The marking effect of cold light source UV laser on PET film is clear and environmentally friendly

As a global industrial-grade solid-state laser manufacturer, this issue of RFH Laser Classroom explains the application of UV lasers in cutting and engraving thin-film materials for everyone.

Ultraviolet laser can be used to cut PET film, PI film and other transparent material films; it can also etch film materials with conductive metals, including constantan, copper, aluminum, ITO, silver paste, FTO and other film materials. Etching, resistance adjustment, etc., typical applications are copper thin film laser etching; in addition, PI films and other films attached to glass, white goods and other materials can also be cut without damaging the substrate. Typical applications include cover film UV laser cutting.

Ultraviolet laser is a cold light source. The heat affected zone of laser cutting is particularly small as 10μm, so there is no thermal effect, and the problem of film material deformation or scorching is avoided.

In the 13 years of Seiko, the RFH Expert Ⅱ 355nm UV laser has been fully penetrated into all aspects of the 3C industry, especially in the fields of cutting and engraving film materials and 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 writing is clear and easy to identify, 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, the heat-affected area during processing is small, and it supports digital intelligent power control, simple operation, and low hands-on 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.

At present, RFH Laser has a global industrial laser research and development team composed of professors, experts, and doctors at home and abroad. At the same time, it has established an application process research and development department, a laser research and development department, and an electrical research and development department. This laser product can maintain consistent stable quality, constant beam quality, high-efficiency power consumption characteristics under extreme industrial and scientific research conditions, and win the trust of users from all walks of life with its superior cost performance and high reliability.
