The overall solution for plasma surface treatment of Guoxing Technology in Jiangdu District of Yangzhou is explained in detail as follows: First, let's first understand the basic overview of plasma. The use of an external electric field or high-frequency induction electric field to make gas conduction is called gas discharge. Gas discharge is one of the important means to generate plasma. The electrons in the partially ionized gas accelerated by the applied electric field collide with neutral molecules, and the energy obtained from the electric field is transferred to the gas. Elastic collisions between electrons and neutral molecules lead to an increase in molecular kinetic energy, which is manifested as an increase in temperature; inelastic collisions lead to excitation (the electrons in molecules or atoms transition from low energy levels to high energy levels), dissociation (molecules decompose into atoms) or Ionization (the outer electrons of molecules or atoms change from bound state to free electrons). High-temperature gas transfers energy to the surrounding environment through conduction, convection and radiation. Under steady conditions, the input energy and loss energy in a given volume are equal. The rate of energy transfer between electrons and heavy particles (ions, molecules, and atoms) is proportional to the collision frequency (the number of collisions per unit time). Second, what is the principle of plasma treatment? Plasma is an existence state of matter. Generally, matter exists in three states: solid, liquid, and gas, but in some special cases, there is a fourth state, such as the substance in the ionosphere in the earth's atmosphere.

Third, the following substances exist in the plasma state: electrons in a state of high-speed motion; neutral atoms, molecules, and atomic groups (radicals) in an activated state; ionized atoms and molecules; unreacted molecules, atoms, etc., but The substance remains electrically neutral as a whole. Fourth, plasma processing technology is a specific application of the special properties of plasma: the plasma processing system generates plasma by setting two electrodes in a sealed container to form an electric field, and a vacuum pump is used to achieve a certain degree of vacuum. As the gas becomes thinner and thinner , The distance between molecules and the free movement distance of molecules or ions is getting longer and longer. Under the action of electric field, they collide to form plasma. These ions are very active and their energy is enough to destroy almost all chemical bonds on any exposed surface. Causes chemical reactions. Plasma of different gases has different chemical properties. For example, plasma of oxygen has high oxidizing property and can oxidize photoresist to react to generate gas, so as to achieve the effect of cleaning; plasma of corrosive gas has very high oxidizing property. Good anisotropy, so that it can meet the needs of etching.

Fifth, there are several names for plasma cleaners, called (Plasma Cleaner) in English, also known as plasma cleaner, plasma cleaner, plasma cleaner, plasma etching machine, plasma surface treatment machine, plasma cleaner, plasma cleaner , Plasma to glue machine, plasma cleaning equipment. Plasma cleaning machine/plasma treatment machine/plasma treatment equipment is widely used in plasma cleaning, plasma etching, plasma coating, plasma ashing, plasma treatment and plasma surface treatment and other occasions. Through its plasma surface treatment, the wetting ability of the surface of the material can be improved, so that a variety of materials can be coated, coated and other operations, enhance the adhesion, bonding force, and remove organic pollutants, oil or grease at the same time. Sixth, the composition of the plasma surface treatment device of this scheme: the plasma surface treatment device is composed of a reaction chamber (also called a vacuum chamber), a vacuum system, a plasma generation system, an electronic control system, and an intake air flow control system. Considering the simplicity and efficiency of the production operation, the margin savings of the processed material and the cost-effectiveness of the processing device, the device is planned to adopt a horizontal placement structure. The reaction chamber is composed of a vacuum chamber and a plate electrode. It is an effective space for plasma (Plasma) processing reaction. The items to be processed are placed horizontally in the reaction chamber and can be designed as a multi-layer structure to facilitate mass operations; the vacuum system consists of vacuum valves, The vacuum pump, vacuum piping, vacuum system control actuators, etc. are responsible for pumping the air in the reaction chamber to a pre-set value and maintaining the corresponding vacuum degree during work; considering that the processed materials of this device require cleaning and activation, Therefore, the plasma generating source of this device is planned to adopt a plasma generating source with a specially processed waveform and a high-speed oscillation function. The system source provides plasma energy to the reaction chamber to excite the reacted gas in the reaction chamber to oscillate and ionize rapidly. Form the required plasma (Plasma) with cleaning ability; the function of the electronic control system is to intelligently and optimally automatically control the whole process of the device's process flow according to the preset process parameters and steps, and can self-tune and maintain the process parameters The stability of the process reaction gas inlet flow control system is mainly composed of a mass flow meter and a self-control electromagnetic valve. Its function is to accurately control the inlet flow rate of the reaction gas and maintain the required vacuum value during work.
