With the development of science and technology, the requirements of the electronic manufacturing industry are increasingly high. The production of the electronic manufacturing industry is inseparable from the clean workshop. What are the characteristics of the clean production workshop of the electronic manufacturing industry?
Characteristics of clean workshop construction in electronic manufacturing industry: Cleanliness grade requirements are high, air volume, temperature, humidity, pressure difference, equipment exhaust air is controlled as needed, illumination, clean and clean room engineering section wind speed must be controlled according to specifications or customer requirements, in addition to this kind of clean workshop engineering requirements for static electricity is particularly strict, especially for humidity, because too dry workshop is particularly easy to generate static electricity, resulting in electronic and circuit damage.
1. Noise level (empty state) in 10,000 class clean workshop engineering of electronic manufacturing plant: should not be greater than 65dB(A).
2, electronic manufacturing workshop clean workshop engineering, vertical flow ratio should not be less than 60%, horizontal unidirectional flow should not be less than 40%, otherwise it is local unidirectional flow.
3. For the clean workshop engineering of electronic manufacturing plant, the static pressure difference with the outdoor should not be less than 10Pa, and the static pressure difference between the clean area and the unclean area with different air cleanliness should not be less than 5Pa.
4. The amount of fresh air in the 10,000 class clean workshop project of the electronic manufacturing industry should be the limit in the following two items: (1) The sum of the amount of fresh air required to compensate the indoor exhaust air volume and maintain the indoor positive pressure value; (2) Ensure that the fresh air quantity per person per hour in the clean room project is not less than 40m3.
5, electronic manufacturing industry clean workshop engineering purification air conditioning system heater should be set up, over temperature power off protection, if the use of point humidification, should be set up no water protection, cold area fresh air system should be set up anti-freezing protection measures.
6. The air supply volume of the clean workshop in the electronic manufacturing industry should take the following three limits: ensure the air supply volume of the clean workshop in the electronic manufacturing plant; According to the heat and wet load calculation to determine the air supply volume of the electronics factory clean workshop project; The amount of fresh air supplied to the clean room works of the electronics manufacturing plant.
