Characteristics of UV laser marking machine and its application in FPC and PI film

FPC is an important connecting line in the field of electronic applications and an indispensable component of electronic circuits. CVL cover film is a partner of FPC, and it can effectively play an anti-oxidation and welding role when attached to FPC products. Of course, FPC itself consists of copper and cover film. In today's development of highly automated and intelligent equipment, the requirements for FPC products are getting higher and higher, and the traceability management of FPC products, the product quality traceability of the FPC product production process, and the after-sales traceability of products have also been proposed. This requires clear marking of FPC-related products, readable QR codes, and SN after-sales codes. For this application, LASEYER has developed targeted FPC copper foil and cover film UV laser marking equipment to meet the needs of product quality traceability and after-sales service code marking.

CVL cover film usually refers to PI film, and its marking process requires marking a clear and beautiful string or QR code on the surface without penetrating the film layer. The requirement of FPC copper foil is to mark a clear QR code or string on the surface of the copper foil, which is clear and readable without deformation.

According to the process requirements, the UV laser marking machine products developed by LASE LASER can effectively meet the marking requirements of both materials, meet the process conditions, are flexible to use, and are equipped with camera readable functions and automatic identification area marking functions. The following figure shows an example of UV laser marking of PI film and copper foil products:

UVFeatures of laser marking machine: It adopts high-performance ultraviolet laser (intracavity dual-frequency technology + TEC cooling technology), and the laser beam quality is excellent, which brings high-quality marking effect to users. Ultraviolet laser is a cold light source, and the heat-affected zone is particularly small during marking, which is more suitable for materials that are sensitive to heat.
