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 first side to go through
The formation of spherical treatment (negative electron pressure this machine into a ball), and the welding of the metal surface before the preheating; then gold ball at the time
And pressure of working together, the metal welding deformation of the surface of moon, the two media to achieve a reliable contact and friction by ultrasonic vibration
Moving between the two metal atoms under the action of atomic affinity metal key, to achieve a gold wire welding. Gold ball bonding and the electrical properties
Environmental applications of welding wire is superior to alumina, but with the precious metal weldments must be heated up 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 speed wire
;
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 of the Second
Large difference between the devices, also welding freely;
11. Easy to adjust various parameters (ultrasonic power, time, pressure, temperature, fire ball, arc, tail wire, aiming point height, span, etc.
) Are placed on the panel with a knob;
12. Temperature control using brand-name industrial control system of intelligent AI, better than traditional PID system, control is more precise, stable and reliable; Main
