Cleanroom Certification in Phoenix, AZ

The Phoenix metro has become one of the country's most active semiconductor fabrication corridors, with major new fab construction and expansion driving sustained demand for high-classification cleanroom verification. GENTAB certifies cleanrooms and controlled environments for facilities across the Phoenix area to ISO 14644 standards, bringing the same nationwide certification methodology used in fab, healthcare, and industrial environments elsewhere in the country.

Semiconductor cleanrooms leave little margin for airflow or filtration drift, so our testing covers particle classification, ULPA and HEPA filter integrity, airflow uniformity across unidirectional flow zones, and pressure-differential mapping between adjacent process areas. We support new-fab commissioning, tool-environment requalification after changes, and scheduled recertification, with documentation built to withstand internal quality review.

Airborne Particle Classification: Particle count measurement and statistical analysis to determine and document ISO 14644-1 cleanliness classification at rest and in operation.

HEPA / ULPA Filter Integrity Testing: Aerosol challenge (PAO) scanning of installed filters and housings to detect leaks, bypass, and media damage before they compromise the space.

Air Change Rate & Recovery: Supply airflow measurement, air change rate calculation, and recovery testing to confirm the room clears contamination within its required time.

Room Pressurization Verification: Differential pressure mapping across doors and adjacencies to confirm correct cascade and protect critical spaces from cross-contamination.

Airflow Visualization & Uniformity: Smoke studies and velocity uniformity testing for unidirectional flow zones, documenting that airflow patterns sweep contaminants as designed.

Certification Documentation: A complete, audit-ready certification package referencing test methods, instrumentation, acceptance criteria, and pass/fail results per room.
