Advantages of high power uv laser cutting flexible circuit boards

In 2019, 5G will appear more and more frequently in people's lives, and more and more people are aware of 5G and pay attention to 5G services/mobile phones. With the characteristics of "high speed, low latency, and large capacity", 5G is becoming the latest outlet for the technology industry. As the commercialization of 5G approaches, new market demand will be released and benefit all links of the industry chain. From the perspective of the development trend of 5G commercial equipment and products, the flexible circuit board industry will become one of the biggest beneficiaries.

The processing technology of flexible circuit boards is also constantly innovating

In the electronics industry, flexible circuit boards can be said to be the blood vessels for electronic products. Flexible circuit boards have the advantages of high wiring density, lightness and thinness, bendable, and three-dimensional assembly. They are compatible with market development and are in growing demand. While the industry is developing rapidly, the processing technology of flexible circuit boards is constantly innovating.

Laser as a non-contact processing tool

As a non-contact processing tool, laser can apply high-intensity light energy (650mW/mm2) on a small focus (100~500μm). Such high energy can be used to laser cut, drill, and drill materials. Marking, welding, scribing and various other processing.

Advantages of laser cutting flexible circuit boards:

Due to the dense lines and increasing spacing of FPC products, and the increasing complexity of FPC graphics contours, this makes it more and more difficult to make FPC molds. Laser cutting of flexible circuit boards adopts numerical control processing, which does not require mold processing, and saves time. Mold cost.

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

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 called non-contact processing, which effectively avoids damage and deformation of processed materials.
