Headlamp manufacturing plasma processing makes cold glue become the mainstream of the automotive industry
When BGA packaging process is carried out by plasma cleaning machine, almost all automobile headlamps are made of adhesive to meet the requirements of glue leakage between the light distribution mirror piece and the housing, hot melt adhesive and cold adhesive. They have their own characteristics. The characteristics of hot melt adhesive: in a fluid state at a certain melting temperature, by the active glue machine active glue injection, cooling speed is fast, glue production force occupies a greater advantage, so suitable for mass production. Cold adhesive characteristics: in normal temperature conditions in the fluid state, under the condition of the condensation, naturally over time, the coalition force will be more and more strong, the manual glue, suitable for small batch production, the sealing effect is better than hot melt adhesive, but under the condition of the need to stand for 24 hours after the condensation, need tooling and process, production cycle is longer than hot melt adhesive moment. It is assumed that the cold adhesive can obtain both cheap and high quality adhesive effect with reasonable technology and its own price advantage. The pretreatment of the cemented surface by plasma treatment makes this result possible, while the processing equipment of plasma treatment of the cemented surface is at atmospheric pressure, which makes this process acceptable to the user in terms of production and capital investment. Gaseous plasmas with different chemical properties produce different functional properties, such as surface materials that are more hydrophobic or more hydrophilic. Atmospheric plasma equipment does not require a valuable vacuum system, which makes the cost of the equipment and operating costs easily acceptable to the user, and because it is operated at atmospheric pressure, it can be well integrated with existing production lines for continuous production. As a result of these characteristics, some domestic automotive lamp manufacturing enterprises with considerable research and development strength have begun to explore or apply this production mode.

Study on graphene plasma etching of plasma cleaning machine manufacturers
Since 2004, there have been numerous research reports on graphene, including hundreds of related reports in Science and Nature. Research on graphene dates back to the 1970s. Clar et al. used chemical methods to synthesize a series of compounds with large conjugated systems, namely graphene sheets. Since then, Schmidt and other scientists have improved their method and synthesized many graphene derivatives with different edge modification groups, but this method cannot produce large planar graphene structures. In 2004, Geim et al. took graphite as raw material and obtained a series of new materials "graphene" called two-dimensional atomic crystals through micromechanical stripping method. Graphene, also known as a "single-layer graphite sheet," refers to a dense layer of carbon atoms wrapped around a lattice of honeycomb crystals, arranged in a two-dimensional structure similar to the single-atom layer of graphite. Geim et al. made use of nanoscale gold "scaffolding" to create a monolayer graphene film suspended on it. They found that the suspended graphene film was not a "two-dimensional flat structure", but a "microwave-like monolayer structure", and attributed the stability of graphene monolayer structure to its "nanoscale micro-distortion". Graphene is a zero-band gap material where electrons and holes can exist continuously, even at room temperature. Carrier concentration can be as high as 10-13cm3, and mobility can exceed 2000cm2 /V·s. The theoretical specific surface area of graphene is as high as 2600m2/g, and it has outstanding thermal conductivity (3000W/m·K) and mechanical properties (1060GPa). In addition, its special structure, so that it has half integer quantum Hall effect, never disappear conductivity and so on. Graphene can be used as both a channel material and a backend interconnection due to its excellent two-dimensional transmission properties and high electrical conductivity. Of course, different use of etching process requirements are also different. However, graphene faces two problems in chip manufacturing applications: one is how to continuously grow high quality films in large areas; The second is how to pattern. The second aspect is closely related to the etching process. In contrast, there has been a lot of research on large areas of growth, but not a lot of work on patterning. This is because it is difficult to grow large areas of graphene on its own, and even fewer have the ability to develop both. In general, there are several plasma etching methods for graphene, such as oxygen, hydrogen and argon. This in addition to oxygen and hydrogen plasma etching more. They take advantage of graphene's high activity to react with it, typically splitting large areas of layered graphene along 60° or 120°.The above is the CRF plasma cleaning machine manufacturers on graphene plasma etching research some introduction.

Plasma processing machine for plastic film to provide you with pretreatment solutions
Believe that you are no stranger to thin film materials, optical film, composite film, plastic film, metal film, superconductor film and so on, are more common membrane materials, and the thin film material is typically preprocessing, surface treatment of low temperature plasma processor, is a new kind of pretreatment method, through the processing of plasma processor, can be carried out on the thin film material surface cleaning, activation and coarsening, thus improve the film surface tension and adhesion, some friends to pretreatment the link still don't know, let's through plastic film packaging and printing industry is a typical example, To understand the necessity of film material pretreatment. The plastic film is light and transparent, oxygen-resistant and moisture-proof, smooth and folding resistant. It has advantages in performance and price, so it can often achieve good results in modern packaging and printing. But the plastic film is a non-polar polymer material with poor wetting, ink adhesion and color fastness. If the ink is directly bonded without pretreatment, it is easy to fall off and the printing effect is poor, which affects the printing and packaging effect. In addition, the pre-treatment can also improve the subsequent plastic film coating, composite, bronzing and other processing quality. Therefore, before printing, the thin film material must be treated by plasma processor or other pretreatment methods. Now that we have a certain understanding of the pretreatment of film materials, then the more common pretreatment of plastic film is chemical oxidation treatment, corona treatment and plasma cleaning treatment. The following to introduce the pretreatment of plastic film plasma processing machine processing. Plasma processor device surface treatment method is in the process of ionization, forming active particles in plasma, react with plastic film material surface, thus destroy the long chain molecules on the surface of the membrane material, form the high-energy group, in addition, the thin film material after being bombarded with particle physics, will form the rough surface, make the surface of the plastic film material freedom can be improved, as to enhance the surface dyne value performance. Plasma processing machine low temperature plasma surface treatment process is simple, easy to operate, clean and pollution-free, in line with environmental protection requirements, and safe and efficient treatment, no damage to the film material, suitable for mass production, production environment requirements are not high.
