Advantages of UV laser cutting on LED chips

The core LED chip is a solid semiconductor device. The heart of the LED is the semiconductor chip. One end of the chip is attached to the bracket, one end is the negative pole, and the other end is the positive pole connected to the power supply. The chip is encapsulated by epoxy resin.
 
Short-wavelength picosecond laser cutting machine can be used to scribing sapphire wafers, which effectively solves the difficulty of sapphire cutting and the requirements of the LED industry for small chips and narrow cutting paths, providing the possibility and guarantee of efficient cutting for the large-scale mass production of sapphire-based LEDs.
 
The core component of LED lamps, its main function is to convert electrical energy into light energy, and its main material is single crystal silicon. After the wafer is widely used as the substrate material in the production of LED chips, the traditional tool cutting can no longer meet the cutting requirements, so how to solve this problem?
 
The 355nm, 266nm and other short-wavelength nanosecond lasers of Lisse Laser can be used for wafer cutting, which effectively solves the difficulty of wafer cutting and the LED industry's requirements for smaller chips and narrower cutting paths, providing the possibility and guarantee of efficient cutting for large-scale mass production of wafer-based LEDs.

 
LaisaiAdvantages of laser die cutting machine:
 
1. Good cutting quality: Due to the small laser spot, high energy density and fast cutting speed, laser cutting can achieve better cutting quality.
2. High cutting efficiency: Due to the transmission characteristics of laser, laser cutting machine is generally equipped with multiple CNC workbenches, and the entire cutting process can be numerically controlled. The operation is simple, and it can be applied to cutting parts of different shapes by simply changing the computer graphics program. It can perform both two-dimensional cutting and three-dimensional cutting.
3. Fast cutting speed: During laser cutting, the material does not need to be clamped and fixed, which can not only save tooling and fixtures, but also save auxiliary time for loading and unloading materials.
Non-contact cutting: During laser cutting, the cutting torch does not contact the workpiece, and there is no tool wear. To process parts of different shapes, there is no need to change the tool, just change the laser output parameters. Adopt low noise, low vibration and pollution-free laser cutting process.
5. There are many kinds of cutting materials: For different materials, the adaptability of laser cutting varies due to their thermophysical properties and absorption rate. Show different laser cutting adaptability.
