Application of circuit board laser cutting machine under 5G technology
In some cities, the three major operators have begun to deploy 5G on a large scale. To realize 5G technology, it is inseparable from the use of circuit boards. In the electronics industry, flexible circuit boards can be said to be the blood vessels for electronic products. Especially under the trend of lighter, thinner, miniaturized, wearable, and foldable electronic equipment, flexible circuit boards have the advantages of high wiring density, lightness and thinness, bendable, and three-dimensional assembly, and are appropriately matched to the market development trend., Increasingly vigorous.

For processing, the common traditional processing methods are die, milling cutter, stamping and so on. However, this mechanical contact type splitting process is stressful, prone to burrs, dust, and insufficient precision, so it is gradually replaced by the laser cutting process. The flexible circuit board laser cutting machine is used as a non-contact processing tool. It can apply high-intensity light energy (650mW/mm2) on a small focal point (100-500UM). Such high energy can be used for laser cutting, drilling, marking, welding, scribing and other various materials. Kind of processing.

The use of flexible circuit board laser cutting machine to cut PCB/FPC does not require several molds like traditional stamping, which saves time and cost; and laser cutting is a non-contact processing, which eliminates the damage to components in contact processing such as mechanical stamping. To greatly improve the yield rate, the use of laser cutting PCB/FPC is an inevitable trend of development.
1. As the circuit density and pitch of FPC products continue to increase, and the contours of FPC graphics are becoming more and more complex, this makes it more and more difficult to make FPC molds. Laser cutting of flexible circuit boards uses CNC processing, without mold processing., Save the cost of mold opening;
2. Due to the deficiencies of mechanical processing, which restricts the processing accuracy, the laser cutting flexible circuit board adopts high-performance ultraviolet laser light source with good beam quality. Better cutting effect;
3. Because the traditional processing technology is a contact machining method. It will inevitably produce processing stress on the FPC, which may cause physical damage. Laser cutting of flexible circuit boards is a non-contact processing, which effectively avoids damage and deformation of processed materials.

With the development of flexible electronic technology, various electronic product applications have emerged. The application of flexible circuit board laser cutting machines will drive a trillion-yuan market, assist traditional industries to increase the added value of the industry, and bring revolutionary changes to the industrial structure and human life.
