Applications for laser drilling

【Description】:

Laser head punching has gradually become popular. The laser head can punch almost any thickness of the plate. The punching speed is hundreds of times that of drilling. The cutting surface is smooth on both sides, and any shape can be drawn by computer for punching.

The laser beam is highly concentrated in space and time. Using a lens to focus, the spot diameter can be reduced to the micron level to obtain a laser power density of 105-1015 W/cm2.


Applications for laser drilling

Laser drilling is fast, efficient and economical. Since laser drilling uses a high-energy laser beam with a power density of 107-109 W/cm2 to act on the material instantaneously, the action time is only 10-3 ~ 10-5 s, so the laser drilling speed is very fast. High-efficiency drilling can be achieved by combining high-efficiency lasers with high-precision machine tools and control systems, and through program control by microprocessors. Compared with EDM drilling and mechanical drilling, the efficiency of laser drilling on different workpieces is increased by 10-1000 times.


Applications for laser drilling

At present, laser precision drilling is the most widely used in the PCB industry. Compared with the traditional PCB drilling process, the laser not only has a faster processing speed on the PCB, but also can realize small holes, micro holes and invisible holes below 2μm that cannot be achieved by traditional equipment. Drilling of holes. On the surface of electronic products, it can also be used for drilling holes on mobile phone speakers, microphones and other glass.
