Product name: SH2008-type gold ball wire bonders (b welding automatic)
Description: ultrasonic gold ball wire bonders
Usage
Gold wire bonders are mainly used in high power devices: light-emitting diode (LED), laser tube (laser), small and medium-power transistors, integrated circuits and semiconductor devices in some special wire welding.
Welding principle:
The use of ultrasound machines to achieve the principle of friction surface welding of different media, is a physical process of change. First gold for the formation of the first spherical end must be treated (with negative electron pressure of the machine into a ball), and the metal surface before welding the preheating; then gold ball at the time and pressure together, the metal welding deformation of the surface of moon, so that the two media to achieve a reliable contact and friction by ultrasonic vibration, the two atomic affinity between the metal atoms the formation of metallic bonds under the effect of realized gold wire welding. gold ball bonding and environmental applications in the electrical properties superior to Si-Al-wire welding, but welding pieces of precious metal must be heated, a relatively narrow range of applications .
Features:
1. With automatic welding and make the second ball joints function and three-axis (welding head, displacement, feed) to run simultaneously, greatly improving the wire speed;
2. Automatically through Step 1 or Step 2 of slice selection, the second solder ball can also be burned;
3. With two-way automatic arc welding and the displacement increased functionality. (Span of two-way displacement mode, in particular, can be welded for white, blue, and two-color LED production.)
4. Has a weld completed audible alert function, when each bracket 19 welded to the tube, there were audible prompts the timely replacement of stents.
5. Burning ball unsuccessful automatic alarm;
6. Wire speed, experts were up to 4-6K / H of the production (the general rate of automatic machine 8-12K / H);
7. Using titanium welding head, long life and stable performance.
8. Six operating modes can be different for beginners and skilled work status, and due to poor crystalline solid, frame and other factors adversely by the user choose different modes of operation to improve the quality of welding;
9. By a microcomputer control wire arc formation, arc can be adjusted;
10. With automatic program-controlled tip detection of whether the welding position to reach the function of adjusting a numerical check, second check the height of a weld, solder height difference between two large devices, welding also freely;
11. Easy to adjust various parameters (ultrasonic power, time, pressure, temperature, fire ball, arc, tail wire, aiming point height, span, etc.) are placed in the panel with a knob;
12. Temperature control has applied intelligent AI famous industrial control system, superior to the PID system, control more accurate, stable and reliable; main technical parameters
