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 for shape cutting, or plastic source information such as two-dimensional code etching. When ultraviolet laser cutting, the heat-affected zone is particularly low. As small as 10μm, it can effectively avoid deformation, scorching, or burrs caused by heat.

As a global industrial-grade solid-state laser manufacturer, RFH’s best-selling product Expert Ⅱ 355nm UV laser has penetrated into all aspects of the 3C industry, especially in the field of FPC flexible circuit board marking, it has established a good brand image.

RFH Expert Ⅱ 355nm UV laser has a wide range of repetition frequency (single pulse to 200kHz), can be absorbed by the material, and is less destructive to the material, sterile 0 pollution, the identification code does not fall off, the handwriting is clear and easy to identify, which is very suitable Mark high-density circuit boards.

At the same time, it has superior beam quality (M2<1.2), which is strictly guaranteed in all frequency ranges; pulse width <20ns@30k, heat-affected area is small during processing, and supports digital intelligent power control, simple operation and low cost , To meet the rapid mass production needs of enterprises.

In terms of production, RFH has a rigorous quality management system mechanism, from purchasing-pre-production quality inspection control-rigorous assembly process-finished product testing-warehousing quality inspection-pre-delivery inspection-after-sales service, all levels of control to ensure stable quality And the equipment parameters are consistent with the actual operating parameters. This is the reason why the service life of RFH brand lasers is better than that of peers.

In addition, RFH has the advantages of independent research and development of laser power technology, which can update the power control system functional modules in time, and improve the functional modules according to laser requirements.

After 13 years of development and precipitation, RFH Laser currently has a global industrial laser R&D team composed of domestic and foreign professors, experts, and PhDs. At the same time, it has established an application process R&D department, a laser R&D department, and an electrical R&D department, with strong technical backing to ensure Each laser product developed and produced can maintain consistent and stable quality, constant beam quality, high-efficiency power consumption under extreme industrial and scientific research conditions, and win the trust of users from all walks of life with superior cost performance and high reliability.
