Electronic dust-free cleanroom is suitable for industries such as semiconductor, microelectronics, electro-optical manufacturing, precision manufacturing, liquid crystal manufacturing, circuit board, etc. According to the manufacturing process and product precision, its purification grade is 100,000, 10,000 ,1000 and 100.
Basic structure of electronic dust-free cleanroom:
It is assembled by the ceiling and fence of the purification board site, and the inner walls are all arc-shaped. The aluminum profile is hemmed and sewed, and the epoxy artesian floor is used to avoid dust accumulation.
Cleaning principle of electronic dust-free cleanroom:
Air flow → initial purification → air conditioning → intermediate purification → fan air supply → air supply pipe → high-efficient purification air outlet → blowing into the room → taking away dust, bacteria and other particles → return air shutter → the initial effect purification can achieve the purpose of purification by repeating the above process.
In the production process of electronic products, environmental temperature and humidity, cleanliness and pressure gradient will have a great impact on the quality of electronic products. Therefore, it is necessary to have good heat insulation and air tightness, which is also reflected in the structure of clean workshop.
First of all, the structure must be as tight as possible. The cracks in the structure will lead to the convection between the treated clean air and the untreated air, which will affect the temperature, humidity and pressure gradient control in the cleanroom. Secondly, the selection of installation materials and structure of the cleanroom should achieve good thermal preservation effect as much as possible. For example, sandwich structures such as poly-atmosphere, rock wool and polystyrene can achieve good thermal preservation effect.
In addition, the use of heat-insulating color steel panel to form the enclosure of clean cleanroom can prevent the loss of cold and heat loads. This structural feature can well prevent the heat convection and conduction inside and outside the cleanroom. While saving the energy consumption of building air conditioning, it provides a good environment for the production of electronic products.
The production process of electronic products requires high precision of temperature and humidity, and the product quality is also very sensitive to the change of temperature and humidity. Therefore, in addition to good heat insulation and closed environment, clean factories should also be equipped with efficient and sensitive temperature, humidity and pressure gradient control equipment and automatic control system.
Clean workshop has the characteristics of multiple air changes and large supply of fresh air.
As a large amount of organic products such as heat, acid and alkali will be produced in the production process of electronic products, a large amount of waste gas is needed to maintain the normal process and technology, so as to prevent the indoor environment of the cleaning factory from being polluted and affecting the quality of electronic products.
Therefore, it is necessary to equip process ventilation devices with various performances to meet different types of ventilation requirements and achieve good ventilation effect to ensure a suitable production environment. At the same time, in order to ensure the cleanliness of the cleanroom, the air exchange rate of the circulating air in the clean workshop should reach a certain level. Tightness of enclosure structure, cleanliness of clean room, effectiveness of temperature and humidity control and quality of electrical equipment are important indexes of clean room, which will affect the quality of electronic products produced and stored indoors. Therefore, in the construction process, special attention should be paid to the construction quality of these aspects to ensure that the clean workshop can provide a suitable environment for the production and storage of electronic products.
