Application of circuit board 30 watt fiber laser under 5G technology

In some cities in China, the three major operators have started to lay out 5G on a large scale. To realize 5G technology, the use of circuit boards is indispensable. In the electronic industry, the flexible circuit board can be said to be the blood transfusion pipeline of electronic products. Especially under the trend of thinness, miniaturization, wearable and foldable electronic equipment, flexible circuit boards have the advantages of high wiring density, thin, flexible and three-dimensional assembly, and the market development trend is appropriately high, and the demand is increasingly vigorous 30 watt fiber laser.

For processing, the common traditional processing methods are knife die, milling cutter, stamping, etc. But this belongs to the mechanical contact plate process, stress, easy to produce burrs, dust, precision is not high enough, so it is gradually replaced by laser cutting process. Flexible circuit board laser cutting machine as a non - contact machining tool. It can apply high intensity light energy (650mW /mm2) at a very small focus (100-500um). This high energy can be used for laser cutting, drilling, marking, welding, marking and other processing of materials metal fiber laser cutter.


Using flexible circuit board laser cutting machine to cut PCB/FPC, without the need for several kinds of die like traditional stamping, save time and cost; And laser cutting for non-contact processing, eliminate mechanical stamping and other contact processing damage to components, greatly improve the rate of finished products, the use of laser cutting PCB/FPC has been an inevitable trend of development.


1. Due to the increasing line density and pitch of FPC products, coupled with the increasing complexity of FPC graphics contour, which makes the production of FPC mold more and more difficult, laser cutting flexible circuit board by NUMERICAL control processing form, without mold processing, save the cost of mold;

2. Due to the lack of machining itself, which restricts the processing accuracy, the laser cutting flexible circuit board adopts high performance ULTRAVIOLET laser light source beam quality is good. Better cutting effect;

3. Because the traditional processing technology is a contact machining method. It is necessary to produce processing stress on FPC, which may cause physical damage. Laser cutting flexible circuit board is non-contact processing, which can effectively avoid material damage and deformation

With the development of flexible electronic technology, various electronic products are applied. The application of flexible circuit board laser cutting machine will drive a trillion yuan scale market, assist traditional industries to enhance industrial added value, bring revolutionary changes to the industrial structure and human life.
