The difference between corona treatment and plasma cleaning machine treatment

The difference between corona treatment and plasma cleaning machine treatment

Corona treatment is a click treatment method, it can make the substrate surface has a high bond strength. Because most of the plastic film nonpolar polymer, low interfacial tension, not a fixed printing ink and adhesive, so should choose corona discharge method to deal with this kind of surface layer of plastic film, discharge of reactive oxygen species is a kind of strong oxidation, it can change the molecular structure of the plastic film, make its formation in air oxidation carbonyl, peroxide and other groups, to improve the surface performance.   Plasma cleaning machine surface treatment is based on high energy particles and organic material surface layer produced by physical or chemical change, can be used to solve the raw material surface activity, etching process, the problem such as decontamination, unlike corona treatment, corona discharge treatment can only solve very frivolous products, such as plastic film products, such as the material specifications can't be too big in the process of production.   The common points of surface treatment and corona treatment of plasma cleaning machine are: 1. High frequency and high voltage discharge is adopted for plasma equipment and electric airsickness treatment. Plasma is selected to modify the surface of materials. 2. Both methods can improve the surface adhesion of raw materials and are conducive to the adhesion, painting and printing of materials. 3. All are online production processing, production and manufacturing.   Differences between plasma treatment and corona surface treatment: 1. Plasma cleaning machine surface treatment in addition to glow discharge, also contains electric volt charge and discharge, can generate a lot of kinetic energy, to reach the adhesive force of 50 or more, and electric motion sickness generally can only reach the adhesive force of about 30 degrees. 2. Corona discharge has a wide range of action, suitable for products with low bonding strength requirements, such as cloth, plastic film, plastic and so on. The plasma surface treatment area is relatively narrow, sometimes several nozzles need to cooperate to complete the total width treatment, the production cost is higher, but the effect is better than corona.

Brief Introduction of ultra-low temperature plasma etching technology for surface treatment of plasma Cleaning Machine

Brief Introduction of ultra-low temperature plasma etching technology for surface treatment of plasma Cleaning Machine

Plasma etching is defined as the plasma etching process that takes place at -100℃ or below, with liquid nitrogen or liquid helium as the cooling source and sulfur hexafluoride gas and oxygen (SF6/O2) as the etching source.   The low temperature etching method of plasma cleaning machine surface processor originates from the requirement of large aspect ratio silicon structure etching and is mainly used to form the structure of silicon material with maximum aspect ratio. This structure is widely used in micro-electro-mechanical System (MEMS) front process and Through Silicon Vias (TSV) encapsulated in the rear segment.   In recent years, the study found that the Plasma cleaning machine processor on the surface of Low temperature Plasma etching structure can not only needed for the formation of a special material, at the same time can also be produced in the process of etching reduce Plasma Damage (Plasma Induced Damage, PID), which can reduce accordingly after a period of semiconductor etching process of Low dielectric constant (Low - k Damage) material injury.

Basic principle and application of plasma plasma cleaning machine surface treatment and degumming

Basic principle and application of plasma plasma cleaning machine surface treatment and degumming

1) Gel removal reaction principle: Oxygen is the main component of corrosive gases in dry rubber removal. Plasma plasma cleaning machine surface treatment of gel with high frequency and microwave energy weak electrolyte, so that oxygen ions, free oxygen molecules O, oxygen atoms and electron mixture in high frequency working voltage and lithography film reaction: O2→O*+O*, CxHy+O*→CO2↑+H2O↑, after the reaction is completed, remove CO2 and H2O.   2) Plasma plasma technology for gum removal: Take vacuum plasma cleaning machine as an example. The material to remove adhesive was placed in the vacuum system and inserted between two electrodes, and the high-voltage output power was increased under the sound chamber working pressure of 1.3-13PA. Glow charging and discharging was performed in the middle of the electrode. By adjusting the performance parameters such as output power and total flow rate, different speed of removing adhesive could be obtained.   Influence of plasma-cleaning machine surface treatment on removing glue: Frequency selection: the higher the frequency, the easier it is for oxygen ionization to produce plasma, the amplitude of electrons is less than the average category, the probability of collision between electrons and gas molecular structure is reduced, so that the weak electric solution speed is reduced. Frequency selection is usually 13.56MHz and 2.45GHz. Efficacy output: For a certain amount of gas, the output power is large, the density of active particles is large, and the degumming speed is fast. However, when the output power is increased to a certain value, the energy-consuming active ions reach saturation, and the degumming speed is not obvious when the output power is increased. The size of the power needs to be adjusted according to the actual application standard. Selection of vacuum value: the moderate increase of vacuum value can increase the average free motion of electrons and increase the kinetic energy obtained from electrostatic field, which is beneficial to the weak electrolyte. When oxygen fluidity is maintained, the higher the vacuum value, the greater the relative share of oxygen and the greater the concentration of specific particles. If the vacuum degree is too high, the concentration of the active particle will decrease. The influence of oxygen flow rate on the surface treatment of plasma plasma cleaning machine: high oxygen flow rate, high density of activated particles, fast degumming speed, but too fast, increase the probability of positive ion synthesis, reduce the average free path of electrons, reduce the compressive strength of the weak electrolyte. Assuming that the working pressure of the reflecting chamber is stable and the total flow rate rises, the gas extraction rate will also rise, and the pumping rate of the active particles not involved in the reaction will also rise, so the flow rate has no obvious effect on the degumming effect.

Failure time of plasma surface treatment

Failure time of plasma surface treatment

Plasma surface treatment machine processing materials, surface failure time depends on the treatment of which kind of materials, different materials after processing can meet the relevant bonding function. Cleaning generally involves several links on the reaction mechanism: inorganic gas is fully mobilized into the plasma state, the gas adheres to the solid surface, and the adhesion group reacts with the solid surface to form the molecular structure of products; The molecular structure of the product is dissolved and the residue is shed after the reaction.   It can be measured with a Dyne pen and an antenna tester. Through repeated tests on different materials, it is found that the service life of some metal products is long and will fail after one or two days, while the service life of plexiglass and plastic board is short and even fails within a few minutes. Therefore, the next stage of processing should be carried out according to the aging effect of plasma equipment after processing the material surface.   After treatment, components or components cannot be stored outdoors because they absorb dust, organic air pollutants, and water. Shrink-wrapped products, for example, have a longer shelf life than products stored outdoors. In general, users are advised to proceed to the next step immediately after obtaining good surface energy from plasma surface processing to prevent the adverse effects of reduced surface energy.   The failure time of plasma surface treatment is mainly affected by gas type, process parameters, chemical composition, molecular structure and storage environment of materials. Therefore, in the specific processing material surface to be treated with equipment, surface to ensure that clean, storage temperature should not be too high, at the same time, timely completion of packaging, printing, spraying or bonding procedures, to prevent the debilitating effect of processing and surface adaptability reduced.
