For thin-film laser cutting applications, how is the cutting performance of this nanosecond solid-state laser?

With the rapid development of thin film technology, it generally has different uses such as heat insulation, waterproof, sealing, insulation, shielding or line protection, and has been widely used in machinery, 3C electronics, aerospace, photovoltaic, printing and other fields.

Common films include PET, PI, CPI, and composite films. Traditional film cutting generally adopts die-cutting method. As the market has higher and higher requirements for film cutting accuracy and product quality, the shortcomings of traditional cutting methods are gradually magnified. mainly reflects in:

1. The mold has certain limitations, and the shape and size of the cutting are relatively fixed;

2. The die-cutting incision is large and the precision is poor, which cannot meet the micro-machining requirements of miniaturization and refinement;

3. After long-term use, the mold is easy to wear and tear, and the replacement of the mold leads to an increase in cost;

4. The product qualification rate is not high, and the production efficiency cannot be improved for a long time;

5. The reliability is low, and it is easy to generate dust, waste gas, waste, etc., which is not conducive to environmental protection;

If the laser cutting process is used, there are many benefits. RFH nanosecond solid-state laser can be selected, and users can choose flexibly according to different purposes. The advantages are as follows:

1. 355nm UV laser processing belongs to cold processing, which is especially suitable for materials such as thin films, the degree of thermal action is greatly reduced, and there is no deformation;

2. High precision: non-contact processing, no mechanical stress;

3. The focused light spot is micron-level, with excellent beam quality (M2<1.2), which can achieve high intensity and can realize high-density lines or micro-hole processing;

4. Good effect: 355nm UV laser has higher single-photon energy, high material absorption rate, and small heat-affected zone. It belongs to the cold working process, and the incision is flat, which can avoid material stretching and deformation, and achieve higher processing accuracy;

5. High yield: ultra-short pulse width <25 ns@100kHz or <15ns@40kHz, the heat energy generated is very small, and the thermal damage to the material is extremely small, which can effectively reduce the carbonization of the material, bring high product qualification rate, improve product quality;

6. Customizable: Users can customize the shape and size of the cutting to easily realize special-shaped cutting without the need to develop a separate mold.

Today, laser has become one of the basic technologies of modern high-end manufacturing, but laser technology is still constantly meeting challenges. As an advanced processing tool, this nanosecond solid-state laser is expected to fully empower industry users and play an important role in applications in various important fields.
