PCB is called the printed circuit board and is an important device in the electronics industry. As an important carrier for connecting components, it supports the development of the electronics industry. Any electronic product is inseparable from the application of PCB circuit boards. With the huge scale each year, the processing of PCB products also derives a huge industry market. The application of PCB laser cutting processing technology is an important part of it.

PCB laser cutting technology

The application of PCB laser cutting machine technology in the PCB industry started early, but it has always been tepid and can only be applied in special industries, such as scientific research, military industry and other fields. The main reason is the early use of CO2 laser cutting, which has greater thermal impact and lower efficiency. With the development of laser technology, more and more light sources are used in the PCB industry, such as ultraviolet, green light, optical fiber, CO2, and so on. On the other hand, the PCB industry is developing in the direction of lightness, thinness, high integration, and high precision. Traditional processes have different problems such as burrs, dust, stress, vibration, and inability to process curves. Therefore, in the PCB field, the application advantages of laser cutting and board splitting technology have gradually become prominent. Its advantages are that non-contact processing is stress-free and will not deform the board; it will not generate dust; the cutting edges are smooth and tidy, and there will be no burrs; PCB boards with components can be processed; arbitrary graphics can be processed. However, laser technology still has shortcomings, and the processing efficiency cannot be compared with traditional technology. Therefore, laser cutting technology is currently only used in fields that require high processing accuracy.

PCB laser drilling technology

In addition to PCB laser cutting, PCB laser drilling has become the mainstream of market processing. By CO2 laser or ultraviolet laser drilling of PCB circuit boards, blind holes and through holes can be drilled at high speed. This method has high processing efficiency and good effect. It is a pity that this equipment has been controlled by foreign manufacturers for a long time. Although it is small-scale domestically, the overall market share is still very small, and technological breakthroughs are needed.

Laser cutting technology of soft and hard board

FPCA soft board cutting has been fully processed by UV ultraviolet laser cutting machine in the market, and the development momentum has been good in the past two years. It is facing the development of automatic loading and unloading and high-power cutting, and generally uses ultraviolet lasers above 15W for processing. UV laser cutting machine is also used on the soft and hard board.

PCB QR code laser marking

The application of PCB QR code marking is on the one hand to enhance the brand effect, on the other hand, it is convenient for product quality traceability and market direction traceability. It is convenient to manage and is conducive to improving the competitiveness of the product market. It has been fully developed in the market, and there will be a very broad market in the future. In the application of PCB two-dimensional code laser engraving, UV ultraviolet laser marking machine, CO2 laser marking machine, fiber laser marking machine, green laser marking machine, etc. are selected according to different paint surfaces and materials.
