The key components of coating equipment include:
Vacuum chamber: The vacuum chamber is the core part of the coating equipment, providing a dust-free and low oxygen environment to reduce the impact of gas molecules on the coating process. It is usually made of stainless steel or special alloys and has good vacuum sealing performance.
Evaporation source: The evaporation source is used to evaporate coating materials and can be a resistance heating wire, electron beam evaporation source, or laser evaporation source. The evaporation source evaporates the coating material into a gaseous state at high temperature, and then deposits it onto the substrate to form a thin film.
Sputtering target material: Sputtering target material is a key component in magnetron sputtering coating equipment, made of the material to be coated. During the sputtering process, high-energy ions bombard the target material, causing its atoms or molecules to be sputtered out and deposited onto the substrate to form a thin film.
Substrate holder: The substrate holder is used to fix and rotate the substrate to ensure uniform deposition of thin films. The substrate rack is usually made of stainless steel or other high-temperature and corrosion-resistant materials, and is equipped with heating and cooling systems to control the temperature of the substrate.
Control system: The control system is used to monitor and control various parameters during the coating process, such as vacuum degree, temperature, current, etc. Control systems typically include computer control systems, sensors, actuators, and human-machine interfaces.
Vacuum pump: A vacuum pump is used to extract gas from a vacuum chamber to create the desired vacuum environment. Vacuum pumps can be mechanical pumps, turbo molecular pumps, diffusion pumps, etc.
Gas system: The gas system is used to provide reaction gas, working gas, and protective gas to meet different coating process requirements.
Cooling system: The cooling system is used to cool components such as vacuum chambers, evaporation sources, and substrate racks to prevent overheating.
Electrical system: The electrical system is used to provide power, drive, and control various components of equipment.
Security system: The security system is used to ensure the safe operation of equipment, including emergency stop buttons, safety door locks, overload protection, etc.
Through the above key components, the coating equipment can complete various coating processes and provide high-quality thin film products for different application fields. If you need to choose or use coating equipment, it is recommended to consult a professional or equipment supplier to ensure that your needs are met and to ensure safe and efficient production.
