    AI Overview
    A 355nm UV laser provides high-precision, non-contact marking on keyboards, creating clear, durable, and high-contrast characters without heat deformation or burning. Using "cold light" photochemical reactions, this technology is ideal for plastic keys, producing superior results compared to traditional inks. Typical systems (e.g., 5W) offer fast, eco-friendly, and maintenance-free, permanent marking. 
    Key Advantages for Keyboard Marking 
    • Cold Processing: The 355nm wavelength breaks molecular bonds directly, minimizing heat stress and damage on plastic, rubber, or metal keycaps.
    • High Precision: The small focal spot allows for ultra-fine marking of small characters, symbols, and intricate logos.
    • Non-contact & Durable: Because there is no physical contact with the keyboard, delicate, uneven, or flexible surfaces are marked easily, creating high-contrast, permanent, and wear-resistant characters.
    • Application Areas: Suitable for 3C electronics, including computer accessories, laptop keyboards, phone cases, and plastic button switches. 
    System Specifications and Features 
    • Wavelength: 355nm (Ultraviolet).
    • Power: Common configurations include 3W, 5W, 10W, and 20W, with 5W often used for keyboards.
    • Marking Area: Usually ranges from
      70
      ×70
      mm
       to
      300
      ×300
      mm
       or more, with
      110
      ×110
      mm
       being standard.
    • Components: Often features JPT laser sources, Sino-Galvo scanners, and EZCAD software. 
    Popular options include industrial-grade markers from Keyence, Cloudray, and WaveTopSign.
