Plasma equipment plays a big role in the electronic product bonding and assembly industry

Plasma equipment plays a very important role in the bonding and assembly industry of electronic products. Let’s take a mobile phone as an example to talk about the advantages and disadvantages of plastic spraying: Everyone knows that phones like piano lacquer or mirror are too easy to get dirty. Although they are beautiful, they require too much energy to take care of. The plastic spraying process just solves this situation. The mobile phone using this technology not only looks very textured, but also has a good non-fingerprint and non-slip feel. Simply put, the plastic spraying process is to spray a layer of special paint on the surface of the shell. After it dries, it can achieve the functions of stain resistance and anti-fingerprints. However, the adhesion ability will decay over time. While the plastic spraying process brings excellent texture, it also improves the quality of mobile phones. However, the plastic spraying process is not perfect. After many mobile phones are used for a period of time, the phenomenon of "peeling" often occurs, that is, the plastic will fall off in one piece, which seriously affects the appearance of the mobile phone. Then the use of plasma equipment can completely solve the problem. In this case, Guoxing Technology will tell you about the three aspects of plasma treatment. Plasma equipment plays a very important role in the electronic product bonding and assembly industry, and each role has a specific purpose: First: clean; Second: activation; Third: Etching; While we are using plasma to process the workpiece, all three effects are taking place, so which one we need most and which one is the most important is what we need to consider; First: clean; It is possible that the surface of some workpieces is originally dirty, such as the release agent on the surface of the injection molded part, the residual glue on the surface of the glass, etc. Sometimes the release agent cannot be observed with the naked eye, but it does exist. Then we need to perform plasma treatment to remove the contaminants. Clear away, so that the surface of the workpiece is itself, which is cleaning; there are two ways to clean: one is a chemical reaction, such as a polymer compound of CHO, we use oxygen plasma, O+C=CO+CO2, O+2H=H2O and other materials that react to produce meteorology are taken away by the vacuum pump. The second is physical impact. The particles have a certain kinetic energy and energy under the control of electric field force, which tells the impact of the surface of the workpiece, some small particles may be It is cleared; but the particles are so small that we can't imagine, so he can only hit things smaller than him, so they are all meteorological things and will not cause damage to the surface of the workpiece; Second: activation; The main principle of activation is mentioned above, so every glue system and coating coating has its favorite groups. For example, the acrylic glue system in the glue has carboxyl groups, which have an affinity for carboxyl groups. We have two kinds of coatings: A and B. A prefers hydroxyl groups, so we put the surface of the object through plasma treatment to allow the hydroxyl groups to exist on the surface of the workpiece. At this time, when we coat the material A on the surface of the workpiece, the bonding force is very good; if We coat the processed workpiece with B paint at the same time, it may not be effective and easy to fall off; so the concept of activation is to introduce corresponding functional groups, groups, chemical bonds (such as positive or negative charges), etc., Therefore, in addition to our treatment process, there are also coating materials related; for example, when some workpieces are recoated, the effect of our treatment with oxygen is good, but the effect of treatment with argon is not good. This is the principle; Third: etchback; When two objects are in contact, they have a surface area, and the distance between the two points is the closest in a straight line. When two objects are in contact, if both are smooth, then the contact surface is the smallest. If the two objects are very rough, a mountain topography is formed. , Then when these two objects are in close contact, their contact surface will be greatly enlarged, so our etchback is based on this principle. For example, we sometimes have a process of roughening before bonding and coating. , That's it, but our plasma surface treatment is to make the amount of etchback to be the smallest. Its morphology is molecular-level etchback, which cannot be observed with the naked eye, so we can't see whether the surface of the workpiece is damaged. If you perform SEM Scanning with an electron microscope, you can see their processing effect; Plasma equipment plays a very important role in the electronic product bonding and assembly industry. Guoxing Technology has a complete set of customer systems. For after-sales: 1. Establish customer files and provide relevant technical training and technical materials according to customer requirements . 2.
