355nm UV laser for copper foil scribing and fine cutting

 

Solid-state UV laser cuts copper foil with smooth edges without carbonization

Scribe copper foil, use UV laser to have smooth edges without carbonization, fine cutting

Copper foil, like gold foil, is a very, very thin sheet of metal. Although very thin, it has a very important role in industrial manufacturing: it is an important material for manufacturing CCL (copper clad laminate), and CCL is the substrate material of PCB (printed circuit board), and PCB is almost all electronic equipment Important components. Therefore, electrolytic copper foil is also known as the "neural network" of electronic product signal and power transmission and communication. However, processing this important industrial material is not easy. Today, the editor of RFH will share with you one of the processing techniques.

Copper foil scribing and cutting process

 

Because the manufacturing difficulty and cost of copper foil are very high, when cutting and processing copper foil, the process requires sufficient fineness to reduce the scrap rate of materials.

 

At present, UV laser cutting is the most suitable process for scribing and cutting copper foils that the industry has unanimously recognized. The principle of ultraviolet laser cutting is to realize cutting by scanning back and forth with a high-energy beam of galvanometer. Its advantage is that the laser used in it is a cold light source, which has little thermal effect on the processed material, fine spot, and small processing gap. Therefore, when cutting and scribing copper foil, the processing edge has no carbonization, no burr, and no copper The foil is deformed to realize the roll-to-roll processing mode.

 

As early as a few years ago, when the demand for electronic grade copper foil in domestic and foreign markets began to increase, RFH began to develop and produce UV laser products that can be used in copper foil scribing and cutting. After years of research, RFH has successfully created such an ultraviolet laser, which has been recognized and applied by domestic and foreign manufacturers.

 

Expert Ⅱ 355 series ultraviolet diode pumped pulsed solid-state laser is one of them. It has a short pulse width (<14ns@30K), superior beam quality (M2<1.2) and perfect spot characteristics (spot ellipticity>90%). It is strictly guaranteed in all frequency ranges, so it is When threading and cutting copper foil materials, the heat-affected area is small, and the material will not be deformed, and the effect is very good.

 

The pump and Q-switch core components of Expert Ⅱ 355 series ultraviolet lasers are all imported brands. The parts cooperate with domestic first-line brand suppliers, and the quality is guaranteed; the production management system is very rigorous, and the whole process is produced in a dust-free workshop, so it can be used in industrial, Under extreme conditions of scientific research, maintaining consistent and stable quality, constant beam quality and high-efficiency power consumption are the reasons why the service life is better than that of peers.

 

RFH has worked hard for 12 years and has delivered one after another first-class lasers to all walks of life at home and abroad. As a result, it has won high recognition and good reputation from users, and has established an excellent brand image in the nanosecond laser industry.

Warm reminder: RFH 10-15W high-power UV laser will attend Sino-Pack in China International Packaging Industry Exhibition on March 4-6, 2020 and Shanghai Optical Expo in Munich on March 18-20
