In some cities, the three major operators have begun to deploy 5G on a large scale. To realize 5G technology, the use of circuit boards is indispensable. In the electronics industry, flexible circuit boards can be said to be the blood transfusion channel of electronic products. Especially with the trend of electronic equipment becoming thinner, smaller, wearable, and foldable, flexible circuit boards have the advantages of high wiring density, thinness, bendability, and three-dimensional assembly, which are highly compatible with market development trends and have an increasingly strong demand.

For processing, the common traditional processing methods include die cutting, milling cutter, stamping, etc. However, this mechanical contact type of board separation process has stress, is prone to burrs, dust, and is not accurate enough, so it is gradually replaced by laser cutting. Flexible circuit board laser cutting machine is a non-contact processing tool. It can apply high-intensity light energy (650mW/mm2) on a very small focus (100-500UM). Such high energy can be used for laser cutting, drilling, marking, welding, marking and other processing of materials.

Using a flexible circuit board laser cutting machine to cut PCB/FPC does not require several molds like traditional stamping, saving time and cost; and laser cutting is a non-contact process, eliminating the damage to components in contact processes such as mechanical stamping, greatly improving the yield rate. Using laser to cut PCB/FPC is an inevitable trend of development.

1. As the line density and pitch of FPC products continue to increase, and the contour of FPC graphics becomes more and more complex, it becomes increasingly difficult to make FPC molds. Laser cutting of flexible circuit boards uses CNC processing, which does not require mold processing and saves mold opening costs;

2. Due to the shortcomings of mechanical processing itself, which restricts the processing accuracy, laser cutting of flexible circuit boards uses high-performance ultraviolet laser light sources with good beam quality. The cutting effect is better;

3. Since 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 method, which effectively avoids damage and deformation of the processing material.

With the development of flexible electronic technology, various electronic products have been developed. The application of flexible circuit board laser cutting machines will drive a trillion-yuan market, help traditional industries increase their added value, and bring revolutionary changes to the industrial structure and human life.
