Ultrasonic generator create ultrasonic (usually 40-140KHz), and produce high frequency librations through transducer, through amplitude rod and pass to chopper. When chopper touch with the down-lead and the welding object, in the force of pressure and librations, the welding metal surface scrub with each other, and the oxide film was destroyed, and occurred plastic distortion, and cause two clear metal surface touch closely, thus achieve the linking of atom distance, and finally form a firm metal bonding.
The down-lead material that ultrasonic welding used, in most cases, is aluminum wire and gold wire, copper also can be used for ultrasonic welding technique, at present, foreign countries have popularize copper welding in some range, our company will also dedicate in the researching of copper wire welding technology.

Large and medium power dynatron, field effect tube;
All kinds of power modules;
Large current large recover diode, Schottky audion, silicon controlled, IGBT.
IGBT;
The inner wire welding of above components and special semiconductor power components.
The moving of Y and Z directions of the welding head are driven by step motor which controlled by computer, transmitted by precise lead screw and track, flexible action, precise orientation and fast (for components on two wire, the speed is about 500-1300pcs/hour);
Large ultrasonic power margin volume, brand new designed transducer. It can maintain stable function in large power and long period. It has cleaver checking function, convenient to check if the cleaver is properly installed. Because transducer is the core of the machine, the stable function and the proper install of cleaver directly affect the weldability and the quality of the welding point;
The pressure is produced by electromagnetism, and adapts unique pressure automatic control technology. It is easy to adjust, and also stabilize pressure during welding, and maintain the precision, it plays very important role in ensuring the consistency of welding;
Outstanding ultrasonic, pressure and moving system, and matched with the cleaver that designed by us and produced by American company, these will make welding point firm, and obtain beautiful welding shape, good adjustability and consistency, it can completely matched with full automatic machine;
Has the first and second welding position double welding point function, in welding large area power component (i.e. audion, MOS tube, silicon controlled, power module), greatly reduce welding resistance, and improve reliability;
Can memorize the span, radian, aiming height and etc. data of two wires. It improve the operation speed of welding two wires power component (i.e. audion, MOS tube, silicon controlled, fast recovery Schottky diode);
Convenient adjust, all parameters (ultrasonic power, time, pressure, radian, span, height of aiming point, end wire) are placed on the panel, you may adjust by switches and tuning buttons;
Install all kinds of clamps of our company, it will fit for all kinds of sealing forms (for example: TO-3, TO-3P, TO-3PF, TO-3PN, TO-3PL, TO-220F, TO-126, TO-12F, TO-66, TO-251, TO-202 and etc.) semiconductor component production.
The excellent design of this machine has obtained many patents. It suitable for research institute, and the scientific research of college, it is also suitable for bulk production of semiconductor in Chinese situation, thus it become one of the best in the industry.
