What are the cleanroom purification needs of the electronics industry?
What are the cleanroom purification needs of the electronics industry?1. CleanlinessClean room cleanliness is the most important and most basic technical indicator of a clean room, the unit is: the unit volume of air in the particle size is not less than a certain scale of the number of particles. The electronics industry for the cleanliness requirements are generally higher, more than 100,000 levels, followed by the optoelectronics industry. 2. Temperature Temperature is the basic working conditions, almost all of the clean rooms for the temperature have clear requirements. Temperature affects the scale of the object, thus affecting the accuracy of the processing, so precision machining for the temperature has quite strict requirements. The temperature will affect the parameters of the instrument, thus generating measurement errors, so precision measuring instruments also have higher requirements for temperature. 3. Humidity Electronic clean room humidity is also a basic working condition, in general, the clean room for the humidity also has clear requirements. Excessive humidity will make many substances have chemical reactions, thereby reducing product yields, and even make equipment failure, and product obsolescence. Too low humidity will make many substances dehydrate and deform, and lose their original function. 4. Wind speed and air volume Enough wind speed and air volume is a guarantee of cleanliness, too large wind speed and air volume is not only a waste of energy, and sometimes affect normal work, the appropriate wind speed and air volume size ensure that the personnel work appropriately sense. 5. Air pressure and differential pressure Normal air pressure is the basic condition for normal work. The necessary differential pressure is a means to control the direction of air leakage. Clean room inside the clean level to rely on positive pressure to maintain the electronic industry to ensure the cleanliness of the clean room, do not allow low-clean air leakage to high-cleanliness areas, and similar virus laboratories or infectious disease rooms do not allow indoor air leakage to the outdoors. 6. Noise and illumination Excessive noise will not only affect normal work but also affect the health of personnel, reducing noise is a basic requirement of a clean room. Appropriate illumination is also a necessary condition for the normal work of the electronic clean room. |
