Views：1472The industrial processes of sheet metal are cutting, welding, drilling normally, among these processes, drilling is kind of complicated and it has higher requirement for the equipment.
The traditional processes have stamping, drill head and so on. With the improvement of technology, laser drilling is getting popular. Laser drilling has many advantages like laser can drill nearly any thick plates, the speed is way faster then the normal drilling process. The both sides after drilling are smooth, the operator is able to use computer to draw any shape of holes.
Laser drilling is an early practical laser processing technology as well as one of the main industry of laser application. Those materials that with high hardness and high melting point, the traditional way cannot solve and meet the technical requirements. The mechanical process is very difficult to process the holes even it is an impossible task sometimes, however, laser can easily achieve the target.
The laser beam is highly concentrated in space and time, and by focusing with a lens, the diameter of the spot can be reduced to the micrometer level to obtain laser power density. Such high power density can be used for laser drilling in almost any material. Compared with other conventional drilling methods such as mechanical drilling and Electrical discharge machining, laser drilling has the following significant advantages: fast drilling speed, high efficiency and good economic benefits.
With the increasing demand for high-precision processing, related precision processing technologies have also developed rapidly, among which laser precision drilling technology has gained more and more recognition in the market. At present, laser precision drilling is the most widely used in the PCB industry. Compared with traditional PCB drilling processes, laser not only has a fast processing speed on PCBs, but also can achieve 2 μm Drilling of small holes, micro-holes, and invisible holes. On the surface of electronic products, it can also be used for drilling holes on phone speakers, microphones, and other glass.
