In the manufacturing process of mobile phones, there are often residual organic pollutants such as oil, wax, fingerprints, and grease on the surface of optical materials such as glass covers, mobile phone covers, and displays. The existence of these residual pollutants is not conducive to the process of coating, spraying, printing, bonding, welding, etc. Therefore, these pollutants must be cleaned before the next step to ensure the quality of the subsequent process.

The ultrasonic cleaning of the glass cover will usually leave some invisible organic matter and particles, which will undoubtedly bury hidden dangers in the next process. The plasma cleaning machine can clean the glass cover more thoroughly. The main cleaning effect on the surface of the glass cover is activation, which can chemically react organic pollutants into hydrocarbons, generate carbon dioxide and water from the surface of the glass cover, and promote the next step. Etching, coating, bonding and other processes have greatly improved the product yield.

Plasma cleaning technology has the following advantages in processing:

(1) Environmental protection and energy saving. Compared with traditional wet cleaning technology, plasma cleaning technology makes dry process, does not consume water and chemical reagents, saves energy and has no pollution

(2) With online production capacity, fully automated processing can be realized, with short processing time, high efficiency and low cost

(3) Regardless of the type of substrate to be processed, it can be processed. It can process materials with more complex shapes and has good uniformity of surface treatment.

(4) The effect on the surface of the material only involves nano-level processing, which can give it another new function while maintaining the original special effects of the processed material.

(5) The processing temperature is low and does not cause damage to the surface of the material, especially suitable for processing polymer materials
