Facing the yield rate and pollution sources, we have established a legal clean environment performance evaluation and diagnosis system.
Clean rooms have now become an important part of the production and experimental activities of high-tech enterprises, and "continuous pollution control" and fighting against particles have become an important task of clean room maintenance. As the environment (clean room) of the five elements of people, machines, materials, methods, and environment directly affects the yield rate of products, and the performance of clean rooms also directly determines the improvement of the enterprise's yield rate or the success of experiments. Providing a comprehensive and objective test and evaluation of the performance of the clean room can provide a useful reference for the maintenance of the clean room. The clean environment performance evaluation and diagnosis system is an important measure to promote the improvement of the clean room environment.
Based on the first-hand data of on-site testing and monitoring, and referring to the clean environment performance evaluation and diagnosis system, starting from the management, monitoring, maintenance and previous design, rectification and other aspects of the clean room, combined with the needs of the actual production department, a set of scientific, objective, fair, comprehensive and feasible performance evaluation and diagnosis indicators are provided for the series of problems existing in the current clean room. The cleanliness, ventilation times, pressure difference, airflow directionality, etc. of the environment are accurately and authoritatively tested to assess the pollution risk.
The clean room is composed of multiple systems, and the maintenance process is also the joint work of multiple professions.
Due to the declining product yield and the increasingly stringent standards such as GMP, the changes in equipment working conditions and the aging of equipment, the comprehensive performance of the clean room has gradually decreased, and some parameters no longer meet the design, specification and applicable requirements. Therefore, under the premise of reducing investment, meeting relevant needs and extending the service life of the clean room, implementing the comprehensive performance diagnosis of the clean room and starting to improve it is an economical and reasonable way to improve the clean environment. The detection of equipment and indoor parameter performance is a prerequisite for collecting on-site data. On-site investigation, testing and experimental research analyze its comprehensive operating status, identify existing and potential problems, and use them as the basis and data support for improvement. At the same time, improvement and rectification plans are proposed.
