Scope of application

Plasma cleaner cleaning machines are mainly used in the electronics industry for mobile phone case printing, coating, dispensing and other pre-processing, mobile phone screen surface treatment; connector surface cleaning; general industry screen printing, transfer printing pre-processing, etc.
There are two key reactions between the plasma of the atmospheric pressure plasma surface treatment machine and the surface of the substance. One is the chemical change caused by free radicals, and the other is the physical reaction caused by the plasma.
1. Chemical reaction:
The gases generally used for chemical reactions include hydrogen (H2), oxygen (O2), carbon tetrafluoride gas (CF4), etc. This gas reacts in the plasma of the atmospheric pressure plasma surface treatment machine as highly active free radicals, and interacts with The surface layer of the material reacts further. Its mechanism of action is mainly to use the free radicals in the plasma to produce chemical changes on the surface of the material. When the working pressure is very high, the free radicals are highly active and the movement is intense. Therefore, to make the chemical changes dominate, a lot of work needs to be manipulated. Only stress can develop a close response.
2. Physical reaction
Using the ions in the plasma as a purely physical impact, the plasma cleaner mainly knocks off the molecules on the surface of the chemical substance or the molecules on the surface of the chemical substance. Because the ions are at a low working pressure, their average free radicals are relatively light. It is long and has a certain accumulation of kinetic energy. Therefore, in a physical impact, the higher the kinetic energy of the ion, the more molecules it impacts. If you want to take the physical reaction as the leading factor, you need to carry out the reaction under a lower working pressure to make the actual cleaning The effect is stronger. The principle of the plasma cleaning machine is based on the "active effect" of the active particles in the plasma to achieve the goal of removing dirt. Plasma cleaning generally includes the following processes: agitating inorganic gas into a plasma state; absorption of gas-phase substances to the solid surface; reaction of absorption functional groups and solid surface molecules into product molecules; analysis of the product molecular structure into gas phase; reaction residues Get rid of the surface. The major feature of the plasma cleaner technology is that it does not need to distinguish the types of objects to be cleaned. For metal materials, semiconductor materials, metal oxides, and most fiber materials, such as polypropylene, polyester, polyimide film, and polyimide film, there is no need to distinguish between the types of objects to be cleaned. Ethylene chloride, epoxy resin, and even polytetrafluoroethylene, etc., can be processed to obtain corresponding effects, and can carry out overall, partial and complex structure cleaning.
The use of plasma cleaners in the electronics industry
Plasma cleaning machine, also called plasma surface treatment instrument, is a brand-new high-tech instrument. It uses the properties of active components to treat the surface of the sample to achieve the purpose of cleaning. In addition to cleaning, it can also activate and engrave. Corrosion, etc., are widely used in various fields. Let me give you an example: In the dry cleaning in the electronics industry, a vacuum pump is required to create a certain vacuum condition to meet the cleaning requirements. Let's take a look at the operation process and precautions of the plasma cleaning machine.
　　The plasma required for plasma cleaning is mainly generated by specific gas molecules in special occasions such as vacuum and electric discharge, like low-pressure gas glow plasma. Simply put, plasma cleaning needs to be carried out in a vacuum state (generally it needs to be kept at about 100Pa), so a vacuum pump is required for vacuuming.
The main process includes: first send the workpiece to be cleaned into the vacuum chamber to be fixed, start the vacuum pump and other devices to start vacuuming and exhaust to a vacuum of about 10Pa; then introduce the gas for plasma cleaning into the vacuum chamber (depending on the cleaning material, The selected gas is also different, such as oxygen, hydrogen, argon, nitrogen, etc.), and the pressure is maintained at about 100Pa; a high-frequency voltage is applied between the electrode in the vacuum chamber and the grounding device to cause the gas to be broken down and pass the glow The light discharge ionizes and generates plasma; after the plasma generated in the vacuum chamber completely covers the workpiece to be cleaned, the cleaning operation starts, and the cleaning process will last from tens of seconds to several minutes.
The following specifically introduces what to pay attention to when using the plasma cleaner. To
1. Before turning on the plasma cleaning machine, various preparations must be made. First, the operating staff must be trained in technical aspects, so that they can master the operating procedures and use them in strict accordance with the operating requirements. To
2. Before using the plasma cleaning machine formally, it is necessary to correctly set its operating parameters, and to perform the operation carefully in accordance with the instrument's instruction manual, and can not be used arbitrarily. To
3. Protect the plasma ignition device so as to ensure that the plasma cleaner can be turned on normally, otherwise it will cause difficulty in opening or abnormal opening. To
4. If the primary air duct is not ventilated, it is necessary to ensure that the operating time of the plasma generator is within the specified time and cannot be longer than the time required in the equipment manual, otherwise the burner will be destroyed, which will cause a lot of Unnecessary losses.
5. Regular maintenance and maintenance should be carried out. Maintaining and maintaining the plasma cleaner

At the time, the power of the equipment must be turned off first, and the corresponding operation can be performed after the power is cut off. It must not be operated with power to prevent accidents.
