FPC is an important linking circuit for electronic applications and is an essential component of electronic circuits. CVL overlay film is the partner of FPC and is applied to FPC products to prevent oxidation and solder resist.
Of course FPC itself contains copper and cover film, in today's highly automated, intelligent equipment development, the requirements of FPC products are also increasingly high, but also put forward the FPC products for traceability management, the requirements of the FPC product production process for product quality traceability, the later product application process to achieve product traceability after the sale. This requires the FPC-related products marked with a clear, readable two-dimensional code and SN after-sales code, and UV laser marking machine equipment to easily solve the problem, UV laser marking machine equipment to meet the product quality traceability, after-sales service code marking needs.
CVL covering film usually refers to PI film, the marking process requirements are to mark the surface with a clear and beautiful string or 2D code, and not to penetrate the film layer; FPC copper foil requirements are to mark the surface of the copper foil with a clear 2D code or string, clear, readable, and not to make it deformed. For process requirements, UV laser marking machine production can meet the marking needs of both materials, to meet the process conditions at the same time, flexible use, and configuration of the camera can read the function, automatic identification area marking function. The following picture is the PI film, copper foil products UV laser marking samples.
UV laser marking machine characteristics: the use of high-performance UV laser (cavity frequency doubling technology + TEC cooling technology), the laser beam quality is superior to bring users superior marking effect, UV laser is a cold light source, marking heat-affected zone is particularly small, more suitable for the heat sensitive materials for fine laser marking.
