Laser marking on POCT (Point-of-Care Testing) or in vitro diagnostic (IVD) test cards offers several advantages and is applied in various scenarios:

1. Micro Marking: Laser marking technology enables precise marking on small areas of POCT or in vitro diagnostic test cards, suitable for medical devices that require highly precise identification.

2. High Resolution: Laser marking provides high-resolution graphics and text markings, ensuring clear visibility of information on diagnostic test cards.

3. Rapid Production: Laser marking typically possesses high-speed processing capabilities, suitable for the rapid production required in the manufacturing of medical devices, contributing to increased production efficiency.

4. Permanent Marking: Laser-marked identifications are usually permanent, resistant to wear or fading, ensuring long-lasting and reliable information.

5. Automation Integration: Laser marking technology can be integrated with automated systems, achieving a highly automated production process, helping to reduce production costs and enhance consistency.

In terms of applications, laser marking is common in the manufacturing of POCT devices and in the production of in vitro diagnostic test cards in the medical field. For instance, in vitro diagnostic test cards may include markings such as patient information, batch numbers, production dates, and laser marking ensures the clarity and readability of this information. Additionally, due to the need for rapid and accurate diagnostic results in POCT, the efficiency and precision of laser marking make it a common method in the production process.
