Ultrasonic wire bonding machine generally refers to ultrasonic wire welding machine, which is a special method of connecting the same metal or different metal by using the mechanical vibration energy of ultrasonic frequency. When the metal is welded ultrasonically, neither current is transmitted to the workpiece, nor is a high-temperature heat source applied to the workpiece, but the vibration energy is converted into friction between the working rooms, so that the welding surface metal is limited in heating, plastic deformation is generated, and the oxide film and impurities in the welding area are eliminated in the initial stage of welding, and under the action of static pressure, the two metals are healthy together, that is, to achieve firm welding. Metal bonding between joints is a solid welding that is achieved without melting the material, so it effectively overcomes the phenomena of spatter and oxidation during welding. Ultrasonic wire welding machine can perform single-point welding and multi-point welding of filaments of non-ferrous metals such as gold, silver, copper, aluminum, nickel and so on. 　　Advantages of ultrasonic wire bonding machine 　　

1, high reliability: automatic wire welding machine is through adjustable digital time, pressure, power, temperature, arc and high CCD video capture, standard wire welding arc to ensure that each solder joint and arc to achieve welding effect. 　　

2, cost savings: effective saving of labor costs, one person can operate multiple machines, but also to avoid the use of manual wire welding machine when producing many defective products, resulting in material waste. 　

3, low energy consumption: the energy required by the automatic wire welding machine is equivalent to an ordinary manual wire welding machine. 　　

4, machine life: automatic wire welding machine is the use of high-quality imported accessories and finishing parts, with excellent wear resistance, easy to install, high welding accuracy, effective delay in machine life. 　　

5. The typical welding speed is several times that of the traditional manual wire welding machine. 　　

6, automation: small size, less maintenance workload, strong adaptability, so that the automatic wire bonding machine becomes the choice of LED automatic packaging production line. 　　

7. Good conductivity after welding, resistance coefficient or nearly zero. 　　

8. The requirements for welding metal surface are low, and oxidation or electroplating can be welded. 　　

9, short welding time, no need for any flux, gas, solder.
