Laser Scribing Machine

A laser scribing machine is a high-precision, non-contact laser processing system used to cut, isolate, or pattern thin-film materials—especially in perovskite solar cells and flexible electronics. As a core component of an advanced laser patterning system, it enables accurate execution of P1, P2, and P3 scribing steps, critical for cell efficiency and module integrity. Our laser scribing solutions—also referred to as laser scribe machines—feature micron-level accuracy, automated alignment, and multi-wavelength laser compatibility, making them ideal for high-speed, low-damage processing in both R&D and industrial-scale production environments.

Laser Scribing Machine Working Principle

Laser scribing machine operates by focusing a high-energy laser beam onto the surface of a material to perform precise micro-patterning, cutting, or isolation. The laser beam is controlled by galvanometer scanners or precision motion stages, enabling the system to selectively ablate thin-film layers without mechanical contact. Depending on the application, different laser types (such as UV, green, or IR with nanosecond to femtosecond pulse widths) are used to tailor energy absorption and minimize thermal damage.

Laser Scribing Machine Advantages

——Compared to traditional mechanical scribing

• Precision: Laser scribing achieves line widths as narrow as 10–20 μm, versus 50–100 μm for mechanical methods.

• Speed: Typical laser scribing speed reaches 300–1,000 mm/s, enabling high-throughput production.

• Non-contact: Eliminates tool wear and physical damage, improving yield and reducing maintenance.

• Thermal control: Especially with femtosecond lasers, the heat-affected zone is limited to <1 μm, compared to several microns in mechanical or longer-pulse laser systems.

• Flexibility: Easily reprogrammed for different patterns without physical tooling changes.
