Electron optics is a discipline that studies the motion of electrons in electromagnetic fields and the focusing, imaging, and deflection of electron beams in electromagnetic fields. Currently, it is commonly used in industries such as semiconductors, precision manufacturing, liquid crystal manufacturing, optical manufacturing, and circuit board manufacturing. In order to improve production efficiency and reduce production costs, strict requirements are often placed on the production environment. Therefore, with the development of various high-performance electronic components and the practical application of manufacturing processes, there will be an increasing demand for production environment control. There are strict requirements for the environment of each region, such as temperature, humidity, cleanliness, and process flow. It is also necessary to consider power, lighting, pure water, water supply and drainage, anti-static, human and equipment grounding, anti microseismic, wastewater, compressed air, and exhaust emissions. There are corresponding standard specifications for these environmental parameters, which directly affect the qualification rate and service life of each product. Therefore, the clean workshop can provide the primary guarantee for product quality. Shenzhen Jinyundeng Engineering Co., Ltd. has been dedicated to the construction of purification workshops for 10 years, providing continuous support for the development of the electronic optics field.
