Everyone knows that Mi Band has 3 LED indicators, which can display blue, green, red and orange, but how does this light show through?
The answer is laser drilling technology. Laser drilling uses a high-power density laser beam to irradiate the processed material, so that the material is quickly heated to vaporization temperature, and evaporates to form holes. It has high efficiency, good drilling quality, and good roundness. It is especially suitable for processing fine and deep holes. Using laser drilling technology, a micro-hole with a diameter of about 35um is machined on the aluminum alloy surface of the Xiaomi bracelet. The diameter of the hair is 40um-200um, which is thinner than the hair, and the light will come through the hole.

Not only bracelets. In recent years, with the vigorous development of the 3C industry, the frequency of product upgrades has been accelerating, which also puts forward higher requirements on the production process of electronic products. Laser drilling is one of the important 3C processing application technologies.
Laser drilling can be used in mobile phones, notebooks, PCB boards, headphones and other electronic products in mobile phone applications. Using traditional CNC processing technology, the surface of the material is easy to bulge, and there are many burrs on the edge of the hole. Laser drilling can avoid such problems.
All you need to do is set up the graphics that need to be punched in the computer program, a beam of light flashes, and in the blink of an eye, the high-quality, well-rounded micro-holes are successfully completed. The micro-holes on similar bracelets are processing precision that CNC can not achieve, and the use of laser processing has obvious advantages.
