Clean space temperature and humidity are mainly determined according to process requirements, but in the process to meet the required conditions, should take into account people's sense of comfort. With the improvement of air cleanliness requirements, process requirements for the emergence of increasingly stringent temperature and humidity trends. After specific process temperature requirements but also enumerated, but as a general rule, due to machining accuracy more sophisticated, so the temperature fluctuation range of demands smaller and smaller. For example, in the production of large scale integrated circuit lithography exposure process, as the thermal expansion coefficient of glass and the mask and the wafer requires smaller difference. 100 um diameter wafers Weifang decontamination offer, the temperature rises one degree, it caused a 0.24um linear expansion, so there must be a constant temperature ± 0.1 degrees, while requiring humidity is generally lower, because people sweat later, the product there will be pollution, especially sodium afraid semiconductor plant, which plant should not exceed 25 degrees. High humidity generated more problems. When the relative humidity exceeds 55%, the walls of the cooling water, condensation, if it occurs at precision devices or circuits, can cause a variety of accidents. Relative humidity at 50% rust. Further, the water molecules in the air through the dust adhered to the surface of the chemical adsorption of the wafer surface is difficult to remove the high humidity resistance. The higher the relative humidity Weifang decontamination Quote budget, adhesion is difficult to remove, but when the relative humidity is below 30% 2014 Weifang decontamination offer, and because the effects of static electricity so that the particles can easily adsorbed on the surface of Weifang decontamination offer, while a large number of semiconductor devices prone to breakdown. For optimum temperature range of wafer production 35-45%. For an object to control microbial biological clean room (example: biopharmaceuticals, clean operating rooms, sterile rooms, biosafety laboratory, experimental animal breeding sterile rooms, etc.) which focuses to control the generation and propagation of microorganisms, moisture and because Water is the microbial growth and reproduction conditions, water humidification watering, wet film, high-pressure spray and other methods can not be used in biological clean room, you can only use dry steam humidification and electrodes (electric) humidification.
