A cleanroom is crucial to electronic industry due to its extremely high sensitivity to the surroundings of the electronic products. Because of the high sensitivity of products, the cleanness of the cleanroom can directly affect the production pass rate of the manufacturer. Therefore, the air tightness from the HEPA filter unit enclosure, the pressurization between different rooms and particle concentration become significant amount all the cleanroom design factors.
For some manufacturing procedures, the electrostatic control can also be of much importance. The control of the anti-electrostatic performance involves an comprehensive cleanroom solution such as the floor construction, garment control, electrostatic discharge procedures and so forth. The production pass rate can be improved up to 70% if appropriate measurements implemented.
