Related technical indexes of electronic workshop class 10000 clean roomTo make the cleanliness level of the electronic clean room meet the appropriate requirements, air volume, temperature, humidity, differential pressure, equipment exhaust, etc. Should be controlled according to the requirements of the clean room illumination and cross-section wind speed should be controlled according to the design or specification. At the same time, the electronic class 10,000 clean room has strict requirements for static electricity. Too dry a workshop is prone to static electricity, which can damage CMOS integration. Taking the electronic class 10,000 clean room as an example, the relevant technical indexes of electronic manufacturing class 10,000 clean room are as follows:1. The noise level of electronic manufacturing plant class 10,000 clean room (air state): not more than 65dB (A). 2. Electronic manufacturing plant class 10,000 clean room temperature should be controlled at about 22, with relative humidity between 50-60% (special clean room has relevant temperature and humidity regulations). 3. The full distribution ratio of the vertical flow class 10,000 clean room of the electronic manufacturing plant should not be less than 60%, and the full distribution ratio of the horizontal unidirectional flow clean room should not be less than 40%, otherwise it is a local unidirectional flow. 4. 10,000 clean room and outdoor static pressure difference should not be less than 10Pa, different air cleanliness of clean areas and non-clean areas of static pressure difference should not be less than 5Pa. 5. Electronic manufacturing 10,000 clean room fresh air volume should be taken in the following two large values: compensation for indoor exhaust air volume and maintaining indoor positive pressure value of the new air volume and the amount required. 6. According to the heat and humidity load calculation, to determine the electronic plant class 10,000 clean room air supply, to ensure that the clean room per person per hour, the amount of fresh air is not less than 40m. 7. electronic manufacturing class 10,000 clean room purification and air conditioning system heaters should be set up for fresh air and over-temperature power-off protection. If point humidification is used, waterless protection should be provided. In cold areas, the new air system should be protected against freezing. No matter what kind of dustless workshop clean room is designed based on the production process, it is generally based on a comprehensive assessment of the customer's list of selected equipment, comprehensive process, space, and other factors to determine which purification program to use, as well as the choice of purification equipment. To idealize the air treatment effect and reduce the noise, the 10,000-level clean room project generally adopts the combined air handling unit chiller plus high-efficiency air supply outlet program and recommends reasonable equipment selection for the customer according to the technically evaluated program. |
