5g appears more and more frequently in people's lives. More and more people know about 5g and pay attention to 5g services / mobile phones. 5g has the characteristics of "high speed, low delay and large capacity", and is becoming the latest outlet of the science and technology industry. As 5g commercial application approaches, new market demands will be released and benefit all links of the industrial chain. From the R & D trend of 5g commercial equipment and products, the flexible circuit board industry will become one of the largest beneficiaries.

In the electronic industry, flexible circuit board can be said to be the blood transfusion pipeline of electronic products. Flexible circuit board has the advantages of high wiring density, light and thin, flexible and three-dimensional assembly. It is suitable for the development of the market and has an increasingly strong demand. With the rapid development of the industry, the processing technology of flexible circuit boards is also constantly innovating.

As a non-contact machining tool, laser can be used at a very small focus (100 ~ 500 μ m) High intensity light energy (650 MW / mm2) is applied to the material, and such high energy can be used for laser cutting, drilling, marking, welding, scribing and other processing.

Advantages of laser cutting flexible circuit board:

As the lines of FPC products are dense and the spacing is increasing, and the FPC graphic contour is becoming more and more complex, it is becoming more and more difficult to make FPC molds. The laser cutting flexible circuit board adopts the form of numerical control processing, which eliminates the need for mold processing and saves the cost of mold opening.

Due to the shortage of mechanical processing, which restricts the processing accuracy, the laser cutting flexible circuit board uses a high-performance ultraviolet laser light source, which has good beam quality and better cutting effect.

As the traditional processing technology is a contact machining method, it will inevitably produce processing stress on FPC and may cause physical damage. Laser cutting flexible circuit board is a non-contact processing, which can effectively avoid damage and deformation of processed materials.
