RFH 355nm UV laser is particularly good at wafer cutting and scribing
The wafer is purified by silicon element (99.999%), and then the pure silicon is made into a long silicon ingot, which becomes the material of the quartz semiconductor for the manufacture of integrated circuits. After photolithography, grinding, polishing, slicing and other procedures, the polysilicon It melts and pulls out the monocrystalline silicon ingots, and then cuts them into thin wafers, which then become silicon wafers.
As the main light source of the wafer laser scribing machine, the RFH ultraviolet laser can accurately track the parts that need to be processed in the wafer cutting design, and perform cold-processed wafer scribing. The RFH ultraviolet laser can maintain the efficiency and clarity of the wafer to a large extent, and its scribing is accurate. Even high-density scribing will never cause repeated scribing problems, resulting in skewed and difficult-to-use effects. It is the best way to speed up production efficiency and quality.
Yesterday, I received Manager Zhou from Dongguan, a manufacturer of wafer laser scribing machines, preparing to purchase a batch of 355nm ultraviolet lasers. This time, Manager Zhou specially came to negotiate the details of the contract. It is understood that this batch of 355nm ultraviolet lasers will be used for wafer cutting and scribing.
"Small size", "±0.02mm high precision", "high power stability", and "high cost performance" are the core advantages of RFH's S9 series ultraviolet lasers. This is also the reason why Mr. Zhou chooses RFH.
Compared with similar products of the same type, the new S9 series lasers launched by Shenzhen RFH in 2020 are smaller in size, more exquisite in design, and more stable in light output. The small and exquisite design means that users do not need to make a large light path, which can greatly reduce costs, save space, and be lightly installed in the field of flying marking equipment. The S9 ultraviolet laser is not only compact, but also has a more stable cavity structure and stronger scalability than similar products. The same cavity can generate lasers of multiple powers, and the stability of different power ranges is greatly improved.
In addition to its compact size, the pump and Q-switch core components of the RFH laser are all imported brands, and the components are cooperating with domestic first-line brand suppliers. From the source of the material procurement ecological chain, ensure the quality of each component. The foundation is well laid. Secondly, there is a rigorous quality management system mechanism, many times of R&D and debugging, carefully built, and the whole process of production in a dust-free workshop; thirdly, it is technology. RFH has a high-level R&D team composed of Tsinghua professors and PhDs, and has established an application process R&D department, a laser R&D department, and an electrical R&D department. From the perspective of users, it develops the stability of the entire laser system of the power supply + laser head + cooling system. Give full play to the best performance.
Our team has been silently doing this kind of research and development and debugging for 13 years. Therefore, with such superior beam quality and perfect spot characteristics, UV lasers can maintain consistent stable quality and high-efficiency power consumption characteristics under extreme industrial and scientific research conditions.
RFH S9 series ultraviolet lasers give users a sense of surprise and steadfastness in other aspects, such as unique Q-switching control technology and internal cavity self-purification system. The unique Q-switching control technology is suitable for various laser application control needs and meets diversified laser processing modes; the internal cavity self-purification system can extend the life of the laser, thereby helping manufacturers to save costs. Because of these two points, wafer laser scribing machine manufacturers will order RFH UV lasers in bulk.
