Brief description:

Application of vacuum plasma cleaning machine PCB industry: Clocking effect on material surface - Physical effect: A large number of ions, excited molecules, free radicals and other active particles in the plasma act on the surface of solid samples, not only removing the original pollutants and impurities on the surface, but also producing etching effect, which will cause damage to the surface of the sample

The application of plasma cleaning has been very, very extensive, in automotive manufacturing, mobile phone manufacturing, glass optics, materials science, electronic circuits, printing and papermaking, plastic film, packaging technology, medical and pharmaceutical, textile industry, new energy technology, aerospace and military industry, watches and jewelry, and so on.

Application of vacuum plasma cleaning machineWhat are the application cases of vacuum plasma cleaning machines in the PCB industry? Plasma is the fourth state of matter that is not mysterious!

There are solid, liquid, and gaseous substances in nature that we are very familiar with. Continuously providing energy to matter, the temperature of matter will rise, and the state of matter will also changeSolid liquid state, liquid gas state, gas plasma state.

Matter is composed of atoms, which consist of positively charged nuclei and negatively charged electrons surrounding the nuclei. When energy is continuously supplied and heated to a sufficiently high temperature, the beam of electron modes detached from the nucleus of the outer chamber becomes a free electronThis process is called 'ionization'; Commercial matter is composed of positively charged atomic nuclei and charged electrons. Of course, a single commercial substance is

There are also active groups and excited state nuclides(metastable state), photons, etc. are a uniform "paste", so plasma is also called plasma. In plasma, the total amount of positive and negative charges is equal, so it is generally electrically neutral and called plasma.

Plasma is a high-energy unstable state. By utilizing this high-energy and unstable state, plasma has various applications.

in the universe99% of the available materials are actually in the state of falling bodies, such as flashes, auroras, nebulae, and other celestial bodies, as well as the bioluminescent and icy iridescent light in our daily lives, which are also ionized bodies.

Build a leading brand in the surface performance industry with the spirit of craftsmanship

(2) Application of direct plasma cleaning machine in PCB industry 21: Etching effect on material surface - Physical effect:

A large number of ions, excited molecules, free radicals and other active particles in the plasma act on the surface of solid samples, not only removing the original pollutants and impurities on the surface, but also generating etching effects, roughening the surface of the sample, forming many fine pits, and increasing the specific surface area of the sample. Improve the wetting performance of solid surfaces.

2.2 Activation bond energy and cross-linking effect

The energy of particles in plasma0~20eV， And most of the bond energies in polymers are between 0 and 10V, so when plasma acts on the surface of the solid, it can break the original chemical bonds on the solid surface. The free radicals in the plasma form a network like cross-linked structure with these bonds, greatly activating surface activity.

2.3 Formation of new functional groups - chemical reactions

If reactive gases are introduced into the discharge gas, complex chemical reactions will occur on the surface of the activated material, introducing new functional groups such as alkyl, amino, carboxyl, etc. These functional groups are all active and can significantly improve the surface activity of the material.

0.6KW input voltage: 220/230VAC ± 10% 50/60KHz working frequency: 225KHz power control: two-stage inverter, 190-250V wide range voltage regulation, output power can be prefabricated and adjusted. Number of nozzles: 1 (quantity can be customized) External nest size: 38mm Air source: 0.4-0.6bar Working pressure is automatically stabilized by PID control. Control system: PLC human-machine interface automatic control, can achieve automatic matching of speed and plasma power, with low-speed and paperless shutdown

(3) What are the structural components of a plasma cleaning machine?

The structure of a plasma cleaning machine is mainly composed of two parts:

One is the plasma generator, which consists of integrated circuits, operation control, plasma generation power supply, gas source processing, safety protection, etc. One is the plasma treatment device, which consists of excitation electrodes, excitation gas paths, etc.

(4) Technical advantages:

The Xia Kong plasma processing machine can process folded gold cardboard boxes and the adhesive parts of cardboard boxes(including film room, light window original, gold and silver cardboard, sales paper, etc.), the surface tension after external treatment reaches 70 dynes or more per day, thereby enhancing the firmness of the paste box, allowing you to get rid of the trouble of glue opening, improving the quality of the paste box, and reducing the risk of product defects.

Can replace hot melt adhesive with cold glue or low-grade ordinary adhesive, and reduce the amount of glue used, effectively reducing production costs;

By using plasma processing technology, it is possible toUV coating, PP film coating and other difficult to bond materials can be firmly bonded with water-based adhesives, and eliminate processes such as mechanical punching, punching, and chemical primer coating, which do not produce gray cattle or waste eyebrows. This meets the hygiene and safety requirements of packaging for drugs, food and other products, and is conducive to environmental protection

The high-speed processing machine does not require a vacuum environment and can be processed online. It can be connected to the laminating machine production line to achieve automatic operation and improve production efficiency High speed sub processor technology

It will not leave any pain on the surface of the paper box, and will also reduce the generation of bubbles.

(5) Atmospheric Rotating Plasma Front

The application of plasma is very, very extensive, from nuclear fusion to plasma television, from plasma film laser to industrial room gas treatment, from plasma cutting and blasting to the field of biomedicine

disinfect

What we are currently talking about is focused on the application of plasma surface modification or plasma surface treatment. It is to utilize the high-energy and unstable characteristics of plasma when solid

After the material surface comes into contact with plasma, the microstructure, chemical properties, and energy of the surface will undergo crosslinking.

Plasma Shoushang Modified Parts(Waiting for the birthday noodles to be treated) is the use of the special properties of the waiting body to clean, activate, and activate the surface of solid materials that need to be treated, in order to firmly fix them?

The purpose of surface microstructure, chemical properties, and energy.

Here are some typical applications:

1. Mobile phone cover

In the production of mobile phone covers, multiple layers of coating are required. Before coating, plasma cleaning is needed to ensure high adhesion and good coating effect, thereby improving the surface activity of the cover and extending the coating life. The current industry standard requires that the contact angle measurement angle after cleaning be lower than20 °.

2. Plastic printing

The common plastic bottle cap printing in daily life, in the assembly line production process, if the cap is directly printed, the oil adhesion effect will be relatively poor, and the product rate will be high.

Before printing the bottle cap, plasma cleaning is used, which not only can*It is integrated into the production line and printed after bottle cap cleaning, resulting in significantly improved finished text, better ink adhesion, and longer lasting effects.

3. Radar sensors

In the production process of Yingda sensors, cleaning is necessary because the sensor surface requires a very clean surface to ensure the accuracy and stability of the sensor. The traditional method uses manual alcohol wiping, which has poor cleaning effect, instability, and high cleaning efficiency,Focused on providing surface performance treatment and testing solutions for our customers!
