    AI Overview
    3W 5W 12W 15W Glass Crystal PE PCB Desktop UV Laser Marking ...
    A 15W UV laser is suitable for marking QR codes on PCBs because it provides high-precision, carbon-free marking with a minimal heat-affected zone, which is ideal for delicate electronic components. This cold marking process creates high-definition, permanent codes without damaging the PCB, ensuring a permanent and high-quality mark. 
    Benefits of using a 15W UV laser for PCB QR codes 
    • High precision and resolution: The 355nm UV laser has a very small spot size, allowing for the creation of high-definition and fine-detail QR codes.
    • "Cold marking" process: UV lasers operate at a lower temperature compared to other lasers, producing a minimal heat-affected zone. This means the laser will not damage or scorch the PCB material, which is crucial for protecting delicate electronic components.
    • Carbon-free marking: The process creates clear markings without the carbonization that can occur with other methods.
    • Permanent and durable marking: The markings are permanent, abrasion-resistant, and will not fade over time, ensuring the QR code remains functional.
    • Wide material compatibility: UV lasers are effective on a variety of materials, including flexible PCBs, glass, and plastics commonly used in electronics. 
    Key specifications to look for 
    • Power: 15W is a common and effective power level for this type of application, but other powers are available.
    • Marking speed: Machines can have marking speeds up to 7000mm/s or higher, depending on the model and application.
    • Working area: This can vary, with common options being 110x110mm or 150x150mm, and some machines offering larger areas up to 300x300mm.
    • Positioning system: Systems with a visual CCD positioning system can improve accuracy, especially for automated production lines.
