Solid-state UV laser cutting FPC flexible circuit board without burrs

With the rise of 5G technology, smart phones will usher in large-scale popularization and replacement, which will also bring new growth demands to the FPC soft board market.

Various consumer electronic products such as smart phones, PDAs, digital cameras, etc. are developing in the direction of thinner, smaller and more multifunctional. FPC soft boards are flexible, thin, and have high pin density, flexible bending, and ever-changing shapes. Integrating multiple benefits into one, it caters to the trend of lighter, thinner and flexible electronic products, and gradually replaces the closed ends of hard boards in some aspects, becoming the main connection accessories in electronic devices.

In the production process of FPC flexible circuit boards, a high-performance 355nm wavelength ultraviolet laser (commonly known as cold light source) is required
