ASM wire bonding machine mostly uses ASM copper wire welding, which overcomes the phenomenon of spatter and oxidation during welding. It has the ability of macro wire bonding and specializes in processing advanced packaging products. So what is the working principle of ASM wire bonding machine welding?

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 needs to 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 needs to 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.

The above is the working principle of ASM wire bonding machine welding. The traditional manual welding method has been more and more unable to meet the requirements of the production process. Therefore, the use of ASM wire bonding machine for welding can be said to be a good choice.
