A big advantage of the application of ASM bonding machine technology is that it can create a brighter paint effect. The actual effect of some electrostatic powder metal materials has been close to or exceeds that of liquid architectural coatings. The processing technology also enables everyone to better use a variety of color pastes.

1. The electrostatic powder of the ASM wire bonding machine has less damage, and it is easy to obtain a symmetrical color of the metal material.

2. The utilization rate of powder form is close to 99.99%, which is the same as general powder form; it can be extended to the bonding of composite powders, arts and crafts powders, etc. plus dyes and modifiers.

3. When using electrostatic induction gun to spray paint, it is not easy to accumulate and block the problem of metal color paste;

4. If the measurement verification is accurate, the reliability of the batch number will be very good; the metal material color paste is not easy to fly and gather in the production workshop, which improves the application safety factor.

5. Wide selection of metal material color paste. Bonding of color pastes for aluminum, copper, zinc, stainless steel, matt and other metal materials;

6. The problem that the color paste of metal materials and the base powder are not separated; the erasability of the color paste of metal materials is solved;

7. Because the ratio between the metallic material color paste and the powdery particles is relatively fixed, it can be completely used again to purchase the powdery form, and the new user and the purchased powder can achieve basically the same color tone;

8. It can improve the difficulty of poor induction electrification of metal material color paste, and increase the powdering rate of electrostatic powder.

9. ASM wire bonding machine can improve the actual effect of the dispersion of metal color paste and the color cast problem caused by the difference in particle size distribution. 10. It can reduce the amount of expensive metal material color paste and reduce the cost of metal material electrostatic powder.

With the acceleration of the replacement of electronic components and the development of electronic development in the direction of miniaturization and miniaturization, more and more traditional manual welding methods have been unable to meet the requirements of the production process. Therefore, the use of ASM wire bonding machines for welding is An inevitable choice in the future. For manual machine welding, it is still an adaptive process. Therefore, in order to ensure the quality of welding products, we must analyze its principles. Only in this way can we ensure the normal operation of automatic welding and control of product quality.

The welding principle of ASM wire bonding machine:

Automatic soldering is a university question. Its principle is to heat and melt the solid solder wire through an automatically heated soldering iron. At the same time, with the help of the flux, it flows into the metal to be welded, and forms a firm and reliable soldering after cooling. point. This process is done by the machine itself, we only need to control the machine manually. When the solder is a tin-lead alloy and the soldering surface is copper, the solder first wets the soldering surface. With the occurrence of the wetting phenomenon, the solder gradually diffuses into the metal copper, forming an adhesion layer on the contact surface of the solder and the metal copper, so that the two It is firmly combined. Therefore, it can be said that the ASM wire bonding machine is completed by the three physical and chemical processes of wetting, diffusion and metallurgical combination.

1. Wetting principle: The wetting process means that the melted solder (tin wire) uses capillary force to flow along the fine unevenness and crystal gaps on the surface of the base metal to form an adhesion layer on the surface of the base metal to be welded. , So that the solder and the atoms of the base metal are close to each other, reaching the distance where the atomic attraction works. Environmental conditions that cause wetting: The surface of the base metal to be welded must be clean and free of oxides or contaminants. An image metaphor to make an image is: water drops on the lotus leaf to form water droplets, that is, water cannot wet the lotus. When water drops on the cotton, the water penetrates into the cotton, which means that the water can wet the cotton.

2. Diffusion principle: With the progress of wetting, the inter-diffusion phenomenon between the solder and the metal atoms of the base metal begins to occur. Usually atoms are in a state of thermal vibration in the lattice lattice, once the temperature rises. The intensified atomic activity causes the atoms in the molten solder and the base metal to cross the contact surface into each other's lattice lattice. The moving speed and number of atoms are determined by the heating temperature and time. This we can clearly see during the welding process, which is the phenomenon that the tin wire flows out after melting.

3. The principle of metallurgical bonding: due to the mutual diffusion of the solder and the base metal, an intermediate layer is formed between the two metals-a metal compound. To obtain a good solder joint, a metal compound must be formed between the base metal and the solder. , So that the base material achieves a strong metallurgical bonding state. This is like steelmaking, where multiple metals are melted and joined together. Therefore, it can be said that we only have a deep understanding of these principles before we can use the ASM wire bonding machine robot to perform good welding. After all, the ASM wire bonding machine robot is also developed by imitating the manual welding principle.
