Why is laser cutting machine the savior of PCB processing industry?
PCB is an indispensable and important part of 3C industry, as well as an important component carrier and line connection carrier. In this era of rapid development, efficiency has become particularly important. In industrial manufacturing, laser cutting machine has undoubtedly become a representative of efficient tools. China’s intelligent manufacturing has risen in the world. With the wide application of circuit boards, the demand for their processing is increasing, and the requirements for circuit boards are also getting higher and higher.
In the past, electronic equipment only needed a thick and heavy circuit board. Now, with the development of intelligent electronic industry, the number of PCB layers is increasing, smaller and thinner. In addition, FPC flexible circuit boards are also needed, so more and more electronic components need to be contained in the equipment, and the corresponding requirements for processing precision are also higher.
How can the circuit board industry adapt to this change and solve this problem?
As an advanced processing tool, laser processing has obvious advantages over traditional processing methods. With good monochromaticity, directivity, coherence and brightness, its energy and speed can be flexibly adjusted, and it can easily cooperate with the CNC system to achieve intelligent production. Therefore, laser processing has a very broad development space, and its penetration in automotive, consumer electronics, biomedicine and other fields is becoming stronger and stronger.
The advantages of laser cutting machine in cutting PCB are as follows:
1. Real cold working, basically no carbonization;
2. Ultra short pulse, energy release in picosecond time, small heat affected zone, negligible, no microcracks;
3. The speed is fast, the picosecond repetition rate is very high, and the galvanometer speed is fast;
4. The cutting effect is fine. Picosecond processing uses small single pulse energy. High frequency processing makes the processing surface more fine;
5. Wide range of processing materials, suitable for processing of various materials;
The laser cutting machine is almost dust-free, stress free and burr free when working, and the finished products can be said to be smooth and tidy. It meets the requirements of modern electronic equipment for circuit boards, and can also provide better operation opportunities for circuit boards, so that the circuit board industry can develop better.
For enterprises with high requirements for circuit boards, the use of laser cutting machines can bring rich returns, not only because of the improvement of the processing accuracy of circuit boards, but also because of the “fool” operation of circuit board laser cutting machines in terms of cost control, which does not require a lot of labor, and the efficiency does not decrease when the work is refined. Moreover, as a high-tech technology, artificial intelligence services guarantee the quality.
