　　 Welding (bonding) machine
　　 Subsidiary machine
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.

Easy adjustment, common parameters are placed on the panel in the form of tuning button;
Automatic detect working height, the height of the first and second checking point can be adjusted respectively, can fit for the components that has large height difference in the first and second bonding positions;
Detail operation molds, suitable for beginner, skillful worker, or the situation of bad fixing, bad frame and etc. situations;
Chopper detecting function can detect if the chopper is installed properly, greatly reduce artificial rosin joint;
Provide 4 channels ultrasonic output, to fit for the different welding parameter requirement of wafer and bracket, make sure bonding consistency;
EFO technique, precise adjust balling size, good consistency. Adapting our special design chopper can get smaller first bonding (ball bonding) and more reliable second bonding, it is more suitable for the production of blue and white LED,
Automatic switch to weld the second point, and the three axes (welding head, moving, feeding) moving at the same time, faster bonding speed, suitable for the welding of blue and white tube;
When double direction welding, it will automatically switch to the first bonding position of the second wire after the first wire finished, it can improve efficiency and protect the first radian;
When double direction welding, the second checking height of the two wires can be adjusted respectively, suitable for the bracket welding of different two welding height;
Radian improvement function, there are many radian height solution available, use for bracket that has high demand to radian will improve the qualified rate greatly;
Two welding supply function can greatly improve the intensity of the two welding points, reduce dead center rate;
It can switch to single left-side automatic two weldings, provide convenience for operator who has got used to left-side automatic two welding;
For heating control of the clamp, it use PID system, ensure precision and stability;
Continuous feeding function, it can improve work efficiency of the rehandling bracket;
One step or two steps automatic feeding option, for Φ8 or bracket larger than ф10, choose two steps will greatly improve work efficiency;
Support clamp alarm function.; when every bracket weld to the 19th tube, the machine will buzz to remind the operator, and when change bracket and when finish welding the last tube, no need to take off the welding head, effectively saved operation time, and give certain preheating time for the first tube of the next bracket;
The wire welding speed is about 4-6K/H.

WL2202/2201 ultrasonic hot press gold wire ball bonding machine
The functions and performance of WT2202 is also most the same as those of WT2210, except that WT2202 has no 4 channels function (two channels). Detail functions is subject to the user’s manual.
The functions and performance of WT2202 is also most the same as those of WT2201, except that WT2201 has no displacement device (it can not automatically switch to the second welding point). Detail functions are subject to the user’s manual.
