Laser micro-etching provides micron-level precision. Different materials absorb laser energy differently, allowing conductive thin films to be removed without damaging the substrate.

By removing surface thin films on both sides, different circuit patterns can be formed while the insulating layer in between functions as a sensing structure.

Laser micro-etching is a physical rather than chemical process, making it environmentally friendly and pollution-free. It also offers low long-term production costs, stable precision, and high yield performance.
