~ The inspection of semiconductor components before leaving the factory must be carried out under certain humidity conditions, so that the detected data is more accurate. Humidity is also important for LCDs, and LCD screens must not be static during the production process. Static electricity can damage the pixels of the LCD screen. If a pixel on an LCD screen clicks through, the entire LCD screen is considered defective or directly scrapped. All the previous work has been abandoned, so it can be seen that the impact of static electricity on the LCD cannot be ignored. In addition, the screen printing workshop of the PCB circuit board must also maintain a certain humidity, and sufficient humidity screen printing ink can effectively adhere to the surface of the PCB board. Some ICs must not have static electricity, so the packaging must be anti-static packaging, so it is necessary to eliminate static electricity during IC testing. The test room must strictly control the humidity to minimize the occurrence of static electricity.
Penghao Dongyuan ultrasonic humidifier is also widely used in the production of LCD screen backlights. It is important to control dust during the production of backlight products. After installing DYJ series humidifiers, it can effectively reduce dust and remove static electricity to improve output. Penghao Dongyuan humidifier is installed Convenient and simple operation to serve all kinds of electronics factories and testing institutions, and is highly praised by customers.
The machine has a fast humidification speed and can reach the humidity required by the space in a short time. It is installed in a pipeline distribution to make the humidity in the workshop even. When the humidity of the workshop reaches about 70%, the suspended dust in the air will fall, thereby playing a role in reducing dust.
Humidity control is an important condition necessary for the production of clean rooms. Relative humidity is a commonly used environmental control condition during the operation of clean rooms and clean rooms. Typical target values of relative humidity in clean rooms and clean rooms of semiconductors are controlled in the range of 30 to 50%, and the tolerance is within a narrow range of ±1%, such as photolithography area or in extreme ultraviolet treatment (DUV ) The area is even smaller and in other places you can relax to within ±5%.
Relative humidity in the range of 40% to 60% is also a moderate range for human comfort. Excessive humidity can make people feel stuffy, while humidity below 30% can make people feel dry, skin rupture, respiratory discomfort and emotional discomfort.
The high humidity actually reduces the static charge accumulation on the surfaces of clean rooms and clean rooms-this is the result everyone wants. Lower humidity is more suitable for charge accumulation and becomes a potential destructive source of electrostatic discharge.
When the relative humidity exceeds 50%, the static charge starts to dissipate quickly, but when the relative humidity is less than 30%, they can persist on the insulator or ungrounded surface for a long time.
