Characteristics of high frequency pulsing solid state laser and its application in FPC and PI film

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

FPC is an important connection line in the field of electronic applications and an indispensable part of electronic circuits. CVL cover film is a partner of FPC, and it can effectively exert anti-oxidation and welding effects on FPC products. Of course, the FPC itself includes copper and coverlay. In the development of today's highly automated and intelligent equipment, the requirements for FPC products are getting higher and higher, and the traceability management of FPC products, product quality traceability in the production process of FPC products, and after-sales traceability of products are also proposed. This requires clearly marked FPC related products, readable QR codes and SN aftermarket codes. For this application, Lesser Laser has developed targeted FPC copper foil and overlay film UV laser marking equipment to meet product quality traceability and after-sales service code marking needs.

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

CVL cover film usually refers to PI film, and its marking process requires that a clear and beautiful string or two-dimensional code be marked on the surface without penetrating the film layer. The requirement of FPC copper foil is to mark a clear two-dimensional code or string on the surface of the copper foil, which is clearly readable and not deformed.

According to the process requirements, the UV laser marking machine products developed by RFH Laser can effectively meet the marking requirements of two materials, meet the process conditions, and are flexible in use. The following picture shows an example of UV laser marking of PI film and copper foil products:

Features of UV laser marking machine: High-performance UV laser (intracavity dual-frequency technology + TEC refrigeration technology) is used, and the laser beam quality is superior, bringing high-quality marking effects 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 sensitive to heat impact.
