particle, hydrocarbon, or ionic — is not merely cosmetic. It degrades optical performance, causes yield loss, and can render assemblies unusable. Our cleaning processes are designed and validated specifically for these demanding standards.

Ultrasonic Cleaning

High-frequency ultrasonic cavitation removes particulate and film contamination from complex geometries, blind holes, and internal channels that cannot be reached by conventional methods.

Aqueous Process Cleaning

Multi-stage aqueous cleaning with pH-controlled baths and deionized water rinses removes machining oils, greases, and process residues from machined components.

Solvent Cleaning

Targeted solvent cleaning for specific contamination types — effective for removing persistent organic films and precision-critical surface preparation.

Clean-room Packaging

Cleaned components are packaged in particle-free environments using appropriate materials to maintain cleanliness during shipping and storage.

Cleanliness standards & validation

Cleanliness requirements are defined in collaboration with the client and validated using appropriate measurement methods — particle counts, residual contamination analysis, and visual inspection under controlled lighting conditions.

Particle counting
Optical particle counting to validate specified cleanliness classes.
Gravimetric analysis
Residual contamination mass measurement for process validation.
Visual inspection
White-light and UV inspection for surface cleanliness verification.

Cleaning is available as a standalone service for components machined externally, or as an integrated step within our complete manufacturing process. All cleaning results are documented and traceable.
