With the continuous improvement of the technical performance advantages of fiber laser cutting machine, laser cutting is gradually favored by more and more precision cutting industries, especially PCB high-precision laser cutting. The advantages of PCB laser engraving machines are small cutting gap, high precision, small heat affected area, etc. compared with the traditional PCB cutting process, PCB laser engraving machine is completely dust-free, stress-free, burr-free, and the cutting edge is smooth and neat. At present, in the field of high-precision machining, it is mainly high-precision laser cutting of flexible circuit board (PCB) and precision medical instruments. PCB is called a printed circuit board in Chinese, also known as the printed circuit board. It is an important electronic component, the support of electronic components, and the carrier of electrical connection of electronic components. With the development of intelligent electronic industry, PCB has more and more layers, smaller and thinner, more and more electronic components, and higher requirements for machining precision.
Advanced laser processing technology can be directly formed at a time, non-contact processing without burr, high precision, fast speed, especially the processing of PCB with components will not cause damage to components, becoming the best choice for many businesses. PCB proofing is an industry with high requirements for details in manufacturing and processing. It can't make any mistakes. The product requires high precision and stable performance. In PCB proofing, due to more and more strict customer requirements for sample size, physical size is also getting smaller and smaller, especially for the aluminum base plate, copper base plate, thick copper plate, which are relatively difficult to cut; Only by traditional manual machining, it is easy to cause large size error, uneven cutting, rough edge, and other conditions, especially those irregular shape cutting, it is even more difficult. Only laser cutting equipment with higher machining accuracy, faster-cutting speed, and smaller machining size can fully meet the needs.
The laser cutting machine is used for cutting the PCB metal plate. The whole cutting process can realize numerical control. It has the characteristics of non-contact, flexibility, automation, precision cutting and curve cutting, narrow cutting seam, high speed, and so on. The cutting torch has no contact with the plate, and there is no tool wear; the output parameters of the laser only need to be changed when processing parts of different shapes; the laser cutting process has low noise, small vibration, and no pollution. So laser cutting can get better cutting quality.
