Thick Wire Bonding Machine Ultrasonic thick aluminum wire welding machine

Equipment features:

1. The Y and Z direction movement of the welding head is driven by a computer-controlled stepper motor, precision screw and navigation transmission, flexible movement, accurate positioning and fast speed (about 500-1300 tubes per hour for two-line devices);
2. The ultrasonic power surplus is large, and the new transducer design is stable and reliable under high power and long-term conditions. It is also equipped with a splitter installation detection function to facilitate the judgment of whether the splitter is correctly installed. Because the transducer is the core component of this machine, its stable operation and the correct installation of the splitter directly affect the weldability and the quality of the solder joint.
3. The pressure is generated by electromagnetics, and the original pressure automatic control technology is adopted. It is not only easy to adjust, but also stable and accurate in the entire welding process, which plays an important role in ensuring the consistency of the solder joint.
4. The excellent performance of the ultrasonic, pressure and motion system, combined with the splitter designed by our company and manufactured by the American company, makes the solder joint firm, the solder joint shape and the arc shape beautiful, adjustable and consistent, which is completely comparable to the automatic machine.
5. It is equipped with one-weld and two-weld double soldering point functions. When welding power devices with large chip areas (such as thyristors, power modules, etc.), the soldering point resistance is greatly reduced and the reliability is improved.
6. It can memorize the span, arc, aiming point height and other data of two lines, and improve the operation speed when welding power devices of two lines (such as transistors, MOS tubes, thyristors, fast recovery and Schottky diodes).
7. It is easy to adjust. Various parameters (ultrasonic power, time, pressure, arc, span, aiming point height, tail wire, etc.) are placed on the panel and adjusted by switches and knobs.
8. It can be configured with a variety of fixtures to adapt to the production of semiconductor devices with various packaging forms (such as TO-3, TO-3P, TO-3PF, TO-3PN, TO-3PL, TO-220, TO-220F, TO-126, TO-66, TO-251, TO-202, etc.).
9. The thick wire bonding machine can also weld aluminum strips, gold strips, copper wires and other metal wires.
