An airflow visualization study, commonly called a smoke study, is the operational evidence that the cleanroom is behaving as the design intended. The qualification documents show that the filters are in spec, the pressure cascade is correct, and the air…
The 2022 revision of EU GMP Annex 1 made the Contamination Control Strategy (CCS) a single, auditable document. It is no longer acceptable to point to a set of SOPs and a cleaning rotation and call it a contamination program.…
Cleanroom cleaning and disinfection is the most under-documented control loop in most operations. Most programs inherit a rotation from the contractor who built the room, train two operators, and let the procedure drift. After two years the rotation has gaps,…
Garments and gowning procedures are the most under-engineered part of a cleanroom build. Most programs inherit a garment spec from a previous facility, train operators once, and assume the procedure holds. The data does not support that assumption — personnel…
Every cleanroom manager has lived through the same scene: a particle counter trips above its operational limit, the alarm hits the shift supervisor’s phone, and the next two hours are spent answering three questions in order — is this a…
Personnel are the single largest source of particulate contamination in any controlled environment. A technician walking from an ISO 7 gowning corridor into an ISO 5 process area can shed tens of thousands of particles per minute — skin flakes,…
Semiconductor Cleanroom Solutions · EU Procurement Insight Beyond the Equipment: Why Your Semiconductor Cleanroom Environment is Half the Solution A €374,676 wafer-cleaning contract at Silicon Austria Labs reveals what most procurement teams miss — the environment around the tool matters…
Why Particle Counter Selection Is the First Engineering Decision in a New Cleanroom If you walk into a newly built cleanroom and ask “is this room actually clean?”, the only honest answer comes from a particle counter. Not a smoke…
