The application of laser cutting copper film is to remove the copper on the surface of PET film.

The principle of UV laser cutting machine is to use semiconductor UV laser to scan the high-energy beam of the vibrating mirror back and forth. The advantages of UV laser cutting machine are that its laser is a cold light source, which has little thermal impact on the processed material, small processing gap, smooth processing edge and no burrs. It is particularly suitable for cutting ultra-thin metal materials such as copper foil and ultra-thin metal alloys. In addition, it is also widely used in the field of conductive metal films.

Copper foil UV laser cutting application

The difficulty of copper foil cutting lies in the fact that the cutting edge has no carbonization, no burrs, and will not deform the copper foil, and realize the roll-to-roll processing mode. Traditional laser cutting machines, such as fiber laser cutting machines, have large thermal effects and lower precision than UV laser cutting machines. In the eyes of edge carbonization, the thermal effects of the edges will be the warping and deformation of the copper foil. The UV laser cutting machine uses a vibrating mirror to scan, vacuum adsorption at the bottom, and a cold light source to reduce thermal effects, achieving perfect cutting of the copper foil, and is also suitable for ultra-thin metal cutting.

ApplicationCopper film laser cutting

The application of copper film is to remove the copper on the surface of PET film to form a conductive pattern. The process requirements are to remove copper without residue, without affecting conductivity, and without damaging the PET film. Using infrared or green light sources to process this material will either damage the PET film or the copper will not be clean enough, resulting in a short circuit. The advantage of the UV laser cutting mode is that the thermal impact of the surface copper is small and will not damage the PET. In addition, the light in the lower part of the process directly cuts through the PET.
