Laser film stripping

Femtosecond laser film stripping and removal

femtosecond laser film stripping is a precision, non-contact process that eliminates the risks of traditional mechanical stripping, such as substrate damage. By using a highly focused laser spot, it can selectively remove various coatings-including polymer insulating layers and oxide layers-while maintaining the original state of the underlying material. This technology is essential for electronics, semiconductors, medical devices and precision manufacturing.

Technical advantages

non-contact and injury-free: Eliminates mechanical wear and chemical contamination, ensuring the integrity of fragile substrates.
Micron-level accuracy: to achieve no damage removal, etching accuracy of ≤ ± 1 micron, depth control up to ≤ 0.1 microns.
Versatile compatibility: Adapt to complex geometries (flat, tubular and curved) and process a wide range of materials, including metals, polymers, ceramics and glass.
Efficient and scalable: Highly stable and repeatable, ideal for R & D prototyping and mass production.
