LASER LIFT OFF TECHNOLOGY FOR MICRO LED
The display structure of the micro led is a miniaturized led array. At present, the size of a single micro led chip can be fewer than 10 μ m, which is 1% of the size of the conventional led. Each micro led can be regarded as a pixel, each pixel can achieve address control, separate drive and self-luminous. Structurally, micro led is a p-n junction contact diode that is formed by p-type GaN material and n-type GaN material while both the two materials are in close contact. When a forward voltage is applied on both sides of the p-n junction, that is, the positive voltage is applied on the p-type GaN side, and the negative voltage is applied on the n-type GaN side, the carriers on both sides of the p-n junction can easily move between each other. Then the radiative recombination of electron-holes occurs to produce light emission. The micro led array connects the positive and negative electrodes of each micro led through a vertical staggered positive and negative grid electrode and lights up the micro led to display the image by scanning through the sequence of the electrode lines.

A MOPA FIBER LASER MARKING TESTING ON PE MATERIAL
We used five main parameters to adjust the marking effect on the black plastic(PE) with MOPA fiber laser marker. They are “speed”, “frequency”, “power”, “fill distance” and “mode”. One of the advantage of our machine is that it has multiple mode(Pulse width)—8 in total, compared to other fiber laser source with only one mode. In this report, we test four parameters and marked the letter “A” on the material. To test, we change one specific parameter with 8 different values while keeping the other four parameters unchanged.

IC Automated Laser Soldering System
The IC automated laser soldering system is a fully automated custom assembly line. The IC components on the PCB board are soldered by laser soldering. The system transports the fixture in a pipelined manner, and the PCB is manually loaded onto the fixture. The fixtures are transported to various automatic operation stations through the assembly line, and the products are produced through automatic flux dispensing, automatic IC feeding, and automatic welding.
